First, congrats on the release to the whole team. Really great to see
the progress and a fast, lean ubuntu-core image to try series 16 with a
defined set of features now \o/

I'm going to add some additional info after trying it.

Note that the images are provided in .xz format (and suffixed with
-beta3.img.xz). People need to unpack them first (for instance, with
xzcat ubuntu-core-16-amd64-beta3.img.xz >
ubuntu-core-16-amd64-beta3.img). Note that the .img image is
approximately ~4G (with a lot of empty space to install your snap, no
dynamic resize enabled on those yet).

I was wondering if snapweb was listening to a different port, but after
booting up the image, I saw that it was still listening on 4200. The
correct command is thus:

    $ kvm -m 1500 -redir tcp:10022::22 -redir tcp:4200::4200 ubuntu-core-16-amd64.img

You didn't indicate the password here. I tried USER, ubuntu, blank, but
doesn't seem to have any effect. Any hint? :)

Note: as said above, the actual port is 4200, so http://localhost:4200

This was already discussed on some bug report and known, but a note for
newcomers: the keyboard is qwerty only (I guess US layout?). So, it can
be quite an adventure to find the . and @ on other layouts ;)

Once you have done the initial email registration, this isn't an issue
anymore as you will ssh to the machine which will use your local
configuration.

Good work Michael and the team! Thanks again :)
