It's been a while since I looked, but IIRC there are two ways to run Xen:

1. You boot the Xen kernel, which is a modified Linux kernel. It does
all the I/O and driver stuff. Guest machines require a modified kernel,
which IIRC only exists for Linux.

2. If you have the Intel or AMD virtualization-enabled chips, you boot
the Xen kernel and it can then boot and OS with an unmodified kernel.
This works for at least Windows and Linux, but I don't know about MacOS.

In any event, the drivers in mode 2 are the guest OS drivers, so it
"should work".
