Can you please try applying this temporary patch and running `./check

With this temporary patch the VM doesn't launch at all:

Well, today I learned that:
(1) vm-build-XXX targets use your host system's QEMU to run that VM
(2) my QMP library cannot talk to QEMU 2.11.
That doesn't explain the intermittent netbsd failure yet, though.
(I guess this wasn't a failure point for you due to the aggressive
caching of the VM images? Unlucky.)
Here's another hotfix, this one I cannot easily test quickly (I don't
have 2.11 handy and it no longer builds for me),
but I think it'll fix the VM installation problem against older QEMU versions:
