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.

Re: [CentOS-virt] c7 xen-4.6 crash.

[President]

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.



Check the archives for my e-mail address and see George's replies.  If you can 
follow through with reporting it, that would be great.
