## Using virt-install
|

|
||||
# Virt-install and Fedora guests
|
||||
|
||||
## Introduction
|
||||
|
||||
*virt-install* is a command-line utility to install virtual machines.
|
||||
|
||||
### Prerequesites
|
||||
|
||||
* These prerequesites are for Fedora only, as Phyllome OS ships with virt-install by default.
|
||||
|
||||
Install the *virt-install* command-line tool on Fedora :
|
||||
|
||||
```
|
||||
# dnf install virt-install
|
||||
```
|
||||
|
||||
## Manual installation
|
||||
|
||||
Use the following command to automatically launch the Fedora installation process. It will also automatically create a disk image to install Fedora on. Make sure you have at least 20 GB of free space.
|
||||
|
||||
```
|
||||
$ virt-install --install fedora32
|
||||
|
||||
Using fedora32 --location https://download.fedoraproject.org/pub/fedora/linux/releases/32/Everything/x86_64/os
|
||||
Using default --name fedora32
|
||||
Using fedora32 default --memory 2048
|
||||
Using fedora32 default --disk size=20
|
||||
|
||||
Starting install...
|
||||
Retrieving file vmlinuz... | 10 MB 00:00:00
|
||||
Retrieving file initrd.img... | 74 MB 00:00:03
|
||||
Allocating 'fedora32-2.qcow2' | 20 GB 00:00:00
|
||||
Running graphical console command: virt-viewer --connect qemu:///session --wait fedora32
|
||||
```
|
||||
|
||||
It should automatically launch the guest console. Eventually, you should see the Anaconda installer first page.
|
||||
|
||||
Other options include : `android-x86-9.0`, `centos8`, `clearlinux`, `debian9`, `macosx10.7`, `nixos-20.03`, `ubuntu20.04`, `win10`

## Automated installation
|
||||
|
||||
### Local iso and kickstart
|
||||
|
||||
> Requires an Internet connection
|
||||
{.is-info}
|
||||
|
||||
* Fetch a Fedora iso file using wget and put it in the current working directory
|
||||
|
||||
```
|
||||
$ wget https://download.fedoraproject.org/pub/fedora/linux/releases/34/Server/x86_64/iso/Fedora-Server-dvd-x86_64-34-1.2.iso
|
||||
```
|
||||
|
||||
* Fetch a kickstart script using wget and put it in the current working directory
|
||||
|
||||
```
|
||||
$ wget https://git.phyllo.me/home/kickstart/raw/branch/main/leaves/imd.cfg
|
||||
```
|
||||
|
||||
> If using a custom kickstart script, make sure it includes the cdrom option.
|
||||
{.is-warning}
|
||||
|
||||
|
||||
* Deploy a UEFI-based machine with Fedora Server using the relative path of the local kickstart file
|
||||
|
||||
```
|
||||
$ virt-install \
|
||||
--connect qemu:///system \
|
||||
--virt-type kvm \
|
||||
--arch x86_64 \
|
||||
--machine q35 \
|
||||
--name imd \
|
||||
--boot uefi \
|
||||
--cpu host-model,topology.sockets=1,topology.cores=2,topology.threads=2 \
|
||||
--vcpus 4 \
|
||||
--memory 8192 \
|
||||
--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 path=/var/lib/libvirt/images/imd.img,format=raw,bus=virtio,cache=writeback,size=5 \
|
||||
--location=/var/lib/libvirt/iso/Fedora-Server-dvd-x86_64-34-1.2.iso \
|
||||
--initrd-inject imd.cfg --extra-args "inst.ks=file:/imd.cfg"
|
||||
```
|
||||
### Remote installation with local kickstart
|
||||
|
||||
> Requires an Internet connection
|
||||
{.is-info}
|
||||
|
||||
* Fetch a kickstart script using wget and put it in the current working directory
|
||||
|
||||
```
|
||||
$ wget https://git.phyllo.me/home/kickstart/raw/branch/main/leaves/vmd.cfg
|
||||
```
|
||||
|
||||
> If using a custom kickstart script, make sure it includes repo information
|
||||
{.is-warning}
|
||||
|
||||
```
|
||||
$ virt-install \
|
||||
--connect qemu:///system \
|
||||
--virt-type kvm \
|
||||
--arch x86_64 \
|
||||
--machine q35 \
|
||||
--name vmd \
|
||||
--boot uefi \
|
||||
--cpu host-model,topology.sockets=1,topology.cores=2,topology.threads=2 \
|
||||
--vcpus 4 \
|
||||
--memory 8192 \
|
||||
--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 path=/var/lib/libvirt/images/vmd.img,format=raw,bus=virtio,cache=writeback,size=5 \
|
||||
--location=https://download.fedoraproject.org/pub/fedora/linux/releases/34/Everything/x86_64/os/ \
|
||||
--initrd-inject bmd.cfg --extra-args "inst.ks=file:/bmd.cfg"
|
||||
```
|
||||
|
||||
### 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:///system \
|
||||
--virt-type kvm \
|
||||
--arch x86_64 \
|
||||
--machine q35 \
|
||||
--name flat-dmd \
|
||||
--boot uefi \
|
||||
--cpu host-model,topology.sockets=1,topology.cores=2,topology.threads=2 \
|
||||
--vcpus 4 \
|
||||
--memory 8192 \
|
||||
--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 path=/var/lib/libvirt/images/flat-dmd.img,format=raw,bus=virtio,cache=writeback,size=5 \
|
||||
--location=https://download.fedoraproject.org/pub/fedora/linux/releases/34/Everything/x86_64/os/ \
|
||||
--extra-args="inst.ks=https://git.phyllo.me/home/kickstart/raw/branch/main/flat/flat-dmd.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`
