I was able to reproduce the bug on Focal, and since we seem to carry the same version on Jammy/Mantic (and likely Noble), it's probable that the bug also happens in those releases.

For future reference:

# apt install -y libvirt-daemon-system bind9 dnsmasq

Reboot, and try bringing up the "default" network on libvirt:

# virsh net-start default
error: Failed to start network default
error: internal error: Child process (VIR_BRIDGE_NAME=virbr0 /usr/sbin/dnsmasq --conf-file=/var/lib/libvirt/dnsmasq/default.conf --leasefile-ro --dhcp-script=/usr/lib/libvirt/libvirt_leaseshelper) unexpected exit status 2:
