I'm not certain you got the relevent changeset; the "xen/stable" branch now has it, but I think I only updated it yesterday. xen/stable is now 2.6.32.10.


Still many small hiccups in Dom0
One time (i think after HVM DomU creation) i get:
"hrtimer: interrupt took 4045137 ns" in Dom0 dmesg

That's only 4ms.  Not great, but not too bad.

I also upgraded to newest xen-unstable:
xen_changeset          : Wed Mar 17 09:18:34 2010 +0000 21041:066c3eead6ec


Could it be that the missing HPET is causing all this trouble? I just noticed
that in "xm dmesg" :

(XEN) CPUIDLE: disabled due to no HPET. Force enable with \047cpuidle\047.

I don't bother really about CPUIDLE, but i should perhaps about HPET ?
Is there a reason xen doesn't enable HPET? Motherboard is Intel DX58SO

I don't think that will be relevent.
