Installing Qemu on Artix(runit)

doas pacman -S qemu virt-manager virt-viewer dnsmasq vde2 bridge-utils openbsd-netcat libvirt libvirt-runit

doas ln -s /etc/runit/sv/libvirtd /run/runit/service
doas ln -s /etc/runit/sv/virtlogd /run/runit/service
doas ln -s /etc/runit/sv/virtlockd /run/runit/service

<OPTIONAL: CUSTOM LOGGING SECTION>
cd /etc/runit/sv/libvirtd/log

doas nvim run

Edit the log to read:

#!/bin/bash
exec 2>&1; set -e

[ -d /var/log/libvirtd ] || install -dm /var/log/libvirtd

exec svlogd -tt /var/log/libvirtd

Write/Quit out of file.

cd /var/log/

doas mkdir libvirtd

<END OF OPTIONAL LOGGING SECTION>

doas nvim /etc/libvirt/libvirtd.conf Uncomment The Following Lines:

unix_sock_group = "libvirt"
unix_sock_ro_perms = "0777"
unix_sock_rw_perms = "0770"

Write/Quit out of file.

Add current user to libvirt group:

doas usermod -aG libvirt <username>

Reboot.

cd /usr/share/libvirt/networks

doas touch default.xml

Copy the following into default.xml(also available in notes/virsh):

<network>
  <name>default</name>
  <uuid>9a05da11-e96b-47f3-8253-a3a482e445f5</uuid>
  <forward mode='nat'/>
  <bridge name='virbr0' stp='on' delay='0'/>
  <mac address='52:54:00:0a:cd:21'/>
  <ip address='192.168.122.1' netmask='255.255.255.0'>
    <dhcp>
      <range start='192.168.122.2' end='192.168.122.254'/>
    </dhcp>
  </ip>
</network>

If you are already using dnsmasq with mullvad, you may want to start off without internet:

<network>
  <name>default</name>
  <forward mode='nat'/>
  <dns enable='no' />
  <ip address='192.168.250.1' netmask='255.255.255.0'>
    <dhcp>
        <range start='192.168.250.2' end='192.168.250.254'/>
    </dhcp>
  </ip>
</network>

doas virsh net-define --file default.xml

doas virsh net-start default

doas virsh net-autostart --network default

doas sv restart libvirtd

doas sv restart libvirtd/log

doas sv restart virtlockd virtlogd

Keep in mind that if you start without internet, you'll have to drop the host firewall to get it to work. There are ways of getting it to work with ufw and iptables, but I have yet to bother diving further into this.

The following forum post on linuxquestions.org might help if you run into further trouble:
