Hi Michael, 

Thanks. One question, Myexported VM has the name Fedora, how can I identify it on the system? 
In the export domain i have 
drwxr-xr-x. 2 vdsm kvm 4096 Apr 12 17:07 dom_md 
drwxr-xr-x. 3 vdsm kvm 4096 May 7 10:57 images 
drwxr-xr-x. 4 vdsm kvm 4096 Apr 12 17:08 master 

and in 
/mnt/398da79f-53e1-43dd-8836-e58edd4de975/images/2a95635c-3e1b-45a6-be8c-fa66317b6475 
I have 
-rw-rw----. 1 vdsm kvm 1073741824 May 7 10:59 f89d8ca3-f65c-45a0-8f2e-df2f05014d0b 
-rw-r--r--. 1 vdsm kvm 269 May 7 10:57 f89d8ca3-f65c-45a0-8f2e-df2f05014d0b.meta

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

Assunto: [Users] v2v error 




I'm trying to export a VM from KVM. It's a Fedora14 machine. 

I run: virt-v2v -i libvirt -ic qemu+ssh://root@IP-Address/system -o rhev -os nfs.domain.local:/ovirt/export -of qcow2 -oa sparse -n ovirtmgmt VM_Name 



It starts to buid the umage but in the end I have an error message: 

virt-v2v: Failed to launch guestfs appliance. Try running again with LIBGUESTFS_DEBUG=1 for more information 



Something wrong with the guestfs? 



Jose
