I have built a VirtualBox virtual machine and installed Debian 11 with
SSH server and standard system utilities only. I plan to use the VM to
run the UniFi Network Controller to manage the UniFi equipment on my
SOHO LAN:
<snip>
The VM currently has a DHCP address. I would like to set a static IPv4
address. The Debian wiki tells me to edit /etc/network/interfaces and
provides some example settings that I believe I can adapt to my use-case:

The Debian wiki also says:
"Make sure to disable all DHCP services, e.g. dhcpcd."
What is the correct method to "disable all DHCP services"?
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'
2024-07-04 20:26:35 root@unifi ~
# systemctl list-unit-files | egrep 'net|dhcp'
networking.service enabled enabled
systemd-network-generator.service disabled disabled
systemd-networkd-wait-online.service disabled disabled
systemd-networkd.service disabled enabled
systemd-networkd.socket disabled enabled
network-online.target static -
network-pre.target static -
network.target static -
Do the same with whatever "manages" /etc/resolv.conf,
How do I determine what 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:

I've been using systemd-network static IPs on everything for several years,
including Bullseye.

# man systemd-network
No manual entry for systemd-network
How do you use systemd-network to configure an interface with a static
IP address?
