# Seia-Soto/libvirtd-scripts
A small set of simple scripts to manage virtual environment on *Alpine Linux* for light users.
- Only uses about 100 to 150MB of memory on host machine
- Almost zero configuration
## Table of Contents

----
# Requirements
To use attached script files, you need to have:
- Alpine Linux 3.12 or higher version

rm -r ~/Seia-Soto-libvirtd-scripts-*
```
## `virt.install.sh`
This script makes your system almost ready to deploy virtual machines.
While making system to run virtual machine, this script will create following folders:
- `~/scripts`, directory for this scritps set.
- `~/virtuals`
- `~/virtuals/images`, directory for CD image.
- `~/virtuals/machines`, directory for VM disks.
```sh
# Uncomment community repository before start;
cat > /etc/apk/repositories << EOF; $(echo)
http://dl-cdn.alpinelinux.org/alpine/v$(cat /etc/alpine-release | cut -d'.' -f1,2)/main
http://dl-cdn.alpinelinux.org/alpine/v$(cat /etc/alpine-release | cut -d'.' -f1,2)/community
EOF
sh ~/scripts/virt.install.sh
```
For post-installation message, refer following file:
[virt.install.postinstall.md](/scripts/virt.install.postinstall.md)
## `virt.create.sh`
This script creates new Alpine Linux virtual machine on your system.
This will create an Alpine Linux virtual machine with the image downloaded when setting up new host with `virt.install.sh`.
The version is same with host machine.
```sh
sh ~/scripts/virt.create.sh [NAME] [CPU_CORES] [RAM_SIZE] [DISK_SIZE]
```
- `NAME`: (required) The name of the virtual machine.
- `CPU_CORES`: (required) The number of cores to virtualize.
- `RAM_SIZE`: (required) The max size of RAM to allocate in MB (dynamically allocated, max).
- `DISK_SIZE`: (required) The max size of qcow2 disk to allocate in GB (dynamically allocated, max).
### Notes
- This scripts will create virtual machine which attach `br0` as default network interface.
## `virt.delete.sh`
This script deletes virtual machine and its dependencies like boot disk things.
```sh
sh ~/scripts/virt.delete.sh [NAME]
```
- `NAME`: (required) The name of the virtual machine.
## `virt.add_volume.sh`
This script attaches external qcow2 disk to specific machine.
```sh
sh ~/scripts/virt.add_volume.sh [NAME] [SIZE] [PATH]
```
- `NAME`: (required) The name of the virtual machine.
- `SIZE`: (required) The number of cores to virtualize.
- `PATH`: (required) The path to attach volume, such as `vdb`, `vdc`, and `vdd`.
## `virt.get_osvars.sh`
This script runs a command `osinfo-query os`.
