If you did not see a table which looked like
+---------------------+-------------------------------------------
| name                | operation-1327681189228-4b784dda81d58-b99dd05c |
| status              | DONE                                           |
| target              | ${VM}
 ...
| operationType       | insert                                         |

Then the vm name may be running already. You will have to delete it to
recreate it with different atttributes or move it to a different zone.

Check ./vm_status.sh to wait until the status is RUNNING


SSH into the master with:
  gcutil --project=google.com:chromecompute ssh --ssh_user=default skia-telemetry-master
and run:
  * Make sure the scratch disk on the master is mounted correctly with 'df -v'.
  * sudo chmod 777 ~/.gsutil
  * Install the latest version of gcutil and then run
    gcutil --project=google.com:chromecompute ssh --ssh_user=default skia-telemetry-worker1
to setup gcutil promptless authentication from the master to its workers.
  * Add a ~/.netrc by generating a new password from https://chromium.googlesource.com/
  * Run 'cd /home/default/skia-repo; rm -rf trunk && gclient sync'
  * Run the following to be able to download massive files from gsutil:
      sudo apt-get install lua5.1 gcc python-dev python-setuptools && sudo easy_install -U pip && sudo pip install setuptools --no-use-wheel --upgrade && sudo pip install -U crcmod
  * Install the following missing packages:
      sudo apt-get install python-django
  * Run vm_recover_slaves_from_crashes.sh
  * Verify that all slaves are healthy by running:
      bash vm_run_command_with_output_on_slaves.sh "ls -l storage/"
  * Start the /home/default/skia-repo/buildbot/compute_engine_scripts/telemetry/telemetry_master_scripts/appengine_poller.py script.
