On 32-bit Xen all the PV guests have to match Xen. So if Xen is PAE then dom0
and all domUs must be PAE. If Xen is non-PAE then dom0 and all domUs must be
non-PAE. You can't mix PAE and non-PAE.
On 64-bit Xen, PV guests (including dom0) can be 64-bit or 32-bit PAE. 32-bit
non-PAE PV guests won't run.
HVM guests can have any memory mode "equal or less than" the Xen memory mode.
e.g. 32-bit non-PAE only on 32-bit non-PAE Xen. 32-bit PAE or non-PAE on PAE
Xen. 32-bit non-PAE, 32-bit PAE, 64-bit on 64-bit Xen.
Hope that helps,
Cheers,
Mark
