I'm running Windows Virtual PC (RC) on a Windows 7 (RTM) 64-bit host. When I create a new virtual machine and try to install 64-bit Windows 7 on that VM, I get "this CPU is not compatible with 64-bit mode."
Is there a way to create 64-bit virtual machines?

Windows Virtual PC does not support 64-bit guests. You may want to look into VirtualBox or VMware. You may also want to see the answers to the similar question on Server Fault.

VirtualBox website says "VirtualBox is a general-purpose full virtualizer for x86 hardware" and makes no claim for (Intel) x64 architecture – Rowland Shaw – 2009-08-24T16:28:53.823

@Rowland, do some research: http://www.virtualbox.org/wiki/VBox_vs_Others
– John T – 2009-08-24T16:37:43.493@John T that only says "64 host OS support" - it doesn't specify which 64 bit architecture it supports (x64 or ia64, etc.) – Rowland Shaw – 2009-08-25T07:47:44.550
1@Rowland, you aren't even looking for the right thing. A VM is considered a guest, not a host. – John T – 2009-08-25T15:57:20.763
"Windows Virtual PC" is the product name, so that's why I used that as the tag. – CoderDennis – 2009-08-23T19:38:07.580
1I found this odd myself, especially as there is separate x86 and x64 installers... – Rowland Shaw – 2009-08-24T16:24:33.863
After I asked this question, a duplicate was added to superuser via migration from serverfault. http://superuser.com/questions/28043/64-bit-guest-oss-virtual-pc-rc-on-windows-7
