> are the guests SMP?

They are all SMP capable (default -xen kernel config), but except for
one they are all running with 1 vcpu.

> What does 'xm list' show about the relative CPU burn rates?

As I only rebooted recently I don't have any actual figures, but Dom0 is
highish (which makes sense as it was doing a compile), and DomU was low.
Neither had unexpected values in them.

If you can give me the syntax for rolling back to a specific changeset
or time (or I can look it up, but I'm sure you'll know it off the top of
your head :) I can start a binary search on when it all went wrong, and
definitely confirm that the problem didn't exist earlier.
