You would have to set the priority of all vCPUs in each guest, as well as emulator threads in each guest (the latter needs very new libvirt).This does not seem a viable option then with Ubuntu 18.04. And changing XML on all guest VMs is extra work. Is there no other way? For example, are all such virtual machines not some daemon or systemd unit or set of units? Would it be feasible to lower the priority on all of those? Or is that not easy to do either?
I'm not sure if we're resetting all the cgroup values, so it should be possible by setting this for the machine.slice cgroup (or somewhere around there) which would make it effective for all the VMs, right? I have not tested it, though, sorry.
Thanks again, rdiez _______________________________________________ libvirt-users mailing list libvirt-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvirt-users
