The hypervisor for itself does, and for HVM guests they're supported
too (and then equally for the upcoming PVH ones).

There's an optional feature (of unknown quality) to also allow the use
of huge pages in PV guests (requiring at least a balloon driver in the
guest that's aware of this), but personally I'd recommend staying
away from that.
