Good day.
As of Qemu 0.8.0[0] does it support SMP. When trying to boot Plan 9 on it,
with two processors, then there appears the message:
panic: lapic clock faster than cpu clock
After removing that check and with 255 processors did it only find 8 cpus
and dumpstack because of divide errors.
The apic clock problem seems to be Qemu[1], because I still want a 42Ghz
cpu in userspace.
Sincerely,
Christoph
