For PV guests it doesn't matter.  For HVM guests, the CPU has to support 
it (and it may need to be enabled in the BIOS).  You should find the 
following flags in the /proc/cpuinfo output if your CPU supports 
hardware virtualization.
cat /proc/cpuinfo

Intel: vmx
AMD: svm

The other rule of thumb is that all Socket F Opterons support HVM and 
all AM2/AM3 Athlon64s support HVM.  The old socket 939/940 chips 
generally did not support HVM.
