Next changes to come

• put the path of the creation disk on the config file
• add vnc support
• add an option -ng, --nographic with it's parametters assiciated.
• majors changes in setup_bridges.sh, it will be from this point called

setup_bridges 'bridge_name' add|rm [--ip=<ip> | --imaster=<interface_master>]

Usage:

to get some help;

vm-start --help

to list all vm already configured

vm-start --list

to create a new vm

vm-start <nom_de_la_vm> create --create_disk=<location_of_iso_file>

you can of course add options like --uefi to tun in uefi mode, or --nproc=<nb_proc> to select a number of processors.

If you go to the conf folder created the first time you launch the script, you will find all configured variables for each of your vm.

to connect two vm on different networks at a gateway nat.

first, run the script set-tap.sh to create two bridges.

setup_bridge.sh --addbridge=br0
setup_bridge.sh --addbridge=br1

after that change the mac address of all vm in conf folder.

vm-1 from 00:00:00:00:00:00 to 00:00:00:00:00:01
vm-2 from 00:00:00:00:00:00 to 00:00:00:00:00:02

and start the gateway and the vms after.

vm-start.sh gateway start --net=br:br0 --net=br:br1 --net=nat:id01
vm-start.sh vm-1 start --net=br:br0
vm-start.sh vm-2 start --net=br:br1

And that's it, your three vm are now connected. You just have now to do some configurations on thoses vms.
