I think there are more than one. One thing is to check what is enabled, then disable or uninstall whatever owns the unit(s): systemctl list-unit-files | egrep 'net|dhcp' Do the same with whatever "manages" /etc/resolv.conf, and create a regular file of your own design. I don't use VMs, but I did several hours ago instruct several hours ago using systemd-network to setup static IP service for a *buntu user who couldn't get netplan sorted: <https://www.linuxquestions.org/questions/ubuntu-63/netplan-apply-no-longer-setting-static-ip-address-4175738702/#post6512274> I've been using systemd-network static IPs on everything for several years, including Bullseye. -- Evolution as taught in public schools is, like religion, based on faith, not based on science.
