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.

David
