Konrad

Just one box but I'm willing to try more things.
A shame this is otherwise a really nice box for the price.
I sent Supermicro another email with updated info.
I'm not holding my breath :-(
They did fix the ipmi firmware for me so I guess I can hope for a fix.

In my last test shouldn't dom0_vcpus=2 have been dom0_max_vcpus=2?
Dom0 still has 16 cpus.

I'd prefer not pining dom0 but stability is more important :-)

Thanks for all the help so far.

John
