Dear all,
With latest qemu 0.9.0, the -smp 2 doesn't work. guest os never sees
more than one CPU. I am running suse 10 on host and redhat el4 on guest
. Tried several attempts and seems doesn't work.
I lookup some pcbios code, it seems bios attempt to read address 0xf000
for num cpus, but not find in hw/pc.c or vl.c that deal with this
address . Is there are a problem on number of cpus not passing to the
bios of vm correctly?
regards,
David Chow

Hi all,
Does anyone have any success in SMP? because I saw many people talk
about it in the list but personally no success on it. Any help will be
appreciated. Thanks.
