Virt-install

Introduction

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

Installation

virt-install tool is part of the _______ package in Fedora :

# dnf install ________

The simpliest command

Use the following command to automatically launch the fedora installation process. It will also automatically create a disk image to install Fedora on.

virt-install --install fedora32
  • Note : the virt-install package that comes with Fedora 34 doesn't work yet with argument fedora34

Going further

Don't launch any installation, just create a VM

virt-install \
    --connect qemu:///system \
    --virt-type kvm \
    --arch x86_64 \
    --machine q35 \
    --boot uefi \
    --vcpus 2 \
    --cpu host-model,topology.sockets=1,topology.cores=1,topology.threads=2 \
    --memory 4096 \
    --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 \
    --install no_install=yes

Launch the installation for Fedora 34 server

  • KVM-accelerated EFI-based machine, using the Q35 chipset, with a virtio-based graphic and network card. Connection through spice. A 10G disk image is created under the default location libvirt location.
    --location /var/lib/libvirt/iso/Fedora-Server-dvd-x86_64-34-1.2.iso \
    --install no_install=no

Automated installation with local iso and kickstart

Note : requires an Internet connection

  • Remove the following
    --disk none \
    --install no_install=yes
  • Replace it with :
    --disk path=/var/lib/libvirt/images/vmd.img,format=raw,bus=virtio,cache=writeback,size=10 \
    --location=/var/lib/libvirt/iso/Fedora-Server-dvd-x86_64-34-1.2.iso \
    --extra-args="inst.ks=https://git.phyllo.me/home/kickstart/raw/branch/master/leaves/vmd.cfg"

vmd, 'v' for virtual machine, 'm' for minimal, 'd' for development only.

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 \
    --vcpus 2 \
    --memory 4096 \
    --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=10 \
    --location=/var/lib/libvirt/iso/Fedora-Server-dvd-x86_64-34-1.2.iso \
    --extra-args="inst.ks=https://git.phyllo.me/home/kickstart/raw/branch/master/leaves/vmd.cfg"
  • Alternatively, the following location can be picked [Doesn't work as of now. Would need to modify the kickstart, perhaps]

## Doesn't work (tm)

### Automated installation with remote image 

* **to-do**
$ qemu-img create -f raw /var/lib/libvirt/images/ks.img 10G

## ARM

Start serial QEMU ARM VM, which requires specifying a manual kernel.

virt-install
--name armtest
--memory 1024
--arch armv7l --machine vexpress-a9
--disk /home/user/VMs/myarmdisk.img
--boot kernel=/tmp/my-arm-kernel,initrd=/tmp/my-arm-initrd,dtb=/tmp/my-arm-dtb,kernel_args="console=ttyAMA0 rw root=/dev/mmcblk0p3"
--graphics none

### Other commands

Uses libosinfo's unattended install support, which will perform the fedora29 install automatically without any user intervention:

`virt-install --install fedora29 --unattended`

### Virt-install with cloud-init

`virt-install --install fedora34,cloud=yes --cloud-init root-password-generate=on ssh-key=/home/user/.ssh/test_rsa.pub disable=on`
