necessary change to how input_password is passed around. I moved
the necessary change into the final patch (implementing SSH

[PATCH 00/11] v2v: Change virt-v2v to use nbdkit for input in several modes.
This series (except the last one) changes virt-v2v to use nbdkit for
several input modes:
-i vmx -it vddk: No change in functionality, as this already uses
nbdkit-vddk-plugin, but the code is refactored for the other modes to
use.
-i libvirtxml: Use nbdkit-curl-plugin instead of qemu curl.
vCenter: Use nbdkit-curl-plugin instead of qemu curl.
xen: Use nbdkit-ssh-plugin instead of qemu

Part 2 fix for:
https://bugzilla.redhat.com/show_bug.cgi?id=1842440
Actually this fix on its own should be sufficient, but probably we
want the nbdkit fixes too.
Note this uses actual OCaml 4.05 features! ("let open" and the
Unix.tcgetattr functions). I checked that both features are available
on RHEL 7's OCaml.

The first patch was previously posted here:
https://www.redhat.com/archives/libguestfs/2017-December/msg00018.html
That patch hasn't changed except that I made the ‘input_transport’
variable type-safe.
The second patch adds a significant new mode for liberating data from
VMware: the ability to copy VMs over SSH directly from ESXi
hypervisors. Although this requires enabling SSH access (a

[PATCH] v2v: Implement SSH password authentication for Xen and VMX over SSH.
This isn't quite the full thing. I think that Pino is also working on
replacing the ssh and scp commands in the v2v/input_vmx.ml file with
libssh. Without those changes, -i vmx will still issue raw ssh and
scp commands, which will use ssh-agent (or keyboard-interactive).
The Xen input method doesn't use raw ssh and scp commands, so that one
is OK.

[PATCH 0/3] v2v: Various refactorings.
Use -ip instead of --password-file, and various refactorings.
It strikes me that we should probably deprecate and eventually remove
virt-v2v-copy-to-local. With the introduction of the new SSH and VDDK
transports, and with RHEL 5 Xen becoming more irrelevant, it's no
longer needed.

[PATCH v2v v2] nbdkit: Use cacheextents if possible for vddk input
It does not need configuring and speeds up the process of requesting extents if
the client asks for them one by one (like qemu-img).

[PATCH v2v] v2v: -it vddk: Don't use nbdkit readahead filter with VDDK (RHBZ#1832805).
This is the simplest solution to this problem. There are two other
possible fixes I considered:
Increase the documented limit (see
http://libguestfs.org/virt-v2v-input-vmware.1.html#vddk:-esxi-nfc-service-memory-limits).
However at the moment we know the current limit works through
extensive testing (without readahead), plus I have no idea nor any way
to test if larger limits are supported by

[PATCH INCOMPLETE 0/4] v2v: Add general mechanism for input and output options.
This patch isn't quite complete (see ‘assert false’).
Currently we have a bunch of ad hoc options like --vddk* and --vdsm*
(and proposed to add --rhv*) to handle extra parameters for input and
output modes/transports. This complicates the command line parsing
and also the clarity of the command line (becauseit's not very obvious
which options apply to which side of the conversion).

[PATCH nbdkit] v2v: Disable readahead for VMware curl sources too (RHBZ#1848862).
I'm still testing this fix, so let's hold off the review for the
moment.
Also it may be better to specifically identify problematic servers
rather than disabling this for every curl source. eg. I suspect that
the problem is the Java server used by VCenter, so we might think
about only disabling readahead for that single case.

[PATCH v7 0/6] v2v: Add -o rhv-upload output mode (RHBZ#1557273).
v6 was here:
https://www.redhat.com/archives/libguestfs/2018-March/msg00126.html
This makes a number of significant changes:
- Input and output options now use a uniform set of -io and -oo
parameters.
- For -o rhv-upload, we use ‘-oo rhv-cafile=/tmp/ca.pem’ etc. The
‘--rhv*’ options have been dropped.
- Rearranges the documentation.
- As before includes (untested) support for zero,

[PATCH v4 01/12] v2v: Factor out the nbdkit VDDK code into a new module.
This refactoring takes the nbdkit-specific code from the ‘-it vddk’
mode and puts it into a separate module. The idea is to reuse this
module (in future commits) to support ssh, curl and rate limiting.
This refactoring is not quite neutral because it moves some of the
prechecking into the Nbdkit.create function. This means it will
happen a little bit later in the cycle (in input#source instead

[v2v PATCH] -i libvirt: print URI without connecting
Pass (again) around the libvirt URI string in the various input_libvirt
subclasses so that input_libvirt#as_options does not need to connect to
print the connection URI.
As related change: pass input_conn as non-optional string parameter in
classes that require one (all but input_libvirt_other, basically). This
avoids the need for extra checks.
