[Xen-devel] How does domain (smp) scheduling work?

[Chris Bainbridge <chris.bainbridge@xxxxxxxxx>]

Hi,

I'm curious about how the SMP support in Xen works. Is it possible to
have a SMP aware 2 vcpu domain running on both physical processors at
the same time? Can Xen schedule two domains at the same time, one
running on each processor? How about on a hyperthreaded kernel?

If one domain has a run away process (eg. fork loop) or bad device
driver, will it affect the running of other domains? I suspect it
does, as there are no resource guarantees. If I have a SMP or
hyperthreaded machine with uniprocessor domains, will other domains be
scheduled on the 2nd cpu if the first is being hogged by a runaway
domain?

Sorry if this has come up before, I've checked google and couldn't
find any answers.

Cheers,
Chris
