# Deploy RPM-based Linux distributions automatically
|
|
|
|
`virt-install` is a command-line utility that can be used to create virtual machines. It comes preinstalled with Phyllome OS.
|
|
|
|
* For Fedora, you can install it using the following command as *root*:
|
|
|
|
```
|
|
dnf install virt-install
|
|
```
|
|
|
|
## Automated installation using an ISO file and a local kickstart file
|
|
|
|
* Use the following `wget` command to fetch the official Fedora Server ISO file and to put it in the current working directory
|
|
|
|
```
|
|
wget https://download.fedoraproject.org/pub/fedora/linux/releases/35/Server/x86_64/iso/Fedora-Server-dvd-x86_64-35-1.2.iso
|
|
```
|
|
> Please [verify your download](https://getfedora.org/en/security/) if you intent to use this virtual machine in production
|
|
{.is-info}
|
|
|
|
Move the file to `/var/lib/libvirt/iso`:
|
|
```
|
|
mv Fedora-Server-dvd-x86_64-35-1.2.iso /var/lib/libvirt/iso
|
|
```
|
|
* Use the following `wget` command to fetch a standalone kickstart file made to deploy a stripped down desktop based on GNOME Shell, and put it in the working directory
|
|
|
|
```
|
|
wget https://raw.githubusercontent.com/PhyllomeOS/phyllomeos/main/leaves/virtual-desktop.cfg
|
|
```
|
|
|
|
> Please verify the content of the script if you intent to use this virtual machine in production, for instance by using the following command `cat virtual-desktop.cfg`
|
|
{.is-info}
|
|
|
|
> If you use a custom kickstart script, make sure it does include the `cdrom` option.
|
|
{.is-warning}
|
|
|
|
* Deploy a UEFI-based machine with Fedora Server using the relative path of the local kickstart file
|
|
|
|
> Warning: doesn't work as intended.
|
|

|
|
```
|
|
|
|
### Remote installation with remote kickstart
|
|
|
|
* Alternatively, same as above but without fetching the kickstart file. The last line has to be swapped with :
|
|
|
|
```
|
|
virt-install \
|
|
--connect qemu:///session \
|
|
--os-variant detect=off \
|
|
--virt-type kvm \
|
|
--arch x86_64 \
|
|
--machine q35 \
|
|
--name virtual-desktop \
|
|
--boot uefi \
|
|
--cpu host-model,topology.sockets=1,topology.cores=2,topology.threads=1 \
|
|
--vcpus 2 \
|
|
--memory 4096 \
|
|
--video virtio \
|
|
--graphics spice,listen=none \
|
|
--channel spicevmc \
|
|
--channel unix,target.type=virtio,target.name=org.qemu.guest_agent.0 \
|
|
--autoconsole none \
|
|
--console pty,target.type=virtio \
|
|
--sound none \
|
|
--network type=user,model=virtio \
|
|
--controller type=virtio-serial \
|
|
--controller type=usb,model=none \
|
|
--controller type=scsi,model=virtio-scsi \
|
|
--input type=keyboard,bus=virtio \
|
|
--input type=tablet,bus=virtio \
|
|
--rng /dev/urandom,model=virtio \
|
|
--disk path=/var/lib/libvirt/images/phyllome-desktop.img,format=raw,bus=virtio,cache=writeback,size=10 \
|
|
--location=https://download.fedoraproject.org/pub/fedora/linux/releases/35/Everything/x86_64/os/ \
|
|
--extra-args="inst.ks=https://raw.githubusercontent.com/PhyllomeOS/phyllomeos/main/leaves/virtual-desktop.cfg"
|
|
```
|
|
|
|
### Local deployment without installation
|
|
|
|
The idea here is to define a virtual machine and use the netboot.xyz.iso as a way to boot into an installer.
|
|
|
|
```
|
|
virt-install \
|
|
--connect qemu:///system \
|
|
--virt-type kvm \
|
|
--arch x86_64 \
|
|
--machine q35 \
|
|
--name live-with-netboot-xyz \
|
|
--boot uefi \
|
|
--cpu host-model,topology.sockets=1,topology.cores=1,topology.threads=1 \
|
|
--vcpus 1 \
|
|
--memory 2048 \
|
|
--video virtio \
|
|
--channel spicevmc \
|
|
--autoconsole none \
|
|
--sound none \
|
|
--controller type=virtio-serial \
|
|
--controller type=usb,model=none \
|
|
--controller type=scsi,model=virtio-scsi \
|
|
--network network=default,model=virtio \
|
|
--input type=keyboard,bus=virtio \
|
|
--input type=tablet,bus=virtio \
|
|
--rng /dev/urandom,model=virtio \
|
|
--disk none \
|
|
--cdrom=/var/lib/libvirt/iso/netboot.xyz.iso \
|
|
--install no_install=yes
|
|
```
|
|
|
|
### Built-in unattended mode
|
|
|
|
virt-install can rely on libosinfo's unattended install support to deploy fedora34 without any user intervention:
|
|
|
|
`virt-install --install fedora32 --unattended`
|
|
|
|
### Cloud-init
|
|
|
|
Cloud-init may be used alongside virt-install:
|
|
|
|
`virt-install --install fedora34,cloud=yes --cloud-init root-password-generate=on ssh-key=/home/user/.ssh/test_rsa.pub disable=on` |
