I use VMware vSphere Client to open up and manage my districts virtual servers that reside on a Nutanix 4 node appliance. I have noticed that I am getting alot of my virtual machines are not accessible when staff members try to get to their shared drives or printers (reside on virtual servers) in the mornings. In the vSphere client it shows they are running but if I try to open the servers console it is just a black screen. I have to restart the guest to get the server to boot up correctly and then the resources are available again. This has been happening alot lately and need to find out what is causing them to go offline and needing to be reset. We are running v5.5. The logs do not show any errors.
