You mean a "self registering dns name"?

I'm currently using a solution based on LDAP-backed DNS and DHCP (including
PXE options). The problem I have is how to "join" the information based on
IDs in Proxmox VE with the hostname. I can join based on MAC if all
machines are registered, but not otherwise.

There was a discussion about getting IP addresses via qemu-agent and
display it in the Proxmox VE GUI, but that only helps for VMs running with
the agent. It would be simpler to add - SQL-technically speaking - a
hostname column to the KVM VMs. I need something to join and the VM name
can be ambiguous.

In the end I want to see on the overview page of a VM what the hostname
and/or IP is for logging in. Currently I did it in the comment.
