Hi Avi,

The command line is created using libvirt 0.7.5 (compiled by me) and 
looks like this:

/usr/bin/kvm -S -M pc-0.11 -enable-kvm -m 512 -smp 1 -name winxp -uuid 
f99c79b6-2706-dff0-af5c-cea53559f89c -chardev 
socket,id=monitor,path=/usr/local/var/lib/libvirt/qemu/winxp.monitor,server,nowait 
-monitor chardev:monitor -boot c -drive 
file=/home/images/winxp.raw,if=ide,index=0,boot=on -net 
nic,macaddr=52:54:00:c4:90:94,vlan=0,model=rtl8139,name=rtl8139.0 -net 
tap,fd=41,vlan=0,name=tap.0 -serial none -parallel none -usb -vnc :5 
-vga cirrus

While the host /proc/cpuinfo contents look like this:

demo-laptop:/home/images# cat /proc/cpuinfo

I may also be able to arrange for remote SSH access into the box - mail 
me off-list if you are interested.


HTH,
