Hi Jeremy, I''m now working in a Xen-based project where some drivers in the Dom0 kernel (based on Linux 3.0) refuse to work with PAE. Do you know if it is possible to run 3.x kernel as non-PAE dom0 on Xen (any version is ok)? If so, how can I make it work? Many thanks in advance! Best Regards Junjie Mao

Many thanks in advance!Modern hypervisors support only 32-bit PAE PV and 64-bit PV guests (along with HVM guests in any mode). dom0 must be a PV guest and therefore must be either PAE or 64-bit. I''m afraid there is no option for a plain 32-bit PV guest. I suggest that you either fix your drivers (which are clearly very broken if they care about PAE vs non) or switch to a 64-bit dom0. Ian.
