I wrote about this a couple months back. George asked me to submit to the Xen developers list, but I never had the time due to work demands on getting the new server set up. In my case, I had to use a different server. The new motherboard/CPU had no issues with the second CPU. If you turn off and unplug the second CPU, it will work.
This is a bug that was fixed on the development branch in December; a fix is included in the recently-released 4.6.1. I'm testing 4.6.1 packages now, they'll probably hit mirrors in a day or two.
