Yes, you will be able to run XEN/PV guests on old CPUs without VT nor 
SVM.  However, for that, you will need your guest to have a PV-capable 
kernel.  You can use either Direct Kernel Boot (kernel=) or pvgrub2. 
You can even run a general and multi-purpose Linux kernel designed for 
that matter, and run various types of guests within your farm or host, 
as long as you also deliver its related modules into `/lib/modules/`.
Note however that 32-bit PV has already been deprecated and the hype is 
going towards PVH.
