I posted a comment some time ago about that. If you do not mount the cpuset controller, i.e for RHEL 6 you delete the cpuset line from /etc/cgconfig, the CPU affinity isn't controlled by cgroups any more but uses the old mechanism, which works as expected: take a host CPU offline and it will be removed from the process CPU mask and will show up again after onlining the host CPU. The only issue I currently see is that the display of virsh vcpuinfo and vcpupin is somewhat strange. Using taskset will however show the the correct affinity. I suggest that you try out that approach.
I saw your comment before. You are quite right. :) But the situation here is there are some other features in libvirt using cpuset. For example, emulator-pin feature. If we remove cpuset in the system, other features could be unusable. And more, I found different cgroups are widely used in libvirt now. I don't think removing cgroups from system is a good enough idea, though it can be a work around. What do you think? :) Thanks. :) -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
