[Libguestfs] [PATCH UNFINISHED] v2v: Split up huge manual page into smaller pages.
The primary virt-v2v(1) page now contains a more concise overview of
virt-v2v, along with things like detailed options documentation which
we would expect in a tool manual.
The documentation for VMware, Xen, local output, oVirt and OpenStack
has been moved to new pages where it is introduced in a more narrative
/ tutorial style. The idea is that people who are interested in
converting from or to these sources will be able to start at
virt-v2v(1) for an overview before moving to one of these new pages
for a friendlier introduction to the topic.
The support matrix has also been moved to a new page called
virt-v2v-support(1). The idea is that downstream packagers will be
more easily able to modify or completely replace this page according
to their support requirements.

+=head1 DESCRIPTION
+
+This page documents how to use L<virt-v2v(1)> to convert guests to
+local files or to a locally running libvirt instance. There are four
+output modes you can select on the virt-v2v command line:
+
+=over 4
+
+=item B<-o libvirt -os> C<POOL>
+
+=item B<-os> C<POOL>
+
+This converts the guest to a libvirt directory pool call C<POOL>, and
+instantiates the guest in libvirt (but does not start it running).
+See L</OUTPUT TO LIBVIRT> below.
+
+I<-o libvirt> is the default if no I<-o> option is given, so you
can
+omit it.
+
+=item B<-o local -os> C<DIRECTORY>
+
+This converts the guest to files in C<DIRECTORY>. A libvirt XML file
+is also created, but unlike I<-o libvirt> the guest is not
+instantiated in libvirt, only files are created.
+
+The files will be called:
+
+ NAME-sda, NAME-sdb, etc. Guest disk(s).
+ NAME.xml Libvirt XML.
+
+where C<NAME> is the guest name.
+
+=item B<-o qemu -os> C<DIRECTORY>
+
+=item B<-o qemu -os> C<DIRECTORY> B<--qemu-boot>
+
+This converts the guest to files in C<DIRECTORY>. Unlike I<-o
local>
+above, a shell script is created which contains the raw qemu command
+you would need to boot the guest. However the shell script is not
+run, I<unless> you also add the I<--qemu-boot> option.
+
+=item B<-o null>
+
+The guest is converted, but the final result is thrown away and no
+metadata is created. This is mainly useful for testing.
+
+=back
+
+=head1 OUTPUT TO LIBVIRT
+
+The I<-o libvirt> option lets you upload the converted guest to
+a libvirt-managed host. There are several limitations:
+
+=over 4
+
+=item *
+
+You can only use a local libvirt connection [see below for how to
+workaround this].
+
+=item *
+
+The I<-os pool> option must specify a directory pool, not anything
+more exotic such as iSCSI [but see below].
+
+=item *
+
+You can only upload to a KVM hypervisor.
+
+=back
+
+=head2 Workaround for output to a remote libvirt instance and/or a
+non-directory storage pool
+
+=over 4
+
+=item 1.
+
+Use virt-v2v in I<-o local> mode to convert the guest disks and
+metadata into a local temporary directory:
+
+ virt-v2v [...] -o local -os /var/tmp
+
+This creates two (or more) files in F</var/tmp> called:
+
+ /var/tmp/NAME.xml # the libvirt XML (metadata)
+ /var/tmp/NAME-sda # the guest?s first disk
+
+(for C<NAME> substitute the guest?s name).
+
+=item 2.
+
+Upload the converted disk(s) into the storage pool called C<POOL>:
+
+ size=$(stat -c%s /var/tmp/NAME-sda)
+ virsh vol-create-as POOL NAME-sda $size --format raw
+ virsh vol-upload --pool POOL NAME-sda /var/tmp/NAME-sda
+
+=item 3.
+
+Edit F</var/tmp/NAME.xml> to change F</var/tmp/NAME-sda> to the
pool
+name. In other words, locate the following bit of XML:
+
+ <disk type='file' device='disk'>
+ <driver name='qemu' type='raw' cache='none' />
+ <source file='/var/tmp/NAME-sda' />
+ <target dev='hda' bus='ide' />
+ </disk>
+
+and change two things: The C<type='file'> attribute must be
changed to
+C<type='volume'>, and the C<E<lt>sourceE<gt>>
element must be changed
+to include C<pool> and C<volume> attributes:
+
+ <disk type='volume' device='disk'>
+ ...
+ <source pool='POOL' volume='NAME-sda' />
+ ...
+ </disk>
+
+=item 4.
+
+Define the final guest in libvirt:
+
+ virsh define /var/tmp/NAME.xml

