I was under the impression that if the CPU has native virtualisation
support (Intel Core 2 Duo or higher and pretty much all AMD AM2 socket
CPUs) then Windows would run on Xen. As far as I can remember Windows
won't run on Xen if the CPU doesn't support virtualisation (so that
rules out Celeron Dual Core and Pentium Dual Core).

I've got VMWare Server running on my Ubuntu box (Phenom X4 9600, 4GB
Ram) and it runs Windows 2003 Server and SQL Server fine, although
saying that, they're small test boxes. I believe I don't have
virtualisation turned on in VMWare by default but it runs okay.

Thanks for everyone's replies thus far. We use Vmware GSX at the moment (ESX being free though now, albeit cut-down), and while it runs MS with SQL fine, we had repeated issues with the database corrupting. I suspect this was down to I/O stress, or hardware/firmware, which is difficult to 'prove'.
