[libvirt-users] Deploying libvirt with live migration

[Scott Baker]

I have two physical servers: Virt1 and Virt2. I'm setting up live 
migration with CentOS 5.5 between the two. I've done this by NFS 
mounting /etc/libvirt and /var/lib/libvirt/images on both servers. This 
is working well for me except for one thing.

I see the same list of VMs on each server (as expected), but each server 
(Virt1 and Virt2) are able to start the same VM at the same time. This 
obviously causes IP conflicts and thrashes the disk image. Is there a 
way to tell my VM "cluster" that a VM is only allowed to be opened on 
one host at a time?
