# vms
This script is a simple tool that uses QEMU to create, run, and manage virtual
machines.
It is a tool to simplify the management of multiple headless VMs without a
graphical interface, using tools like `ssh`, `sshfs`, and `rsync`. The script
uses minimal QEMU arguments to avoid excessive CPU usage. If you want to use
`Spice` or other tools with QEMU, feel free to open a pull request to integrate
that into the configuration.
## Prerequisites
Ensure you have the following dependencies installed:
- `qemu-img`
- `qemu-system-x86_64`
## Installation
Run:
```sh
$ make PREFIX=/home/USER/.local install
```
## Usage
The first time you run `vms` command, it will create a `vms` directory under
your home directory to store the images, configs, and ISOs for the VMs.
First, download the ISO image, for example, [arch linux](https://archlinux.org/download/).
The following command will create a new image in `vms` direcotry using `qemu-img`
with the provided size, and create a config file.
```sh
$ vms create arch 50G
```
Read/Modify the config file in: `/home/USER/vms/arch.conf`
Then you can boot from the ISO:
```sh
$ vms boot arch /home/USER/download/arch.iso
```
After installing, you can run this command whenever you want to run the VM:
```sh
$ vms run arch
```
You can list all VMs by using this command:
```sh
$ vms list
```
## Configuration
By default, the script uses the following configurations for the virtual
machines:
```sh
### Default vm configuration
# ram=12G
# cpu=host
# graphic=yes
# audio=no
#
# Forward host port 10022 to guest port 22 and host port 8080 to guest port 80
# ports=10022:22 8080:80
#
# display=sdl,grab-mod=rctrl
# vgadevices=VGA,vgamem_mb=64
# audiodevices=intel-hda hda-duplex
# devices=
```
These default settings can be customized by modifying config files.
