I can't make any statement regarding a comparison between Xen and KVM on
a Raspberry Pi, as I have no experience using KVM (on any platform).

However, I can say that to get Xen running on a Raspberry Pi 4B (using
Debian, not Raspbian, and UEFI->Grub bootloader), I needed to build Xen
myself with ACPI enabled. This was discussed very recently on this list.
Once I figured out how to build Xen (with help from Julien),
installation and setup was fairly easy and not really different to a
installation with a package manager. I needed to manually enable some
services, but that's the only big difference that I remeber.

If you use U-Boot as a bootloader, you should be able to use the
standard Xen packages provided by Debian (I didn't try that out myself).

Xen has been running flawlessly on my RPi since installation a couple of
days ago.
