Did you try running Xvnc in the domU?

It is not exactly up-to-date X server implementation but it should be
able to run simple desktop like fluxbox fine.

I wonder what the gdm is trying to do because if it indeed hit a fatal
server error you would not be able to see the gdm login screen.
Perhaps it is trying to allow remote logins *and* start a local X
server?

Apparently the X server complains that you do not have a keyboard
which can be prevented by setting up the X server to ignore empty
input.

I suspect that either your X session is just broken and ends very
quickly (which happens often on NetBSD as the WM packages do not ship
pre-made session files) or gdm gets confused about the local server
crashing and does something stupid.
