/usr/bin/qemu-kvm -S -M pc -m 512 -smp 2 -name MX_3 -monitor pty -boot c 
-drive file=/var/vm/vm1/qemu/images/MX_3/MX_3.img,if=ide,index=0,boot=on 
-drive file=/dev/sr0,if=ide,media=cdrom,index=3 -net 
nic,macaddr=00:0c:29:e3:bc:ee,vlan=0 -net 
tap,fd=17,script=,vlan=0,ifname=vnet1 -serial none -parallel none -usb
