I think that the challenge of how to update the cpu tuning for all existing running instances is solvable.
a) quota:cpu_* is an additional property for a flavor and as such can be updated (applying to new instances created). b) Using the virsh tool, its possible to live set the scheduling tuning on a running instance - for example: sudo virsh schedinfo instance-0008905c --config --live --set cpu_shares=2048 That obviously needs tailoring for the actual running environment/instances. That does not however deal with the in-balance between instances created before and post update with no flavor extra-specs defined. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1978489 Title: libvirt / cgroups v2: cannot boot instance with more than 16 CPUs To manage notifications about this bug go to: https://bugs.launchpad.net/nova/+bug/1978489/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
