# vm-start

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

## Dependencies:

- <u>qemu</u> full installation


## Optionnal Dependencies:
- <u>ssh</u> to have possibility to connect via ssh with the remote_connection.sh script.
- <u>rsp</u> to have possibility to connect via rsp with the remote_connection.sh script.

## Functionnality:

- use of config files [not fully ok]
- start,create vm reading the config file [ok]
- delete all data related to a vm [ok]
- create a backup or being able to recall the bacup [ok - have to be improved]
- start directly the backup file [ok]
- list all vm already configured [ok]
- print help of version number [ok]
- support options to overrides the config file [ok]
- can support launching vm in uefi mode [ok] (doesn't support automatic add of uefi in conf file.)
- take option create_disk to know what disk to use when creating a vm. [ok]
- compatible to an extensive network configuration [~ok] (don't work with conf file, and no possibility to bridge over an existing interface.)

### 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 --add-br-id=br0
setup_bridge.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.
