Yes, due to a bug elsewhere in the code I ended up with an LXC container in the / cgroup. When killing the container libvirt recursively kills all processes in the container's cgroup. When the cgroup is / this is all processes on the host until it kills itself :-) I now have a 30 mile journey to the colo to reboot this machine since I have no remote power control on it :-) 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 :| -- libvir-list mailing list libvir-list@redhat.com https://www.redhat.com/mailman/listinfo/libvir-list
