Well, the output was from the kvm where I tried to boot xen with the same config as on my rootserver, where I don't have access to the console output to see why it doesn't boot. :) > > So is this supposed to work with APICs? > > Yes.

Just tried it again just in case and it still doesn't boot if I remove the "noapic acpi=off" options. (And it seems to blow up before I get any output over netconsole) I should try it on my notebook I guess, though that is a Core2 Intel with Vanderpool IIRC, so it may behave differently there. > > APIC-support coming later? > > Never. There should be no need for it.
