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

Thanks for your help. I tried the import with a minimal OVF file as described by Shahar and it worked, but failed on activate. This time I have a constraint violation on pk_vm_static, which means that ovirt-engine doesn't create a vm_guid if it isn't here. I guess it's the same for a lot of parameters. To move forward, I'm going to create "shadow" VMs on ovirt-engine, export them and import my "real" libvirt/KVM VMs with the exported OVF files. Makes sense? Where should I look in the source tree if I want to (try to) actually help with the restore code for imported VMs? Alex On Thu, Apr 5, 2012 at 5:59 AM, Shahar Havivi <shaharh@redhat.com> wrote:

Of course it fails if ovirt-engine doesn't generate one.

I'm now back to my original error, integrity violation on pk_vm_device... if you are adding a device I assume that you need to generate a new GUID for it (or it will use a null one 0000:0000:000... and you will get primary key violation on the second device). if its not the case so maybe Eli can help, Eli do you know why Alex is getting the pk_vm_device?
in any way can you post the OVF?
