It looks like in their latest stable release they do, or at least I see
Xen kernels in my package tree, and the Debian wiki page on Xen still
appears to be active:
http://wiki.debian.org/Xen

Why? 

At the moment it doesn't seem as if KVM has the tooling and ease of
management in place to manage virtual guests. KVM might be a decent
virtualization tech, but I haven't seen the tooling yet that let's me
migrate a virtual guest from one server to another, which is important
in server environments.  And for environments currently using Xen the
migration path to KVM mightn't be that easy, for example Xen guests
wont' necessarily run on KVM without changes or new kernels. (Correct me
if I'm wrong, on any of this.)

If I'm looking for an Open Source low cost virtualization and Xen is on
it's way out, and KVM isn't quite here yet, what is one supposed to use?
