I think you need to set the number of CPU's when you create the BIOS in
3.0.3. 3.0.4 will have dynamic settings for number of CPUS... But I
could be wrong on that.

Make sure you set PAE=1 in your config file for the domU. Long Mode
requires PAE to be set, and if you tell the HVM domain that you don't
want PAE, then you don't get Long Mode either.