=head1 DESCRIPTION
-Virt-v2v converts guests from a foreign hypervisor to run on KVM. It
-can read Linux and Windows guests running on VMware, Xen, Hyper-V and
-some other hypervisors, and convert them to KVM managed by libvirt,
-OpenStack, oVirt, Red Hat Virtualisation (RHV) or several other
-targets.
+Virt-v2v converts a single guest from a foreign hypervisor to run on
+KVM. It can read Linux and Windows guests running on VMware, Xen,
+Hyper-V and some other hypervisors, and convert them to KVM managed by
+libvirt, OpenStack, oVirt, Red Hat Virtualisation (RHV) or several
+other targets. It can modify the guest to make it bootable on KVM and
+install virtio drivers so it will run quickly.
There is also a companion front-end called L<virt-p2v(1)> which comes
as an ISO, CD or PXE image that can be booted on physical machines to
virtualize those machines (physical to virtual, or p2v).
-This manual page documents the rewritten virt-v2v included in
-libguestfs E<ge> 1.28.
+=head2 Input and Output
+
+You normally run virt-v2v with several I<-i*> options controlling the
+input mode and also several I<-o*> options controlling the output
+mode. In this sense, "input" refers to the source foreign hypervisor
+such as VMware, and "output" refers to the target KVM-based
management
+system such as oVirt or OpenStack.
+
+The input and output sides of virt-v2v are separate and unrelated.
+Virt-v2v can read from any input and write to any output. Therefore
+these sides of virt-v2v are documented separately in this manual.
+
+Virt-v2v normally copies from the input to the output, called "copying
+mode". In this case the source guest is always left unchanged.
+In-place conversion (I<--in-place>) only uses the I<-i*> options
and
+modifies the source guest in-place. (See L</In-place conversion>
+below.)

-
-Port 443 is used to copy the guest disk image(s). Port 5480 is used
-to query vCenter for guest metadata.
-
-These port numbers are only the defaults. It is possible to
-reconfigure vCenter to use other port numbers. In that case you would
-need to specify those ports in the C<vpx://> URI.
-See L</VCENTER: URI> above.
-
-These ports only apply to virt-v2v conversions. You may have to open
-other ports for other vCenter functionality, for example the web user

-(In the diagram above the arrows show the direction in which the TCP
-connection is initiated, I<not> necessarily the direction of data

-
-Virt-v2v itself does not connect directly to the ESXi hypervisor

C<NO_PROXY>) are

-=head2 VCENTER: SSL/TLS CERTIFICATE PROBLEMS
-
-You may see this error:
-
- CURL: Error opening file: SSL: no alternative certificate subject
- name matches target host name
-
-(You may need to enable debugging with ?virt-v2v -v -x? to see this
-message).
-
-This can be caused by using an IP address instead of the
-fully-qualified DNS domain name of the vCenter server, ie. use
-C<vpx://vcenter.example.com/...> instead of
C<vpx://11.22.33.44/...>
-
-Another certificate problem can be caused by the vCenter server having
-a mismatching FQDN and IP address, for example if the server acquired
-a new IP address from DHCP. To fix this you need to change your DHCP
-server or network configuration so that the vCenter server always gets
-a stable IP address. After that log in to the vCenter server?s admin
-console at C<https://vcenter:5480/>. Under the C<Admin> tab,
select
-C<Certificate regeneration enabled> and then reboot it.

-=head1 INPUT FROM VMWARE OVA
-
-Virt-v2v is able to import guests from VMware?s OVA (Open
-Virtualization Appliance) files. Only OVAs exported from VMware

-
-=head2 OVA: CREATE OVA
-
-To create an OVA in vSphere, use the "Export OVF Template" option
-(from the VM context menu, or from the File menu). Either "Folder of
-files" (OVF) or "Single file" (OVA) will work, but OVA is
probably
-easier to deal with. OVA files are really just uncompressed tar
-files, so you can use commands like C<tar tf VM.ova> to view their
-contents.
-
-=head3 Create OVA with ovftool
-
-You can also use VMware?s proprietary C<ovftool>:
-
- ovftool --noSSLVerify \

- VM.ova
-
-To connect to vCenter:
-
- ovftool --noSSLVerify \
- vi://USER:PASSWORD at vcenter.example.com/DATACENTER-NAME/vm/VM \
- VM.ova
-
-For Active Directory-aware authentication, you have to express the
-C<@> character in the form of its ascii hex-code (C<%5c>):
-
- vi://DOMAIN%5cUSER:PASSWORD at ...
-
-=head2 OVA: IMPORTING A GUEST
-
-To import an OVA file called F<VM.ova>, do:
-
- $ virt-v2v -i ova VM.ova -o local -os /var/tmp
-
-If you exported the guest as a "Folder of files", I<or> if you
-unpacked the OVA tarball yourself, then you can point virt-v2v at the

-
-This is useful in two cases:

-If you find a folder of files called F<I<guest>.vmx>,
-F<I<guest>.vmxf>, F<I<guest>.nvram> and one or more
F<.vmdk> disk

-
-=head2 VMX: REMOVE VMWARE TOOLS FROM WINDOWS GUESTS
-
-For Windows guests, you should remove VMware tools before conversion.
-Although this is not strictly necessary, and the guest will still be
-able to run, if you don't do this then the converted guest will
-complain on every boot. The tools cannot be removed after conversion

-=head2 VMX: GUEST MUST BE SHUT DOWN
-
-B<The guest must be shut down before conversion starts>. If you
don't
-shut it down, you will end up with a corrupted VM disk on the target.
-With other methods, virt-v2v tries to prevent concurrent access, but
-because the I<-i vmx> method works directly against the storage,
-checking for concurrent access is not possible.
-
-=head2 VMX: ACCESS TO THE STORAGE CONTAINING THE VMX AND VMDK FILES
-
-If the vmx and vmdk files aren't available locally then you must
-I<either> mount the NFS storage on the conversion server I<or>
enable
-passwordless SSH on the ESXi hypervisor.
-
-=head3 VMX: Passwordless SSH using ssh-agent
-
-You must also use ssh-agent, and add your ssh public key to
-F</etc/ssh/keys-root/authorized_keys> (on the ESXi hypervisor).
-
-After doing this, you should check that passwordless access works from
-the virt-v2v server to the ESXi hypervisor. For example:
-
- $ ssh root at esxi.example.com
- [ logs straight into the shell, no password is requested ]
-
-Note that password-interactive and Kerberos access are B<not>
-supported. You B<have> to set up ssh access using ssh-agent and
-authorized_keys.
-
-=head3 VMX: Construct the SSH URI
-
-When using the SSH input transport you must specify a remote
-C<ssh://...> URI pointing to the VMX file. A typical URI looks like:
-
- ssh://root at
esxi.example.com/vmfs/volumes/datastore1/my%20guest/my%20guest.vmx
-
-Any space must be escaped with C<%20> and other non-ASCII characters
-may also need to be URI-escaped.
-
-The username is not required if it is the same as your local username.
-
-You may optionally supply a port number after the hostname if the SSH
-server is not listening on the default port (22).
-
-=head2 VMX: IMPORTING A GUEST
-
-To import a vmx file from a local file or NFS, do:
-
- $ virt-v2v -i vmx guest.vmx -o local -os /var/tmp
-
-To import a vmx file over SSH, add I<-it ssh> to select the SSH
-transport and supply a remote SSH URI:

- -i vmx -it ssh \
- "ssh://root at
esxi.example.com/vmfs/volumes/datastore1/guest/guest.vmx" \
- -o local -os /var/tmp
-
-Virt-v2v processes the vmx file and uses it to find the location of
-any vmdk disks.
-
-=head1 INPUT FROM VMWARE ESXi HYPERVISOR
-
-You should use the OVA or VMX methods above (see L</INPUT FROM VMWARE
-OVA> and/or L</INPUT FROM VMWARE VMX>) if possible, as they are much
-faster and require much less disk space than the method described in
-this section.
-
-You can use the L<virt-v2v-copy-to-local(1)> tool to copy the guest
-off the hypervisor into a local file, and then convert it.

