Hi All,
We run hundreds of Windows and Linux VMs in clustered and non-clustered environments. However, we're having issues with one particular VM that regularly restarts itself. The environment the problem VM is running in is a Windows 2012 R2 cluster.
The event log within the VM provides no BSOD information, the only entry of any note:
The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.
Therefore, I don't believe that the actual OS within the VM (Windows 2008 R2) is crashing.
The cluster log shows only a single entry:
Cluster resource 'Virtual Machine vps.xxxxxx.com' of type 'Virtual Machine' in clustered role 'vps.xxxxxx.com' failed.
Based on the failure policies for the resource and role, the cluster service may try to bring the resource online on this node or move the group to another node of the cluster and then restart it. Check the resource and group state using Failover Cluster
Manager or the Get-ClusterResource Windows PowerShell cmdlet.
How can I debug this? I've added extra RAM to it, and moved it to other nodes and other storage but the problem continues to occur.
Thanks
Will
