[one-users] live migration fails on ubuntu 11.04

[samuel]

Hi folks,

After few tricks to the standard configuration (controller exporting via NFS
opennebula directories to 2 other nodes) seems to work except for one point:
live migration.

When starting live migration (from sunstone web interface), the following
problem appears:

Tue Jun  7 17:12:51 2011 [VMM][I]: Command execution fail: 'if [ -x
"/var/tmp/one/vmm/kvm/migrate" ]; then /var/tmp/one/vmm/kvm/migrate one-131
node1; else                              exit 42; fi'
Tue Jun  7 17:12:51 2011 [VMM][I]: STDERR follows.
Tue Jun  7 17:12:51 2011 [VMM][I]: error: Requested operation is not valid:
domain is already active as 'one-131'
Tue Jun  7 17:12:51 2011 [VMM][I]: ExitCode: 1
Tue Jun  7 17:12:51 2011 [VMM][E]: Error live-migrating VM, error: Requested
operation is not valid: domain is already active as 'one-131'
Tue Jun  7 17:12:51 2011 [LCM][I]: Fail to life migrate VM. Assuming that
the VM is still RUNNING (will poll VM).

I'm using qemu+ssh transport with the following version:
$ virsh version
Compilado contra la biblioteca: libvir 0.8.8
Utilizando la biblioteca: libvir 0.8.8
Utilizando API: QEMU 0.8.8
Ejecutando hypervisor: QEMU 0.14.0

Installed version of open nebula is 2.2.

Could anyone shed some light on this issue? I've looked in the Internet and
found some posts relating to qemu bugs but I'd like to know whether can I
get more information about this issue.

Thank you very much in advance,
Samuel.
