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.
