Thread-topic: about hot plug issue
Yeah, in fact, the script is quite simple, and it is just 
trying to create many VMXs or XENUs at the same time.
Another issue we found is that windows guest are not adapt with 
the new timeout value.


xm vcpu-set 0 1
sleep 5

xm cr config.vmx1 &
xm cr config.vmx2 &
xm cr config.vmx3 &
xm cr config.vmx4 &
xm cr config.vmx5 &
xm cr config.vmx6 &
xm cr config.vmx7 &
xm cr config.vmx8 &
xm cr config.vmx9 &
xm cr config.vmx10 &
xm cr config.vmx11 &
xm cr config.vmx12 &
xterm -display :1 -e "xm cr -c config.xenu1" &
xterm -display :1 -e "xm cr -c config.xenu2" &
xterm -display :1 -e "xm cr -c config.xenu3" &
xterm -display :1 -e "xm cr -c config.xenu4" &
