Moving vm from one pool to another

[Nathan-plug]

Hi all,

I am using kvm and have ran into an issue I have on KVM host that is in 
desperate need of some TLC and I would like to migrate the VMs to 
another host.  The problem I ran into is that I set up an NFS mount on 
both KVM1 and KVM2 hosts (as instructed by every site I have come across 
on the subject) however, the pools that actually contain the running 
guest machines are different on both hosts and no image is currently 
sitting in the NFS shared pool.  If I understand it correctly, in order 
to migrate a running vm from one host to the next the vm must be in the 
NFS share so if that is the case, I need to know if there is a way to 
move a live guest from the local pool to the NFS pool?
