Well, they do (as long as no one has gone and broken something in the
chain) in unstable, but not for currently available released versions.
3.0.5 should (we hope) have fully working save/restore functionality,
but there are some interesting challenges when the guest is busy writing
to the disk or networking at full pelt when it's being saved
(outstanding and incomplete IO requests is the worst part of that
problem). I'm currently testing Save/Restore more or less daily,
reporting whatever problems I see back to XenSource, as does some people
at Intel.
