For running Linux machines, there's nothing wrong with using xen, and it
probably runs faster than hardware virtualization. For non-Linux I would pass on
emulation.
There's nothing wrong with it, I know a few web hosting operations which still
use xen. If Fedora supported xen I would probably use it on some available
hardware, I just don't feel like going back to the days of building and updating
my own kernels all the time.
