Are you saying that even with correctly running ntpd in both dom0s the
migrated domU will see a timejump? A small jump forward is expected
because the domU goes through a suspend/resume cycle while the last
pages of dirty memory get transfered. I would be surprised if
independent wallclock can change anything in this regard.

Well, yes. This was the case several years ago. As the problem disappeared with
the use of independent wallclock, we did not investigate in later releases.
To summarize the takeaway from this thread: The independent_wallclock control
does not exist in the pvops kernel. If absence of this control causes problems,
please enter a bug with the details.

You should update your documentation then.
Yep. If you care to contribute to openSUSE, patches welcome :-).
