Uses the official document,
I installed maas uses snap ,and found a dhcp problem, Created a dhcp snippets and enabled it,as the screenshot below:

maas-dhcp
maas-dhcp1372×464 41.7 KB

you can see the warrning of the dhcp service: " DHCP is not enabled on any VLAN. This will prevent machines from being able to PXE boot, unless an external DHCP server is being used." is stll exist.

To be notesd, I have skipped all the “first time use configure”.

And here is the search result of the dhcp-service model below :

root@autoinstall:~# ps -ef | grep dhcp

@lxl2024 –

machines provisioned by MAAS must have a DHCP server. DHCP snippets can be enabled, but without DHCP, there’s no place for a MAAS machine to get an IP address, so the snippet isn’t getting applied by anything.

you also need the address of a TFTP/HTTP boot server to deliver an NBP that will let the machine PXE boot. try following the instructions you skipped, it should work much better.
