Hi Matt, you are right. That's at least what I understand under 'live-evacuate'. The compute is still working, all VMs on it are running. Our VMs can all be live-migrated. We wrote a script to live-migrate all VMs to other computes, to do hardware maintenance on the evacuated compute server.
I know, this is not going to work for every setup, but could be starting point, for what Gilles described. Matt Riedemann <mriede...@gmail.com> schrieb am Mo., 30.
