Xen users - Nov 2011 - [XCP] Error when trying to import vmware images

Hi list,

I have recently migrated to XCP from Vmware Server 2 and have run into
issues importing the VM''s

Following citrix''s guide I tried using XenCenter to do the import
directly
on the vmdk files
this resulted in XenCenter logging this error:

 "Failed to import. ---> System.Exception: Failed to import virtual disk
file. ---> System.Xml.XmlException: Root element is missing."

Followed by a stack trace (I can attach full logs if requested)

I get this same error when trying to import exported OVF files from VMware
Workstation

The citrix guide also mentions using xe vm-import, this gives me:

[root@xcp ~]# xe vm-import filename=/mnt/vmware/MyVM.vmdk
sr-uuid=2c8e28b5-e0b4-2901-9635-1c824f43aeb6
The VM could not be imported.
msg: INTERNAL_ERROR: [ Failure("int_of_string") ]

I have also run "qemu-img convert -f vmdk MyVM.vmdk -O raw
xen_compat.img"
and tried to "xe vm-import" the img file but was presented with the
same
error.

What am I doing wrong here?

For anyone interested, I have diagnosed the problem...

It appears as though the "Import VM" feature of XenCenter relies on a
hidden "Transfer VM" that exists in XenServer but interestingly not
XCP.

I found this guide from Citrix to restore the Transfer VM on a XenServer -
http://blogs.citrix.com/2010/12/09/diagnosing-xenserver-appliance-wizard-failures/-
and will attempt to copy the Transfer VM into my XCP server and
install
it there.

I will keep the list updated on my progress.

It would be nice to know why the Transfer VM was not included with XCP 1.1
and whether it will be in XCP 1.5 ?

Success!

copying /packages.transfer-vm/xenserver-transfer-vm-6.0.0-50762p.noarch.rpm
from the XenServer 6.0 install ISO to my XCP 1.1 server and installing it
(rpm -ivh xenserver-transfer-vm-6.0.0-50762p.noarch.rpm) creates the
transfer vm needed to do (vmware) imports from XenCenter

I also bumped my xapi version up to 6.0 (see
http://wiki.xen.org/xenwiki/XenCenterXCP) but I don''t think this was
required.

Hope this info helps someone else out there and looking forward to seeing
the transfer vm as part of XCP 1.5 ( ?? )

Could someone please tell me to rtfm so i can reply with vague comments
about Germans and Faulty Towers ?
It seemed to work just fine for another thread on this list, it now has 47
replies.. all spammy spam spam spam but at least the OP doesn''t feel
like
hes talking to a brick wall.
Maybe I''m the only one using XCP, maybe your all zombies.. cat disco.

Maybe this will help, Jordan: http://xkcd.com/293/

just replace toaster with XCP and you''re there.

More usefully:

There''s a citrix article/tool for doing vmware conversions:
http://support.citrix.com/article/CTX116603

The article suggests exporting to OVF from vmware first (I was using vmware
ESXi myself), which works, but it''s really slow. So if you have a big
300GB
VM like I did, you can instead just directly copy out the VMDK files (via
sftp, or via HTTP from the ESX web interface) and go from there.

The main catch is that before doing a vmdk conversion with xenconvert, you
need to consolidate everything down to a single vmdk to avoid headaches
(e.g. delete all snapshots, etc).. xenconvert doesn''t handle multiple
vmdks
at once.

I can''t remember exactly why, but myself, I ran into some
difficulties..
and I remember I ended up converting my vmdks to VHDs first, and then I
successfully used this acronis tool to migrate those VHDs into XCP:
http://kb.acronis.com/content/1815

I wanted to run that acronis tool from a separate linux box, so I setup the
xe management CLI on another machine like this:
http://wiki.xen.org/xenwiki/XCP_Install_CLI

Cheers,
Andrew

ah neat also, just saw the "solved" email from before that I missed.

Did that completely work for you? e.g. basically let you use xencenter to
directly import a vmdk successfully into xcp 1.1?

Cheers,
Andrew

Yep, after installing the transfervm package xencenter imported my vmdk
images perfectly into XCP
