# Script deploys VyOS network OS to QEMU instance running on localhost 3355 with attached VyOS ISO 
#
# Prior to starting this script you must download VyOS ISO and create QEMU blank disk:
# /usr/local/bin/qemu-img create -f vmdk vyos-amd64.vmdk 2G
# 
# Then you can run Qemu disk using cdrom parameter with attached ISO e.g.
# /usr/local/bin/qemu-system-x86_64 -boot c -cdrom vyos-1.2.0-epa2-amd64.iso -hda vyos-amd64.vmdk -m 4G -enable-kvm -serial telnet:127.0.0.1:3355,server,nowait
