Hello Ian, 

in a xen-users post from October [1] you state that the
time-went-backwards issues you experienced went away as soon as you
changed the clocksource to jiffies in Domain0 *only*.  (system was a
Dual-Core Opteron)

Were all you Domain-Us single-VCPU-based, or did they have more than 1
VCPU?

I'm asking because I had a time-went-backwards problem with some old
version of Xen-3.0, and as soon as the second CPU core was turned off,
it went away.  Therefore I suspect there might be some correlation
between needing clocksource=jiffies and multi-/single-VCPU-based
systems. 

Regards,
Milan
