Some xen questions

Some xen questions

[Sébastien RICCIO]

Hi,

Some dumb questions for the ones that have time to answer them :)

I am currently testing xen unstable on a two quad-core dell server.

What would be the best settings from dom0 kernel config ?

- Preemptive kernel (deskop or server) ?
- 100, 250, 1000 Hz ?
- Is there a way to easily build 32 and 64 bits domU kernels from
  the same xen source directory, without messing up each other settings ?

Thanks a lot for your answers !

Best regards,

If you get any choice on these (I thought we hardcoded them) then voluntary
preemption and 100Hz should work well.

At least in xen-unstable we now build outside the Linux source tree so you
can have separate builds for different architectures co-existing happily. I
think this may have been added after 3.0.4 however.
