I'd suggest you look at hardware virtualization (HVM), as then you'll be
able to use which ever kernel you need to use. With a paravirtualized
guest, you can only use a kernel that's had the Xen patches applied, so
you won't be able to use a standard SMP kernel. In order to do hardware
virtualization, you'll need a CPU that can handle it. Google/Wikipedia
should be able to help you find one. If you cat /proc/cpuinfo and look
for VMX (Intel processors) or SVM (AMD processors), that will tell you
if you already have the capability for hardware virtualization.
