injecting network configuration to windows based VM

The VM image is checked by fdisk before mounting, if the windows partition is found a batch file for changing network settings by the command netsh.exe is injected to the VM.
Before doing the above action the a windows VM must be installed in the way as suggested in the openstack's wiki webpage and a template of batch file is made(which will be processed by python-cheetah later).
After that, one must run gpedit.msc as administrator and choose a empty batch file named c:\opentack_net.bat, such that it will to be executed during system boot and set up the network configurations.
