In KVM you have a main thread leader, with each VCPU as a separate thread. When you pin a VCPU, only the corresponding VCPU thread is pinned. The main KVM thread leader remains unpinned. So if you query with taskset, make sure you look at the VCPU PID, and not the main KVM thread leader PID Daniel -- |: http://berrange.com -o- http://www.flickr.com/photos/dberrange/ :| |: http://libvirt.org -o- http://virt-manager.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: http://entangle-photo.org -o- http://live.gnome.org/gtk-vnc :|
