[Qemu-devel] qemu -smp n, "n>1" will lead the guest OS get dead

[Wei]

Hi all,

 

I have met a difficult when I have installed ubuntu on qemu.

 

My physical meachine is 8 cores. 

 

Version of my qemu:

QEMU PC emulator version 0.12.5 (qemu-kvm-0.12.5), Copyright (c) 2003-2008 Fabrice Bellard

 

I use the following cmd to install ubuntu10.10 on qemu

    qemu-img create -f qcow ubuntu.img 6G

    qemu -m 1100 -hda ubuntu.img -cdrom ubuntu-10.10-server-i386.iso -boot d 

 

Then if I type

    qemu -smp 1 ubuntu.img

the OS can start normally

 

But if I type

    qemu -smp 2 ubuntu.img

the OS can reach grub(select OS), but then I can't reach the "logon:", It appeared that It got in a dead circle.

 

When I tried to set the value of option "-smp" more than 1, The guest OS will get dead.

 

Any can help?  Thank you very much!

 

BestWishes
