One problem I see is that the client relies on a VM that might not be up
when Samba on the client boots. If there are other services running on
the client, that use winbind for authentication or for building a list
of users, they might fail as well. Additionally the client uses the DCs
DNS, so services might fail during start up if the DNS is not up.

If you have only one physical machine, I would put both into a VM or at
least the client and run the DC native on the machine.
