## Description:
script which permit to launch easily some virtual machines via qemu

## Dependencies:

- <u>qemu</u> full installation

## Functionnality:

- create a config file to stores options for a vm [~]
- start a vm while reading for the conf file [ok]
- create a vm with the ability to choose an iso disk to launch the vm [ok]
- del all sata related to a vm [~ok] (misses deleted conf file)
- create a backup or being able to recall the bacup [ok] (can be improved)
- start directly the backup file [ok]
- can create only the conf file instead of starting/creating vm [ok]
- list all vm already created [ok]
- print help of version number [ok]
- support option nproc to launch the vm with a different number of proc than precised in the config file [ok]
- same for option memory [ok]

## 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.
