XenServer CI Admin Tips

Auth is via ssh-keys, please request access in the XenAPI team meeting, if you want to help.

Main box:

• 166.78.153.192

Services that should be running:

• citrix-ci-gerritwatch: Watches the gerrit stream and adds jobs to the queue
  • Logs: /var/log/citrix-ci-gerritwatch.log
  • (Re)start: (re)start citrix-ci-gerritwatch
• citrix-ci: Progresses jobs through the lifecycle (see below)
  • Logs: /var/log/citrix-ci.log
  • (Re)start: (re)start citrix-ci
• nodepool: Provisions VMs to use in the tests
  • Logs: /var/log/nodepool/nodepool.log, /var/log/nodepool/debug.log
  • (Re)start: killall nodepool; rm /var/run/nodepool/nodepool.pid; start nodepool

Useful commands

• osci-view list: Gives current queue, what is running etc. Shouldn't have jobs in here that are 'older' than 2 hours unless they are 'Finished'.
• nodepool list: Gives a list of the currently available nodes. Should have some nodes that are 'Ready' or 'Building'

VM lifecycle

• Queued -> Running: citrix-ci job has got a new node from nodepool (nodepool list will show it as 'held')
• Running -> Collecting: Job has finished; citrix-ci has changed state to Collecting - waiting on log collection thread
• Collecting -> Collected: Log collection thread has posted logs to swift and updated job with logs URL
• Collected -> Finished: Citrix-ci has posted to gerrit and the job is now complete
• <anything> -> Obsolete: a new job for the same change (recheck or new patchset) has been added

Code

• http://git.openstack.org/cgit/stackforge/xenapi-os-testing/ (although currently using https://github.com/citrix-openstack/xenapi-os-testing)
  • Actual job runner; downloaded by openstack-citrix-ci/osci/tests/test_instructions.py
• citrix-ci: https://github.com/citrix-openstack/openstack-citrix-ci
  • Workflow manager
