[Users] Importing from KVM

Hello all, I'm trying to import VMs from a Centos5/KVM host to ovirt using virt-v2v. I used this command: virt-v2v -ic qemu+ssh://root@virthost1.mydomain.local/system -o rhev -os virthost3.mydomain.local:/exports/exp --network ovirtmgmt test.mydomain.local It works, but the resulting OVF file cannot be read by ovirt-engine ("Failed to read VM '[Unknown name]' OVF, it may be corrupted"). I had to edit the OVF file, removing the NIC Item worked, but restoring the imported VM fails. Looking at logs, I found a PostgreSQL constraint violation on an insert (sorry it's in French) "Caused by: org.postgresql.util.PSQLException: ERREUR: la valeur d une clé dupliquée rompt la contrainte unique « pk_vm_device » Where: instruction SQL « INSERT INTO vm_device( device_id, vm_id , device , type, address , boot_order , spec_params, is_managed, is_plugged, is_readonly) VALUES( $1 , $2 , $3 , $4 , $5 , $6 , $7 , $8 , $9 , $10 ) »" Looks like there's a primary key violation (duplicate) on insert. I have two questions: - what's the minimal OVF file that can successfully import a VM? - are 'default devices' created if they are not in the OVF file? (would explain PK violations) oVirt is very impressive and stable, deploying was a breeze, but it"s difficult to understand why it is so hard to move VMs from a libvirt/KVM host (which is basically the same architecture). Am I missing something? Thanks Alex Drahon
