Well, if it is a real issue and not just existing in the Lab with a very special machine (it seems hard to get one for you as well) then I can re-port the fix to the current version of Xenials Libvirt and you can retest with that.
Anything later is already fixed, but I'd ask you to confirm that to be sure. So next steps: 1. please test the same with e.g. Ubuntu 18.04 - is the bug fixed in there? 2. let me know if you still consider this important, then I'll prep a new build for Xenial to test (If it is not important we can mark it won't fix) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1709877 Title: CPU hotplug fails in the system with empty numa nodes, "Invalid value '0-1,16-17' for 'cpuset.mems': Invalid argument" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/1709877/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
