[Users] v2v error

Tue May 7 06:33:49 UTC 2013

Hi,
I had the same problem some weeks ago. After many hours of try an error 
I went another way.
I made a new VM on the ovirt engine with the same parameter than the kvm 
VM. Especially the "Allocation Policy" of the virtual disk is important 
(Preallocated for raw images and Thin Provision for qcow images). Then I 
export the VM. Then I copy the image from the KVM server to the ovirt 
export folder and override the empty one. Please check the permissions. 
Now you can import the VM.
I go this way with a lot of linux and windows VMs.

Regards,  Michael
