I'm still using nfsv4 so far, still haven't tried with nfs3. I will give it shot on monday though.

Re: [Openstack] 答复: [OpenStack][Nova] Live Migration + NFSv4 - Permission issues
@Romi, check if the libvirt-bin is running, that usually means its not.
So i've managed to get my instances to launch, thx Mandar!
However, when i try to migrate i get this error:
2012-07-05 09:33:48 ERROR nova.manager [-] Error during

Any ideas on how to debug solve this?