-The VDDK library can be operated in a verbose mode where it gives
-(very) verbose messages. Use ?virt-v2v -v -x? as usual to enable
-verbose messages.
-
-=head1 INPUT FROM XEN
-
-Virt-v2v is able to import Xen guests from RHEL 5 Xen or SLES and
-openSUSE Xen hosts.
-
-Virt-v2v uses libvirt for access to the remote Xen host, and therefore
-the input mode should be I<-i libvirt>. As this is the default, you
-don't need to specify it on the command line.
-
-=head2 XEN: SET UP SSH-AGENT ACCESS TO XEN HOST
-
-Currently you must enable passwordless SSH access to the remote Xen host
-from the virt-v2v conversion server.
-
-You must also use ssh-agent, and add your ssh public key to
-F</root/.ssh/authorized_keys> (on the Xen host).
-
-After doing this, you should check that passwordless access works
-from the virt-v2v server to the Xen host. For example:
-
- $ ssh root at xen.example.com
- [ logs straight into the shell, no password is requested ]
-
-Note that password-interactive and Kerberos access are B<not>
-supported. You B<have> to set up ssh access using ssh-agent and
-authorized_keys.
-
-With some modern ssh implementations, legacy crypto policies required
-to interoperate with RHEL 5 sshd are disabled. To enable them you may
-need to run this command on the conversion server (ie. ssh client),
-but read L<update-crypto-policies(8)> first:
-
- # update-crypto-policies LEGACY
-
-=head2 XEN: TEST LIBVIRT CONNECTION TO REMOTE XEN HOST
-
-Use the L<virsh(1)> command to list the guests on the remote Xen host:
-
- $ virsh -c xen+ssh://root at xen.example.com list --all
- Id Name State
- ----------------------------------------------------
- 0 Domain-0 running
- - rhel49-x86_64-pv shut off
-
-You should also try dumping the metadata from any guest on your
-server, like this:
-
- $ virsh -c xen+ssh://root at xen.example.com dumpxml rhel49-x86_64-pv
- <domain type='xen'>
- <name>rhel49-x86_64-pv</name>
- [...]
- </domain>
-
-B<If the above commands do not work, then virt-v2v is not going to
-work either>. Fix your libvirt configuration or the remote server
-before continuing.
-
-B<If the guest disks are located on a host block device>, then the
-conversion will fail. See L</XEN OR SSH CONVERSIONS FROM BLOCK DEVICES>
-below for a workaround.
-
-=head2 XEN: IMPORTING A GUEST
-
-To import a particular guest from a Xen server, do:
-
- $ LIBGUESTFS_BACKEND=direct \
- virt-v2v -ic 'xen+ssh://root at xen.example.com' \
- rhel49-x86_64-pv \
- -o local -os /var/tmp
-
-where C<rhel49-x86_64-pv> is the name of the guest (which must be shut
-down).
-
-In this case the output flags are set to write the converted guest to
-a temporary directory as this is just an example, but you can also
-write to libvirt or any other supported target.
-
-Setting the L<backend|guestfs(3)/BACKEND> to C<direct> is a
temporary
-workaround until
-L<libvirt bug 1140166|https://bugzilla.redhat.com/1140166> is fixed.
-
-=head2 XEN OR SSH CONVERSIONS FROM BLOCK DEVICES
-
-Currently virt-v2v cannot directly access a Xen guest (or any guest
-located remotely over ssh) if that guest?s disks are located on host
-block devices.
-
-To tell if a Xen guest uses host block devices, look at the guest XML.
-You will see:
-
- <disk type='block' device='disk'>
- ...
- <source dev='/dev/VG/guest'/>
-
-where C<type='block'>, C<source dev=> and C</dev/...>
are all
-indications that the disk is located on a host block device.
-
-This happens because the qemu ssh block driver that we use to access
-remote disks uses the ssh sftp protocol, and this protocol cannot
-correctly detect the size of host block devices.
-
-The workaround is to copy the guest over to the conversion server,
-using the separate L<virt-v2v-copy-to-local(1)> tool, followed by
-running virt-v2v. You will need sufficient space on the conversion
-server to store a full copy of the guest.
-
- virt-v2v-copy-to-local -ic xen+ssh://root at xen.example.com guest
- virt-v2v -i libvirtxml guest.xml -o local -os /var/tmp

