Did a bit more testing. I open a connection to the hypervisor from
python using:
con = libvirt.open('qemu:///system')No call that I tried on con returns while a migration is in progress. I tried: listDomainsID, lookupByID, getInfo, getHostname, getType. This sort of combines with my other outstanding email, about how to use migrateSetMaxDowntime. If I can't even get a domain object for a migrating domain, how could I possibly set max downtime AFTER the migration has begun? I must be missing something crucial. Can someone please give me some wisdom? --Igor On Fri, Dec 17, 2010 at 02:06:27AM -0600, Igor Serebryany wrote: > Hi, > > I am running libvirt 0.8.6 on qemu (kvm, really) 0.12.5.
