[Fwd: Ubuntu Core 16 beta images available]

Hi All,

I tried the instructions at https://developer.ubuntu.com/en/snappy/start/
in order to get the new Beta images at
http://cdimage.ubuntu.com/ubuntu-snappy/16.04/current/
to work on locally on KVM on Linux.

Two issues:

1. The command to start kvm should better be like

kvm -m 512M -redir :8090::80 -redir :8022::22 -drive
format=raw,file=ubuntu-core-16-amd64.img

(instead of  kvm -m 512 -redir :8090::80 -redir :8022::22
ubuntu-15.04-snappy-amd64-generic.img
which causes the warning:

WARNING: Image format was not specified for 'ubuntu-core-16-amd64.img'
and probing guessed raw.
         Automatically detecting the format is dangerous for raw
images, write operations on block 0 will be restricted.
         Specify the 'raw' format explicitly to remove the restrictions.)

In addition, I think it is better to specify M in "512M".

2. Once you configure Ubuntu Core and supply your launchpad email address
(required so that it can retrieve your SSH public key and install into
the running image),
it suggests to
            ssh -p 8022 myusername at 10.0.2.15
The instructions at the Snappy Start suggest to
           ssh -p 8022 ubuntu at localhost
(mentions that "ubuntu/ubuntu" is a hard-coded account in earlier
Ubuntu Core images).

What works with Ubuntu Core 16.04 Beta is
           ssh -p 8022 myusername at localhost
(where "myusername" is the Launchpad username. You got it right it
https://launchpad.net/~myusername is your personal Launchpad page).

All accounts on the Ubuntu Core 16.04 Beta image are locked, so it is
not possible to log in through the qemu log in screen straight away.