-
-=item 1.
-
-Use virt-v2v in I<-o local> mode to convert the guest disks and
-metadata into a local temporary directory:
-
- virt-v2v [...] -o local -os /var/tmp
-
-This creates two (or more) files in F</var/tmp> called:
-
- /var/tmp/NAME.xml # the libvirt XML (metadata)
- /var/tmp/NAME-sda # the guest?s first disk
-
-(for C<NAME> substitute the guest?s name).
-
-=item 2.
-
-Upload the converted disk(s) into the storage pool called C<POOL>:
-
- size=$(stat -c%s /var/tmp/NAME-sda)
- virsh vol-create-as POOL NAME-sda $size --format raw
- virsh vol-upload --pool POOL NAME-sda /var/tmp/NAME-sda
-
-=item 3.
-
-Edit F</var/tmp/NAME.xml> to change F</var/tmp/NAME-sda> to the
pool
-name. In other words, locate the following bit of XML:
-
- <disk type='file' device='disk'>
- <driver name='qemu' type='raw' cache='none' />
- <source file='/var/tmp/NAME-sda' />
- <target dev='hda' bus='ide' />
- </disk>
-
-and change two things: The C<type='file'> attribute must be
changed to
-C<type='volume'>, and the C<E<lt>sourceE<gt>>
element must be changed
-to include C<pool> and C<volume> attributes:
-
- <disk type='volume' device='disk'>
- ...
- <source pool='POOL' volume='NAME-sda' />
- ...
- </disk>

-
-=head1 OUTPUT TO RHV
-
-This new method to upload guests to oVirt or RHV directly via the REST
-API requires oVirt/RHV E<ge> 4.2.
-
-You need to specify I<-o rhv-upload> as well as the following extra
-parameters:
-

