Hi Michael,

First, thanks for your detailed instructions. I just followed your steps to
install the QEMU to test the Ubuntu Core. However, I have to problems in
logging into the Ubuntu Core. The captured screen is like
http://imgur.com/a/Qyfc9. May I know what the correct password for logging
into the Ubuntu core. Is it the one for Ubuntu One? or the one for the ssh?

Thanks & best regards,

> Hi,
> The Snappy team is happy to announce the release of Ubuntu Core 16.
> Ubuntu Core is an operating system entirely based on snaps, including
> its foundation. Applications, kernel, core operating system, and
> gadget components are all managed as snaps and are installed and
> refreshed by snapd, the daemon and tooling responsible for making it
> all dance.
> The images are available currently for PC (amd64, i386) and
> for Pi2/Pi3 and Dragonboard. These images can be downloaded from:
>     http://releases.ubuntu.com/ubuntu-core/16/
> Once unpacked, the images are bootable, the PC image can be booted
> directly in qemu-kvm, virtualbox or on real hardware. When running the
> images in qemu-kvm it is helpful to use the "-redir" feature of
> qemu-kvm. e.g.:
>     $ kvm -smp 2 -m 1500 -redir tcp:10022::22 ubuntu-core-16-amd64.img
> The message from console-conf is a bit misleading in this setup. It
> will say "ssh USER at". However due to the way that the
> qemu-kvm user networking behaves, you will actually have to run the
> following to ssh into the images:
>     $ ssh -p 10022 USER at localhost
> or if you have the following snippet in ~/.ssh/config
> Host kvm.snappy
>      Hostname localhost
>      Port 10022
>      User USER
>      UserKnownHostsFile /dev/null
>      StrictHostKeyChecking no
> then you can just
>     $ ssh kvm.snappy
> into it.
> The Pi2/Pi3/Dragonboard image can be written to a sdcard via dd. An
> alternative way to write the image is to use "go-dd", e.g. on Ubuntu
> 16.04:
>      $ sudo snap install --devmode --beta godd
>      $ sudo /snap/bin/godd ubuntu-core-16-pi2.img.xz
>      [this will print a message showing what devices are removable]
>      $ xzcat ubuntu-core-16-pi2-rc2.img.xz | sudo /snap/bin/godd -
> /dev/sdXX
> After booting the image you can enter your Ubuntu One email and it
> will automatically create a matching user with the right ssh keys. If
> you do not have an Ubuntu SSO account yet please create one at:
>     https://login.ubuntu.com/
> (don't forget to add your public ssh keys to that account).
> Known issues:
> - pi3 wlan can not be initially configured, wired network needs to be
>   used for the initial setup (you can re-run "sudo console-conf" at
>   any later point to re-configure the device for wlan only
>   operation).
> Bug references for the pi3 known issues:
> - http://pad.lv/1637153
>   plugging in network cable during configuration can cause a traceback
>   on pi3
> - http://pav.lv/1624322
>   no wlan0 device at all on first boot on pi3
> - http://pad.lv/1632387
>   wifi setup times out on pi3 devices on first boot
> These images follow the "stable" channel. If you find any issues,
> please let us know via:
>     https://bugs.launchpad.net/snappy/
> Ubuntu Core 16 follows a rolling release model, security updates and
> bug fixes will come to you via regular over the air updates for the
> lifetime of the release.
> Enjoy this release!
> Cheers,
