What do you mean with "standard domU format"? I think the different
implementations on different distributions all have their pros and
cons - I tested them on Fedora, SuSE, Ubuntu and Debian. Too long to
name all differences and pros and cons, but they all have theirs.

The problem with NetBSD is that the current available NetBSD Kernels
have a different PAE setting than the Fedora xen packages.
One would need to get a PAE-enabled NETBSD DomU Kernel - don't know if
this is just a simple compile switch and recompile, or if it's harder
to get. I've not found the time to ask the netbsd developers for a
solution.

Apart from that, there is not much of "following Fedoras path"
required for the others - basically virt-manager would only be
required to use the (when available as PAE) NetBSD Install kernel
instead of the Linux Kernel, and after installation switch to the
NetBSD runtime kernel.
That should be doable.
