But I also plan to add a test-4 on a machine with a cpu that was hot-unplugged, to show an instance where CPUs is less than maxcpus, so I can make those changes in my patch. Which means I'm fine with your patch going in, as-is. ACK. -- Eric Blake eblake@xxxxxxxxxx +1-919-301-3266 Libvirt virtualization library http://libvirt.org