-
-=item I<-oc> C<https://ovirt-engine.example.com/ovirt-engine/api>
-
-The URL of the REST API which is usually the server name with
-C</ovirt-engine/api> appended, but might be different if you installed
-oVirt Engine on a different path.
-
-You can optionally add a username and port number to the URL. If the
-username is not specified then virt-v2v defaults to using
-C<admin at internal> which is the typical superuser account for oVirt
-instances.
-
-=item I<-of raw>
-
-Currently you must use I<-of raw> and you cannot use I<-oa
preallocated>.
-
-These restrictions will be loosened in a future version.
-
-=item I<-op> F<password-file>
-
-A file containing a password to be used when connecting to the oVirt
-engine. Note the file should contain the whole password, B<without
-any trailing newline>, and for security the file should have mode
-C<0600> so that others cannot read it.
-
-=item I<-os> C<ovirt-data>
-
-The storage domain.
-
-=item I<-oo rhv-cafile=>F<ca.pem>
-
-The F<ca.pem> file (Certificate Authority), copied from
-F</etc/pki/ovirt-engine/ca.pem> on the oVirt engine.
-
-=item I<-oo rhv-cluster=>C<CLUSTERNAME>
-
-Set the RHV Cluster Name. If not given it uses C<Default>.
-
-=item I<-oo rhv-direct>
-
-If this option is given then virt-v2v will attempt to directly upload
-the disk to the oVirt node, otherwise it will proxy the upload through
-the oVirt engine. Direct upload requires that you have network access
-to the oVirt nodes. Non-direct upload is slightly slower but should
-work in all situations.
-
-=item I<-oo rhv-verifypeer>
-
-Verify the oVirt/RHV server?s identity by checking the server?s
-certificate against the Certificate Authority.
-
-=back
-
-=head1 OUTPUT TO RHV (OLD METHOD)
-
-This section only applies to the I<-o rhv> output mode. If you use
-virt-v2v from the RHV-M user interface, then behind the scenes the
-import is managed by VDSM using the I<-o vdsm> output mode (which end
-users should not try to use directly).
-
-You have to specify I<-o rhv> and an I<-os> option that points to
the
-RHV-M Export Storage Domain. You can either specify the NFS server
-and mountpoint, eg. S<C<-os rhv-storage:/rhv/export>>, or you can
-mount that first and point to the directory where it is mounted,
-eg. S<C<-os /tmp/mnt>>. Be careful not to point to the Data
Storage
-Domain by accident as that will not work.
-
-On successful completion virt-v2v will have written the new guest to
-the Export Storage Domain, but it will not yet be ready to run. It
-must be imported into RHV using the UI before it can be used.
-
-In RHV E<ge> 2.2 this is done from the Storage tab. Select the
-export domain the guest was written to. A pane will appear underneath
-the storage domain list displaying several tabs, one of which is "VM
-Import". The converted guest will be listed here. Select the
-appropriate guest an click "Import". See the RHV documentation for
-additional details.
-
-If you export several guests, then you can import them all at the same
-time through the UI.
-
-=head2 RHV: TESTING RHV CONVERSIONS
-
-If you do not have an oVirt or RHV instance to test against, then you
-can test conversions by creating a directory structure which looks
-enough like a RHV-M Export Storage Domain to trick virt-v2v:
-
- uuid=`uuidgen`
- mkdir /tmp/rhv
- mkdir /tmp/rhv/$uuid
- mkdir /tmp/rhv/$uuid/images
- mkdir /tmp/rhv/$uuid/master
- mkdir /tmp/rhv/$uuid/master/vms
- touch /tmp/rhv/$uuid/dom_md
- virt-v2v [...] -o rhv -os /tmp/rhv
-
-=head1 OUTPUT TO OPENSTACK
-
-To output to OpenStack, use the I<-o openstack> option.
-
-=head2 OPENSTACK: SETTING UP A CONVERSION APPLIANCE
-
-When virt-v2v is converting to OpenStack, it is unusual in that
-virt-v2v B<must> be running inside a virtual machine running on top of
-the OpenStack overcloud. This virtual machine is called the
-"conversion appliance". Note this virtual machine is unrelated to
the
-guest which is being converted.
-
-The reason for this is because to create Cinder volumes that will
-contain the guest data (for the converted guest) we must attach those
-Cinder volumes to an OpenStack virtual machine.
-
-When virt-v2v is running in the conversion appliance, you must supply
-the name or UUID of the conversion appliance to virt-v2v, eg:
-
- $ openstack server list
- +--------------------------------------+-----------+--------+
- | ID | Name | Status |
- +--------------------------------------+-----------+--------+
- | bbb0147a-44b9-4d19-9a9d-10ca9a984744 | test1 | ACTIVE |
- +--------------------------------------+-----------+--------+
-
- # virt-v2v [...] \
- -o openstack -oo server-id=bbb0147a-44b9-4d19-9a9d-10ca9a984744
-
-or:
-
- # virt-v2v [...] -o openstack -oo server-id=test1
-
-You can run many parallel conversions inside a single conversion
