~/git/qemu$ x86_64-softmmu/qemu-system-x86_64 -m 2048 -drive if=virtio,file=iscsi://172.21.200.45/iqn.2001-05.com.equallogic:0-8a0906-9d95c510a-344001d54795289f-2012-r2-1-7-0/0,format=raw,cache=writeback,aio=native -smp 2,cores=2,threads=1,sockets=1 -cpu 
host -monitor stdio -vnc :1 -enable-kvm -usb -usbdevice tablet -vga cirrus -global virtio-blk-pci.scsi=off  -serial null  -parallel null -boot c

With just -smp 2 it works. However, have a look at my other email I think there 
is a bug in smp_parse, because -smp 2 yields cpus=2,cores=1,threads=1,sockets=1 
whereas I think cores should
be 2.
