[CentOS-virt] CentOS 5.2 (x86_64) : 64 bit HVM VM fails.

[jd]

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
