This article provides tests to assist in determining whether a virtual machine running on VMware ESX/ESXi is non-responsive or otherwise inaccessible. These tests must be done while the issue is occurring. The tests might not assist with any past issues.
The services a virtual machine provides may become unresponsive or unreachable due to a number of causes, including problems with the applications or Guest OS within the virtual machine, problems with the virtual machine monitor or virtual devices, resource contention on the ESX/ESXi host, or issues with underlying storage or networking infrastructure.
For steps to isolate and address the cause of the virtual machine’s inaccessibility, see Troubleshooting a virtual machine that has stopped responding (1007819).
NOTE:- When Troubleshooting Hung Virtual Machines use the KB article :- 200583, These steps in the Knowledge Base article should only be followed for troubleshooting Virtual Machine issues like Unresponsiveness / Hang etc. This Knowledge Base article steps does not capture the Guest Operating system Logs from within the Guest OS.
If any of these tests succeed, the virtual machine is still partially functional. The tests which succeed or fail indicate which layers are functional or which must be invetigated more closely. This narrows the scope of potential causes of an issue.
