# libvirt hooks nushell
A conventional and user-friendly Libvirt hook script written in Nushell, offering enhanced flexibility for those who prefer simplicity, laziness and convenience, like myself.
## Distinguishable Features
- Disable Hooking for Specific VMs: You can easily disable the entire hook system for any VM by simply appending specific suffixes to the VM name. If a VM name ends with:
- "-woh", "-without-hooks", "-nh", or "-no-hooks", hooks will be disabled for that VM.
- Default Hooks for Simplicity: For users who manage multiple VMs with identical configurations, the default hooks can be enabled automatically. No need to write redundant code!
- Disable Default Hooks: Disable the default hook system for any VM by appending:
- "-nd", "-no-default", "-wod", or "-without-default" to the VM name.
## Generic Folder Structure
```
/etc/libvirt/hooks/
- qemu # (main.nu file in this case)
- qemu.d # (where your custom hooks go)
```
Below is an example folder structure, if you want, you can make them one single script in `/etc/libvirt/hooks/qemu.d/win11vm`, but consider managing command line arguments, you can
read more about [libvirt hooks here](https://passthroughpo.st/simple-per-vm-libvirt-hooks-with-the-vfio-tools-hook-helper/).
```
/etc/libvirt/hooks/qemu.d/
- win11vm
- prepare
- begin
- 00-reserve-hugepages
- 01-isolate-cpus
- 02-etc.
- stopped
- end
- 99-release-hugepages
- 98-revert-cpus
- 97-etc.
```
## Installation
```
git clone https://github.com/atahabaki/libvirt-hooks-nushell/
cd libvirt-hooks-nushell
source toolkit.nu
install
```
That's it. The only thing left is configuration, writing the hooks or default-hooks for your own VMs, take care.
After install make sure to restart `libvirtd` sytemd service, as below:
```
systemctl restart libvirtd
```
