I'm building a new Athlon X2 dual core machine specifically to use F7 as the physical host for two virtualized Windows Server 2003 installations. One will be my Active Directory domain controller, the other my SQL Server 2005 database server... anyways, a few questions:

1) Is the Xen version included with F7 the "express" version listed on XenSource's website? http://www.xensource.com/products/
2) And if so can I assume dual core will work just as well as two physical CPU sockets? They both use same SMP kernel right?
3) I want to run F7 using AMD's 64-bit extensions. The virtual environments are still 32-bit though, right? Which is what I want since 64-bit Windows is a real pain in the !@#$.

TIA

This page applies to Fedora Core 6 and Fedora 7 as well. Specifically your question about 32/64-bit is answered in the chart at the bottom.

Thanks for reply. I finally got the system built today.

Everyone is saying that for full hardware virtualization KVM is a better choice. Para-virtualized Xen hosts are definitely faster, but since I specifically want to run Windows that's not an option. So guess it's time to learn something new.

FYI, apparently Xen and KVM use the same GUI tools.

Here's a screenshot showing Xen para-virtualization:

And here's one I just took showing KVM full hardware virtualization:
