Hi Andrija, We experienced that problem with stock packages on CentOS 7.4. Live migration would frequently fail and leave the VM dead. We since moved to RHEV packages for qemu. Libvirt is still stock per CentoS 7.6 (4.5). I want to say the situation improved but I can't tell yet if we have a 100% success rate on live migrations (as it should be !)
Redhat also have been messing up severely with stock libvirt versions between 7.4/7.5/7.6 in such way it broke live migration compatibility (cpu definitions). Im at the crossroads right now to entirely ditch centos/redhat in favor of Ubuntu to have well tested stock packages. best, -Jfn On Thu, Nov 21, 2019 at 5:25 PM Andrija Panic <andrija.pa...@gmail.com> wrote: > Hi guys. > > I wanted to see if any of you have seen similar/same in master, as below. > > I've been testing some work/PRs (against the current master) and I've seen > that VMs will crash/be stopped occasionally when live migration is > happening.
