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.<br></span></span></p><p style="padding: 0; margin: 0;"><span data-mce-style="font-size: 10pt; font-family: tahoma,arial,helvetica,sans-serif;" style="font-size: 10pt; font-family: tahoma,arial,helvetica,sans-serif;"><br data-mce-bogus="1"></span></p><p style="padding: 0; margin: 0;"><span data-mce-style="font-size: 10pt; font-family: tahoma,arial,helvetica,sans-serif;" style="font-size: 10pt; font-family: tahoma,arial,helvetica,sans-serif;">Check the archives for my e-mail address and see George's replies.
