DaanHoogland opened a new issue #3741: power sync marks missing VMs as stopped URL: https://github.com/apache/cloudstack/issues/3741 <!-- Verify first that your issue/request is not already reported on GitHub. Also test if the latest release and master branch are affected too. Always add information AFTER of these HTML comments, but no need to delete the comments. --> Out of band migration can cause VMs to be stopped, that shouldn't be. ##### ISSUE TYPE <!-- Pick one below and delete the rest --> * Bug Report * Improvement Request ##### COMPONENT NAME <!-- Categorize the issue, e.g. API, VR, VPN, UI, etc. --> ~~~ ~~~ ##### CLOUDSTACK VERSION <!-- New line separated list of affected versions, commit ID for issues on master branch. --> ~~~ ~~~ ##### CONFIGURATION <!-- Information about the configuration if relevant, e.g. basic network, advanced networking, etc. N/A otherwise --> ##### OS / ENVIRONMENT <!-- Information about the environment if relevant, N/A otherwise --> ##### SUMMARY <!-- Explain the problem/feature briefly --> The issue in the title occurs when an out of band migration takes place, for instance by a third party DRS system (vmware build in being the culprit in this case). The sequence that occurs is such: - VM migrates - it's old host reports its VMs - cloudstack marks the VM stopped - the new host reports its VMS This is not specific to a hypervisor in its logic so I think it needs a generic solution. An easy solution is to add a state missing to the fsm for VMs, but that gives extra problems in cases of HA enabled VMs. ##### STEPS TO REPRODUCE <!-- For bugs, show exactly how to reproduce the problem, using a minimal test-case. Use Screenshots if accurate. For new features, show how the feature would be used. --> <!-- Paste example playbooks or commands between quotes below --> ~~~ The issue has a timing facet and as such is hard to replay reliably. As shown in the description. ~~~ <!-- You can also paste gist.github.com links for larger files --> ##### EXPECTED RESULTS <!-- What did you expect to happen when running the steps above? --> ~~~ VM keeps running and re-appears to cloudstack ~~~ ##### ACTUAL RESULTS <!-- What actually happened? --> <!-- Paste verbatim command output between quotes below --> ~~~ VM gets marked as stopped and an abundant StopCommand is send to the hypervisor. In theory this can be the old and the new hypervisor, depending on timing. ~~~
