I would skip over those servers and look for something that has the VT
instruction set if you want to use them to run Windows on Xen. You can
do paravirtualization with Debian, but you won't be able to do the full
hardware virtualization with Windows. That is unless Xen supports
instruction rewriting now. I don't believe that it does, but someone
will correct me if I am wrong. ;-)

Here are the flags for my processor with VT. Or, you can go with AMD. The
flag for it is smx. I believe.

Here are the flags for my CPU. See the vmx flag?

flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge
mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe
syscall nx lm constant_tsc arch_perfmon pebs bts rep_good nopl pni
monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr lahf_lm ida
