Yes, that's what I use, a RS-232 to USB adapter. I've connected the
adapter to either a laptop or a Raspberry Pi. As long as you have the
drivers it doesn't really matter what you use on the other end.

Keep in mind the cable between both boxes must be a null modem cable,
or else it won't work.

Xen uses the multiboot protocol, which is an OS agnostic standard
likely to be implemented by many bootloaders.

Also Xen can be build as an UEFI binary (PE), thus being booted
directly from the UEFI shell much like FreeBSD first stage loader.
