You are right, I was still running xen-utils-common 3.3.1-2, building
and setting-up 3.4.2-3 solved it. In the control file of xen-3-3.4.3,
there is:

Package: xen-utils-3.4
Depends: xen-utils-common (>= 3.3.1-1)

can you guys change it to (>= 3.4.2) so that I'm the last one to have
this issue?

Just a bit of feedback now: I've been running Xen 3.4.2 on my laptop for
few days now (without xend, but still under Xen), and I have a very
snappy feeling: my desktop seems to run as fast as when running without
Xen, which was not at all the case last November when running 3.3.1 and
the pv_ops dom0 patch of the time.

Cheers,

Thomas
