Unattended deployment of RPM-based guests

• virt-install is a command-line utility that can be used to create virtual machines. It comes preinstalled with Phyllome OS.

Deployment using a hosted kickstart file

• The following command will deploy a virtual machine with a stripped-down GNOME desktop environment. Adjust the settings according to your needs.

Please verify the content of the kickstart script used to automate the installation. You may replace the kickstart script by a kickstart script of your choice. {.is-info}

virt-install \
    --connect qemu:///system \
    --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=default,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/virtual-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/dishes/virtual-desktop.cfg"

Deployment using a local kickstart file

• Use the following wget command to fetch a standalone kickstart file made to deploy a stripped-down desktop system with GNOME Shell, and put it in the working directory

wget https://raw.githubusercontent.com/PhyllomeOS/phyllomeos/main/dishes/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 using a custom kickstart script, make sure it includes the repo information {.is-warning}

• Deploy a stripped down desktop based on GNOME Shell using the local kickstart file previously downloaded

virt-install \
    --connect qemu:///system \
    --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=default,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/virtual-desktop.img,format=raw,bus=virtio,cache=writeback,size=10 \
    --location=https://download.fedoraproject.org/pub/fedora/linux/releases/35/Everything/x86_64/os/ \
    --initrd-inject virtual-desktop.cfg --extra-args "inst.ks=file:/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 \
    --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=default,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 none \
    --cdrom=/var/lib/libvirt/iso/netboot.xyz.iso \
    --install no_install=yes

Automated installation using an ISO file and a local kickstart file

Warning

: doesn't work as intended. The kickstart file won't have to be modified to include the cdrom option and the ISO would have to include the necessary packages. {.is-danger}

• 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 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/dishes/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

virt-install \
    --connect qemu:///system \
    --os-variant detect=off \
    --virt-type kvm \
    --arch x86_64 \
    --machine q35 \
    --name virtual-desktop-cdrom \
    --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 \
