Hi Guillaume,

 

Thank you for the reply back. I am so glad that I received a reply from someone.

I would like to try this option but I am not much familiar with virsh. I am having Oracle VM which is based on Xen. I don’t have a pool listed in “'virsh pool-list'"

 

My existing OracleVM has already the vmdisks folder mounted as a repository. When I do “virsh pool-create" from the Host, any idea will it conflict the existing repository?

 

Also to list the stopped VMs, what entry is to be added in the XML file. Can you help me with that.

 

Thanks a lot

I successfully imported xem vm to oVirt with the GUI

You need libvirt to be able to list the powered-off vm on the xen host first

 

What was missing for me at first was :

 

1) You need a libvirt pool referencing the path to VMs disks.

Verify that's not already the case with 'virsh pool-list',

 

Otherwise create it :

# cat vm-pool.xml
<pool type="dir">
<name>vm-pool</name>
<target>
          <path>/path/to/vmdisks</path>
</target>
</pool>

# virsh pool-create vm-pool.xml
# virsh pool-list ## Should list the newly created pool

 

2) Then each VM need an UUID present in its xml definition file. 

If not present, you can start the vm, do 'virsh dumpxml domainname' and get the UUID for the running VM,

then power it off and edit the xml to add this UUID line, that will make it visible to virsh when powered off. 

You can check now with : 'virsh list --all'

 

3) For a successful import I found that it's also necessary to 

- install a non xen kernel in the vm, 

- and have disk listed by UUIDs in /etc/fstab (maybe not necessary this last one)

 

 

Good luck,

I think that you have to export the BM as OVA or convert it to KVM before being able to import via oVirt
