[kolla] Updating libvirt container images without VM downtime

I'm looking for validation regarding the way Kolla and containers work 
in regard to upgrading the libvirt containers. Essentially, when you 
upgrade the libvirt container to a new container image, the container 
needs to be restarted, thus creating downtime for the VMs. There is no 
way to avoid this downtime, unless you migrate the VMs to another node 
and then move them back once the container has restarted, right?
