From Colin Percival on port-xen@:

I noticed a few days ago that the EC2 images you provide
  https://wiki.netbsd.org/amazon_ec2/amis/
and the build instructions
  https://wiki.netbsd.org/amazon_ec2/build_your_own_ami/
are for PV mode.  As a result, those images won't run on any of the
modern EC2 instance types -- EC2 has moved to HVM (or more precisely,
HVM with paravirtual and/or SR-IOV devices).

If any of you want are interested in modernizing your EC2 offering, I'll
be happy to help; as the maintainer of the FreeBSD/EC2 platform, I've
probably tripped over many of the same issues you'll encounter.  And if
we can get a better NetBSD offering in EC2, it might help to get them to
stop classifying BSDs as "other Linux"...
