["Jürgen Peter" <Juergen.Peter@xxxxxxxxx>]

Hi,


here another Matrix, hopefully correct, which includes PAE.

Hypervisor  dom0        domU(PV)               domU(HVM)

32-bit      32-bit      32-bit                 32-bit

32-bit PAE  32-bit PAE  32-bit PAE             32,- or 32-bit PAE

64-bit      64-bit      64-bit or 32-bit PAE*  32-, 32-PAE or 64-bit 

Jurgen
