This depends on how you define "run fine". Virtualbox and VMWare have kernel 
modules (that is, if you can compile the VMWare ones for the latest kernels) 
that will enable decent performance on non-virtualized CPU. QEMU doesn't have 
it, and will typically be extremely slow.

For Intel this is a hit-or-miss thing, there was an earlier thread where I 
ranted about it quite a lot.

Best, :-)