-appliance if you want, subject to having enough resources available.
-However OpenStack itself imposes a limit that you should be aware of:
-OpenStack cannot attach more than around 25 disks [the exact number
-varies with configuration] to a single appliance, and that limits the
-number of guests which can be converted in parallel, because each
-guest's disk must be attached to the appliance while being copied.
-
-=head2 OPENSTACK: AUTHENTICATION
-
-Converting to OpenStack requires access to the tenant (non-admin) API
-endpoints. You will need to either set up your C<$OS_*> environment
-variables or use output options on the virt-v2v command line to
-authenticate with OpenStack.
-
-Normally there is a file called something like C<stackrc>,
-C<overcloudrc> etc which you can simply C<source> to set everything
up.
-
-For example:
-
- export OS_USERNAME=admin
-
-or:
-
- virt-v2v [...] -o openstack -oo os-username=admin
-
-are equivalent, and have the same effect as using I<--os-username> on
-the command line of OpenStack tools.
-
-=head2 OPENSTACK: RUNNING AS ROOT
-
-Because virt-v2v must access Cinder volumes which are presented as
-F</dev> devices to the conversion appliance, virt-v2v must usually run
-as root in I<-o openstack> mode.
-
-If you use C<sudo> to start virt-v2v and you are using environment
-variables for authentication, remember to use the C<sudo -E> option to
-preserve the environment.
-
-=head2 OPENSTACK: GUEST ID
-
- virt-v2v [...] -o openstack -oo guest-id=123-456-7890
-
-You may optionally specify I<-oo guest-id=...> on the command line.
-The ID (which can be any string) is saved on each Cinder volume in the
-C<virt_v2v_guest_id> volume property.
-
-This can be used to find disks associated with a guest, or to
-associate which disks are related to which guests when converting many
-guests.
-
-=head2 OPENSTACK: CONVERTING A GUEST
-
-The final command to convert the guest, running as root, will be:
-
- # virt-v2v [-i options ...] \
- -o openstack -oo server-id=NAME|UUID [-oo guest-id=ID]
-
-If you include authentication options on the command line then:
-
- # virt-v2v [-i options ...] \
- -o openstack -oo server-id=NAME|UUID -oo os-username=admin [etc]
-
-=head2 OPENSTACK: BOOTING THE GUEST
-
-Guests are converted as Cinder volume(s) (one volume per disk in the
-original guest). To boot them use the
-C<openstack server create --volume> option:
-
- $ openstack volume list
- +--------------------------------------+---------------+-----------+
- | ID | Name | Status |
- +--------------------------------------+---------------+-----------+
- | c4d06d15-22ef-462e-9eff-ab54ab285a1f | fedora-27-sda | available |
- +--------------------------------------+---------------+-----------+
- $ openstack server create \
- --flavor x1.small \
- --volume c4d06d15-22ef-462e-9eff-ab54ab285a1f \
- myguest
- $ openstack console url show myguest
-
-=head2 OPENSTACK: OTHER CONVERSION OPTIONS
-
-To specify the Cinder volume type, use I<-os>. If not specified then
-no Cinder volume type is used.
-
-The following options are B<not> supported with OpenStack: I<-oa>,
-I<-of>.
-
-=head1 OUTPUT TO GLANCE
-
-Note this is a legacy option. In most cases you should use
-L</OUTPUT TO OPENSTACK> instead.
-
-To output to OpenStack Glance, use the I<-o glance> option.
-
-This runs the L<glance(1)> CLI program which must be installed on the
-virt-v2v conversion host. For authentication to work, you will need
-to set C<OS_*> environment variables. In most cases you can do this
-by sourcing a file called something like F<keystonerc_admin>.
-
-Virt-v2v adds metadata for the guest to Glance, describing such things
-as the guest operating system and what drivers it requires. The
-command C<glance image-show> will display the metadata as
"Property"
-fields such as C<os_type> and C<hw_disk_bus>.
-
-=head2 Glance and sparseness
-
-Glance image upload doesn't appear to correctly handle sparseness.
-For this reason, using qcow2 will be faster and use less space on the
-Glance server. Use the virt-v2v S<I<-of qcow2>> option.
-
-=head2 Glance and multiple disks
-
-If the guest has a single disk, then the name of the disk in Glance
-will be the name of the guest. You can control this using the I<-on>
-option.
-
-Glance doesn't have a concept of associating multiple disks with a
-single guest, and Nova doesn't allow you to boot a guest from multiple
-Glance disks either. If the guest has multiple disks, then the first
-(assumed to be the system disk) will have the name of the guest, and
-the second and subsequent data disks will be called
-C<I<guestname>-disk2>, C<I<guestname>-disk3> etc. It
may be best to
-leave the system disk in Glance, and import the data disks to Cinder.
