[one-users] Problem with Migrate Opennebula +kvm

[Ruben S. Montero]

Hi Sergio,

You may have problems with the last version of Ubuntu (9.10) and
apparmor. The default configuration of the qemu-libvirt files prevents
the daemon to write checkpoint files under $ONE_LOCATION...

If you are using Karmic follow slide 47 of [1]. You should apply that
to all the cluster nodes.

Cheers

Ruben
