Hello,
I've heard that KVM-33 now supports SMP hosts and SMP guests,
which is cool. However I do have some newbie-level questions
about this one.
- I assume this is implemented by using n threads for n CPUs/CPU
cores and letting the host OS schedule accordingly? Or does the
VM somehow automagically bind each of its virtual CPU threads
to one of the host CPUs/cores?
- I'd be interested to learn how to actually use SMP ;-). What
options do I need to enable inside the guest kernel's menucon-
fig beyond the basic SMP one, specifically what SMP sub-archi-
tecture type?
- For that matter, which Processor Family option is appropriate
inside KVM? I've been using "Pentium III" so far. Should I be
using the family of the host system?
- How do I tell the VM to use multiple CPUs/cores? Some command
line arguments to qemu-system-x86_64, or another way?
Thanks for reading,
Peter
