Looking...

The lab machines appear to be healthy and ready to accept tests in the lab:
atest host list -b 'board:nyan_big,pool:cq'

However, it appears that everything is failing on the provisioning stage and then aborting.  E.g.
https://viceroy.corp.google.com/chromeos/build_details?build_id=2230984

Not sure where this is failing though during provisioning.  

Going to mark as nyan_big-paladin as experimental for now until the bug can be resolved.

Basic debug strategy...

Attempting to run directly with current failing build.

Cmd:
./run_suite.py --build nyan_big-paladin/R66-10331.0.0-rc1 --board nyan_big --suite_name provision --pool cq --file_bugs False --priority CQ --timeout_mins 30 --retry True --max_retries 5 --minimum_duts 4
Result:
http://cautotest/afe/#tab_id=view_job&object_id=171651181


If this fails, going to attempt to run with previous build that succeeded to try and narrow if infra issue or an actual issue with the build.

Previous successful build:
nyan_big-paladin/R66-10324.0.0-rc1

oh it's experimental already, I was just going to say we should do taht
