The machine needs to have the hardware assist virt bits on the chip. 
Check BIOS. AFTER changing in BIOS, you need to turn off the machine (I 
pull the plug to be sure) and turn it back on. A 'soft restart' doesn't 
get the BIOS change for virt I have learned, the hard way.

MOST machines that are server quality and less than 3 years old, have 
the bits. For desktops or older, it is hit or miss.

IIRC you MUST be 64bit also. You can run a 32bit guest, but 64bit host 
is needed. I maybe mis-remembering though.

that could work. performance might not be as good.
