Usage:

to get some help;

vm-start --help

to list all vm already configured

vm-start --list

to create a new vm

vm-strart <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.

set-tap.sh --add-br-id=br0
set-tap.sh --add-br-id=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.
