Limited to only a few supported OSes though. Performance is far better than VMWare, especially with modern hardware that supports hardware virtualization extensions.

Is the limited OS support for the guest or host OS?

Both....but...it's hard to describe int eh Host case. The way Xen works is that you boot up the Xen system, then Xen boots up one or more "domains". Dom0 is where all the I/O and other hardware access gets directed through. Dom0 support is limited to Linux, and a nascent OpenSolaris implementation. The Xen kernel itself is a Linux kernel, though I think the OpenSolaris and FreeBSD guys are working on a full implementation.
