--- title: Automatic deployment of a Fedora guest automatically description: Deploy a Fedora automatically with virt-install published: true date: 2021-08-12T10:06:58.917Z tags: editor: markdown dateCreated: 2021-08-12T10:06:58.917Z --- # 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] ``` virt-install \ --connect qemu:///system \ --virt-type kvm \ --arch x86_64 \ --machine q35 \ --name vmd-internet \ --boot uefi \ --cpu
