Yesterday morning when the HA Monitoring turned off, the VM "hang" so I need to power off it and turn it on again. >If it is disabled right now there should be no issues right now. I am sorry, i am just a beginner and i dont know what to check at the first place.Ĭheck Application and system tabs, then filter by errors and warning for the timeframe in which the error courred. > Have you checked windows Event Viewer? What do you see?
You can do a manual test to determine this: go to the VM OS and stop the VMWare tools service-Īdditionaly you can re-install vmware tools in order to discard vmware tools issues I want to know, is it because the VMtools or because of the VM it self? but when the VM freeze, the VMtools not running. Yes, its running when the VM does not freeze. VMXNET3 is the recommended one for Windows Server 2012 Virtual machines can have different types of Virtual NIC's (network cards) >Have you checked if VMXNET3 NIC is installed? Perfcharts are performance charts, graphics that indicate how a VM is performing go to -> VM-> mointor -> performance i will find it out soonĮsxtop is similar to linux's top but with specififc metrics to VMware -> ESXTOP - Yellow Bricks | Yellow BricksĬPU ready and balloning are symptoms of cpu and resource contention which can bring a VM down I am sorry, i dont know what is esxtop or perftcharts. >Have you ran an esxtop or a perfcharts on the VM checking for CPU ready or balloning If it is disabled right now there should be no issues right now. I want to know exactly is it an error of the Center or the VM >Is VM monitoring enabled on the cluster? Thank You so much to join the discussion sir I will check it when i have the permission. > I am sorry sir, i can not check in to the VM without permission. we could not ping the VM too.Īre there any messages in the Windows event logs for the times when things go wrong? >Yes sir, I know the VM was "hang" because the User told me that the VM is down. Is there a pattern to when the "hang" or "freeze" happens? How do you know or observe the "hang" or "freeze" has taken place?
If I'm not mistaken, there are another services running in the VM (I don't have permission to enter the VM) > I just know that DHCP service is light now, thank you. The DHCP server service is very light, so 4 vCPUs and 8Gb memory sounds very excessive - are you sure there are no other applications or services active within Windows? Windows Server 2012 R2 is fully supported on ESXi 6.7, confirmed on pages 127-128 of this: You can also check this KB to identify what causes the VM to be rebooted: VMware Knowledge BaseĪlso you can follow the next KB to see VMware Tools logs in case the reason were the unresponsiveness of them: VMware Knowledge Base Try to uninstall the VMware Tools and re-install the newly ones (First take an snapshot).Some recommendations to start from my side are: From VMware perspective you can open the VM files browsing the datastore and search for the vmware.log that can give you some information about the VM and its operations.įrom inside Windows you can check the Event Viewer to identify some issues. You can check multiple spots to see why is crashing. Windows Server 2012 R2 is completely stable in that version even much more before in previous versions. The VM isn’t generating any storage or network IO (for 120 seconds by default).That VMs VMware Tools heartbeats are not received in a set period of time).Assuming that you have VM Monitoring enabled in the vSphere HA configurations these are the reasons of why the VM is restarting itself:
