Hi! I'm complementing this post:

I'm trying the following command:

nova live-migration MY_UUID_VM_INSTANCE my_host_destine

And I'm getting the following error in /var/log/nova-all.log:

File "/usr/lib/python2.6/site-packages/nova/virt/libvirt/", line 4162, in pre_live_migration
   self._create_images_and_backing(context, instance, instance_dir,

UnboundLocalError: local variable 'instance_dir' referenced before assignment

I do not know what I have to do. I've put password less between my hosts, and I 'already' can do 'migration' in the dashboard, but no live-migration. I'm using VirtualBox CentOS VMs. Someone could help me? Thanks in advance.

Can you check if anything shows in libvirt's log file?
