Comment 12 Cole Robinson 2013-04-01 20:32:48 UTC 
Unfortunately I think hotplugging cpus is just one of those things that doesn't work with F18 vintage qemu. Upstream is just finishing up the infrastructure now as I understand it.
Comment 13 Cole Robinson 2013-07-11 21:18:48 UTC 
Just closing this as cantfix for F18 since it will likely never be fixed there, trying rawhide is probably more interesting.
