Just an FYI,
While doing some acceptance testing before deploying a new version of the dispatcher to production I noticed a bug:
https://bugs.launchpad.net/lava-dispatcher/+bug/1032467
I'm not sure how our external users of LAVA have things configured, but this could potentially cause you some breakage. I worked around our issue in Linaro by adding:
tester_hostname = linaro
to the device-defaults.conf file.
