Being relatively new to SMP, does diabling apic prevent the use of SMP?
I have not defined 'vcpu' yet xentop is reporting that there are 2.
I'm finding all functions OK so long as I set noapic.
The problem exhibited when apic was enabled was with the onboard bge-driver
based network card (watchdog timer resetting ... blah blah).
Other than that, a mknod for the missing device and installing the XML
parser has got everything up and running.
One other question, does the DOMU_INSTALL kernel require access to the cdrom?
and if so, can it be emulated sufficiently with a built iso-image used in
place of a physical device?
Thank-you very much for your help. I can't wait to see this port mature and
I'm sure I speak for more than my self when I say your hard work is greatly
appreciated.
