Where should these reports be filed at?

I could not find the source location of the page
https://developer.ubuntu.com/en/snappy/start/

The closest was this one (for the new 16.04),
http://bazaar.launchpad.net/~developer-ubuntu-com-dev/developer-ubuntu-com/stable/view/head:/md_importer/tests/data/website-test/out/get-started/as-dev/16.04/step2-setup-kvm-ubuntu.md

There is the old and active repository at
https://bugs.launchpad.net/developer-ubuntu-com

There is also the new but not yet active repository on github,
https://github.com/ubuntudesign/developer.ubuntu.com/issues

I believe there will be some new users that will not notice this.
An option is to say so on the final page of the installation.

it strikes me though that you can not really know the redirected ssh
port from inside the VM ...

nah, you can have that cheaper apparently:

ogra@localhost:~$ grep "model name" /proc/cpuinfo
model name  : QEMU Virtual CPU version 2.4.0

yeah, that'd need dmidecode which isn't in core. Its only 100k though... ;-)

well, that will only start to work once the series 16 images are
actually released, until then the website will keep point to the
official 15.04 release indeed :)
 
these images are betas ...

definitely also worth a bug report (though it might be tricky to detect
from within kvm that you are running inside kvm and conditionally
change the default message here)...

this is on purpose ... (you can indeed log in via ssh and use "passwd"
to set a password for the account)

Re: [Fwd: Ubuntu Core 16 beta images available]

2016-09-08 Thread Simos Xenitellis 
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@10.0.2.15
The instructions at the Snappy Start suggest to
   ssh -p 8022 ubuntu@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@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.
