Xen devel - Jan 2011 - expects freq 1800MHz but host''s freq is 1800MHz: trap and emulate rdtsc

When I restore a DomU I get:

(XEN) save.c:72:d0 Domain 510 expects freq 1800MHz but host''s freq is
1800MHz: trap and emulate rdtsc

I''m using an earlier 4.0.2 rc but I can''t see any changes to
save.c
since then.

Is this a problem?

Thanks

James

This warning no longer corresponds to what the code actually does.
