Use the xen-hypervisor-3.0-i386-pae package, instead of

It failed saying my kernel isn't pae.

Isn't PAE for 32 bit systems anyway ? I understood 64 bit systems didn't
need it (provided they have a 64bit kernel)
I'm just trying to avoid useless overhead.

Aim is to get 64 bit OS virtualised, don't I specifically need dom0 to
run 64bit to do that anyway ?
