Question is: How does ticklessness effect audio? Realtime-preemptive kernels?
Other multimedia?

It's not just about power -- NOHZ (also called tickless kernels) can

But this all is just in theory.
Indeed, using a tickless Linux kernel as _guest_ induces less overhead
since there are less world switches between the host and the guest.

I'll try the above.
Just to follow up, passing the above kernel parameter solved the
problem. I read up a bit on CONFIG_NO_HZ=y and this is a good thing
to save power. If I get a chance, I may try the latest svn snap ..
