I have managed to get NetBSD-HEAD running as a domu.
I am currently attempting to add pf support to the kernel.

When I try to start the vm with that kernel I saw
ERROR: Malformed ELF image.
ERROR: Error constructing guest OS
in the xend-debug.log

I reverted back to the kernel that works and attempted again
to build the stock XEN3_U kernel via
./build.sh tools kernel=XEN3_U
and received the same results.

This is the 5/27 snapshot of HEAD.

I'm going to assume that I'm screwing something up, but I'm unsure as
to what.
