So I could have a domain with 100HZ, and another with 1000HZ? That would
be nice.

Which would be the clicks and pops I hear :)

I'm only testing VoIP as a proof of concept idea, and have been doing
some coding on kernel stuff, which is where xen is great. Even though
it's remote I can reboot a crashed domain easily, and have yet to
completely hose the domain by doing something stupid with a pci device
mapped to the domain.

Just on that subject, under what conditions would a domain with
permissions to access a pci device be able to bring down the machine if
I did something stupid in the kernel driver?

Thanks

James
