Yes...if you look at the "xm dmesg" output, you should see one of the following
lines:
(XEN) I/O virtualisation enabled
or
(XEN) I/O virtualisation disabled
If you see the "disabled" version of the message, check your BIOS to see if it
just needs to be turned on. Also, if you see disabled, grab the model number
of your CPU and check the CPU specs to see if the CPU support I/O
Virtualization. I'm not sure about AMD, but Intel's site has very easy-to-read
specs for the CPUs that tell you about the various features they support.
