UTAH fails to install oem with raring desktop

[Para Siva]

The raring desktop OEM preseeded installations are failing and it could be noticed that the installation does not proceed after the reboot step in oem installations.

Attached is the syslog from the failed job.

The impacted jobs are,
https://jenkins.qa.ubuntu.com/view/Raring/view/Smoke%20Testing/job/raring-desktop-amd64-smoke-oem/7/console
https://jenkins.qa.ubuntu.com/view/Raring/view/Smoke%20Testing/job/raring-desktop-i386-smoke-oem/4/console

Though these jobs have the post installation test results, the installation itself is not complete and the post installation tests seem to have run before the full oem installation

Manual OEM installations on hardware and VMs are working fine and even preseeded installations without using utah are working fine.
Please see attached file called 'passed' for the syslog of a passed preseeded installation

Passed syslog for preseeded oem installation without using UTAH for comparison if needed

[Para Siva (psivaa)]

The passed installation was using the combination of preseeds
http://bazaar.launchpad.net/~ubuntu-server-iso-testing-dev/+junk/desktop-tests-quantal/view/head:/preseeds-common/base
and
http://bazaar.launchpad.net/~ubuntu-server-iso-testing-dev/+junk/desktop-tests-quantal/view/head:/test_cases/oem/preseed

Adding these two lines to the preseed made one test pass:
d-i oem-config/enable boolean true
d-i oem-config/id string USIT_OEM
The remaining failure was this:
  stderr: |-

.desktop) exists

I don't see that symlink somewhere else, so I'm going to see if using the oem user or at least creating that home directory will make a difference.

I've been testing with an alternate config file that changes the user to 'oem' instead of 'utah'. The first thing I found with this is that the sshprivatekey defaults to the oem user's home directory, so I had to change that to point to the utah user in the same config file. After that, I realized the uploadfiles method of the SSHMixin class doesn't specify a username, so all files are uploaded as the user running the script, in this case, utah. This fails when there is no utah user, but confusingly throws this exception:
paramiko.SSHException: not a valid DSA private key file
I'm going to test a utah code change to see if that in conjunction with the updated config file and the preseed changes will fix this.

[Max Brustkern (nuclearbob)]

I've submitted an additional merge proposal to allow the use of launchpad URLs for utah config files. I'm testing these changes now. If they work for this test, I'll propose a merge against the desktop tests branch that updates the preseed and adds the appropriate config file, and updates the job generation script to include this file.

Just realized that the build is broken because the import for url_argument
fails when using `config.py` at build time.

Quick update, as of today, the only remaining failure related to this is the missing desktop link for preparing shipping to end user. I manually checked this on todays image and confirmed that the desktop link *is* present as it should be. Talked to Max this morning and he said it's just because we're using the utah user instead of the oem user it expects. He has a fix coming for that soon.
