Import Xen machines
Hi all,
I'm trying to migrate a Xen server to RHEV.
I am using the virt-v2v, but it is impossible. Whenever I get the error:
# virt-v2v -f /etc/virt-v2v.conf -o rhev -ic xen+ssh://root@srxen05.mutua.es -os nas1b:/vol/rhevAUXaggr1/export srxmsatelite-test2
libvirt error code: 42, message: Domain not found: xenUnifiedDomainLookupByName
Now I want to make other arrangements, and is to convert the machines manually.
Another alternative would be to convert the machines Xen manually. This is possible?
Any ideas?
Thanks.

Hi, the error means srxmsatelite-test2 is a VM name that virt-v2v could not find. Can you doublecheck the name to make sure you have the spelling correct, and check in virsh list whether the VM is there?

Hi, if I boot the virtual machine srxmsatelite-test2, virt-v2v tells me:
# virt-v2v -f /etc/virt-v2v.conf -o rhev -ic xen+ssh://root@srxen05.mutua.es -os nas1b:/vol/rhevAUXaggr1/export srxmsatelite-test2
root@srxen05.mutua.es's password:
virt-v2v: Guest srxmsatelite-test2 is currently blocked. It must be shut down first.
So I have to do with the machine off, I think. Am I wrong? How should I proceed?
Thanks :-)

Yes, to convert a virtual machine using virt-v2v, you need to shut the vm down first on the source machine if it's running.

ok, thanks. But do not understand why I failed and I get the error:
libvirt error code: 42, message: Domain not found: xenUnifiedDomainLookupByName
I tried another option, and is to convert the images so manually. But I can not get it right.
Any idea how I can proceed?
Thanks.

Please run "virsh -c xen+ssh://root@srxen05.mutua.es list --all" and give the output.

Sure, I have turned off earlier, in order to launch the command. However, it is true that it should seem, even in a list off. I will review it does not appear. :-?

Can't see vm named srxmsatelite-test2" in the output. It should have been in the list with a status "shut off".
If the vm srxmsatellite-test2 is on the host, it looks like you are running a very old version of "libvirt" that cannot display shutdown vms. I mean libvirt released with RHEL-5.0 or 5.1.
Can you provde output of "cat /etc/redhat-release" and "rpm -q libvirt" on the xen system?

here is the output.
[root@srxen05 bin]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 5.7 (Tikanga)
[root@srxen05 bin]# rpm -q libvirt
libvirt-0.8.2-22.el5

New case.
I booted the virtual machine. With virsh I exported the configuration.
# virsh dumpxml srxmsatelite-test2 > /tmp/srxmsatelite-test2.xml
I copied the xml file to another server, where I have the utility virt-v2v
I edited the xml file and changed the directory where the disk images.
I copied the disk images to this server. In the xml file and specify the path.
It seems that all starts well, but ultimately fails.
[root@srkmrhev xen]# virt-v2v -i libvirtxml -osd nas1b:/vol/rhevAUXaggr1/export -o rhev --network default srxmsatelite-test2.xml

This problem is not expected to happen with the above libvirt version. I would request you to open a case with Red Hat support with sosreport from xen system, virt-v2v debug output and sosreport from virt-v2v host.
This need to be analyzed in detail.

Does the xen guest configured with a scsi disk inside the guest? how does the "df" look like inside the guest?
