Virt-install

Introduction

virt-install is a command-line utility to install virtual machines.

Installation

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

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

The virt-install package that comes with Fedora 34 doesn't work yet with argument fedora34 {.is-warning}

Local iso and kickstart

• Fetch a Fedora iso file

$ wget https://download.fedoraproject.org/pub/fedora/linux/releases/34/Server/x86_64/iso/Fedora-Server-dvd-x86_64-34-1.2.iso -P /var/lib/libvirt/iso 

• Deploy a Fedora Server using Phyllome OS curated kickstart

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=1,topology.threads=2 \

Built-in unattended mode

virt-install can rely on libosinfo's unattended install support to deploy fedora34 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
