When we try to do:
vol = conn.storageVolLookupByPath(disk['alias'])
e.g:
vol = conn.storageVolLookupByPath('/opt/wiki-uat/mediawiki-uat.img')
Libvirt raise an error:
"libvirtError: Storage volume not found: no storage vol with matching path"

e.g.: '/opt/wiki-uat/mediawiki-uat.img' is not exists
Please look if the path exists (via the host that the Libvirt Domains exists).

Hi Shahar ,

vdsm shows the following errors.

Just giving the background how do we created VMs in KVM,  All the VMs are created on separate Luns of 100 GB and before creating VMs in KVM we usually format the LUN and then we create VMs on the formatted Lun.In this case we have mount the formatted Lun under "/opt/wiki-uat".

I am just curious to know , will this type of VMs can be imported in Ovirt.

Sorry for the miss leading message, its suppose to say that some of the selected VMs cannot be imported.
This can be due to broken storage disk path or any other Libvirt parsing error.
For more details you can look at the vdsm log (/var/log/vdsm/vdsm.log) and see why we failed to parse Libvirt xml for each VM that is not in the right list.

Hi Team,

While importing VMs with external Provider KVM on my oVirt setup, i am getting the below error:

"All chosen VMs couldn't be retrieved by the external system and therefore have been filtered. Please see log for details.

As per Shahar suggestion yesterday i was able to view the virtual machine of my KVM hypervisior in oVirt Portal.I have also created the export domain in my DC as well.

Any idea how to resolve this issue and so that i can start importing VMs

when you run virsh you where logged in as root user,
the user that oVirt is running is vdsm

you need to run:
$ sudo -u vdsm ssh-keygen
$ sudo -u vdsm ssh-copy-id user@kvmhost

you can look at wiki we have for Xen to generate the ssh keys but its the same for kvm.

Hello Folks,

I am trying to import KVM guest VMs to my oVirt Server using external Provider. But when i add external provider with type KVM and do the testing that time i am getting below error

Caused by: org.ovirt.engine.core.vdsbroker.vdsbroker.VDSErrorException: VDSGenericException: VDSErrorException: Failed to GetVmsNamesFromExternalProviderVDS, error = Cannot recv data: Host key verification failed.: Connection reset by peer, code = 65

I have already configure password less authentication with ssh keys between proxy host to my KVM hypervisor. Though i can reach to kvm hypervisor with virsh connect.

[root@lplinnd1hypov13 ~]# virsh -c qemu+ssh://root@<KVM-HYP-NAME>/system
Welcome to virsh, the virtualization interactive terminal.

Type:  'help' for help with commands
       'quit' to quit

virsh #

Any idea how to resolve this issue, so that i can add KVM as external provider and  start importing my KVM guest VMs in ovirt setup


Thanks in Advance
