libvirtd-desktop

libvirtd, qemu, swtpm, virt-install and guestfs-tools for desktop usage.

See the Virtual Machine Manager Flatpak.

How to use

Install the sysext

Create the qemu user:

$ sudo systemd-sysusers /usr/lib/sysusers.d/libvirt-qemu.conf

Copy the some default config:
```
$ sudo cp -a /usr/etc/mdevctl.d /etc/
```
Optional: Copy the default libvirtd config (note that it won’t be updated automatically):
```
$ sudo cp -a /usr/etc/libvirt /etc/
```

Optional: Setup auth via polkit (example):

$ sudo cat /etc/polkit-1/rules.d/50-libvirt.rules
polkit.addRule(function(action, subject) {
    if (action.id == "org.libvirt.unix.manage" &&
        subject.isInGroup("wheel")) {
            return polkit.Result.YES;
    }
});

Restart libvirtd (via virtqemud, virtnetworkd & virtstoraged):

$ sudo systemctl restart virtqemud.socket virtnetworkd.socket virtstoraged.socket

Usage instructions

First time setup

Run those commands if you have not yet installed any sysext on your system:

sudo install -d -m 0755 -o 0 -g 0 /var/lib/extensions /var/lib/extensions.d
sudo restorecon -RFv /var/lib/extensions /var/lib/extensions.d

Installation

Define a helper function:

install_sysext() {
  SYSEXT="${1}"
  URL="https://extensions.fcos.fr/extensions"
  sudo install -d -m 0755 -o 0 -g 0 /etc/sysupdate.${SYSEXT}.d
  sudo restorecon -RFv /etc/sysupdate.${SYSEXT}.d
  curl --silent --fail --location "${URL}/${SYSEXT}.conf" \
    | sudo tee "/etc/sysupdate.${SYSEXT}.d/${SYSEXT}.conf"
  sudo /usr/lib/systemd/systemd-sysupdate update --component "${SYSEXT}"
}

Install the sysext:

install_sysext libvirtd-desktop

Merging

Note that this will merge all installed sysexts unconditionally:

sudo systemctl restart systemd-sysext.service
systemd-sysext status

Updates

Update this sysext using:

sudo /usr/lib/systemd/systemd-sysupdate update --component libvirtd-desktop

If you want to use the new version immediately, make sure to refresh the merged sysexts:

sudo systemctl restart systemd-sysext.service
systemd-sysext status

To update all sysexts on a system:

for c in $(/usr/lib/systemd/systemd-sysupdate components --json=short | jq --raw-output '.components[]'); do
    sudo /usr/lib/systemd/systemd-sysupdate update --component "${c}"
done
