hi I am trying to do an installation of 64 bit HVM from a CDROM, the Dom0 is 64 bit. I am getting "pae not supported" !!

(as a side note, failure on RHEL 5.2 is different 'long not supported on your cpu, use a 32-bit version' .. cpu is 64 bit AMD and so is Dom0)

Do I need to tweak anything ?

Thanks /Jd
