It works on earlier versions and this is news to me, so yes this is a
bug, unless Xen upstream withdrew support and it's a doc bug.

It would be helpful to figure out the envelope of what doesn't work.
i386-{6,7,current} might work, Xen 4.2 probably does, and a -6 or -7
dom0 might.  I know a xen 4.2 dom0 netbsd-5 system is fine.

It would help too if your report were a minimal example, and could be
made to work by changing to amd64.  gson@ has produced test cases that
install netbsd in qemu, install the xen pkgs, and then install a domU
and run the tests in the domU.  See
for an example reproduction script.
