The VM I'm using for VCenter seems to shutdown on it's own anytime someone isn't paying attention to it. It's done this a number of times, most recently about 10 mins ago. I had gotten up from the server to talk to an associate and when I came back the server had shut down. In the events, I get a simple log saying "Virtual Machine on localhost.localdomain is powered off," and the task was initiated by "User" Neither my ESX servers or VCenter have a user named User, nor does my domain. My network isn't connected to the internet, and currently exists in one room, so no one is pranking me. Has anyone seen this before? It's more an annoyance than anything, but anyway to prevent it from happening would be helpful.
As some background, the network was stood up approx 3 weeks ago and this has been happening the whole time. The only times it's been happening is when someone is actually working on VMs through the consoles, and then walks away for more than 5 minutes. This most recent time I locked my workstation before leaving. To the best of my knowledge, it's never just dropped out from under anyone yet. And it's ONLY the VCenter VM. All the other ones are stable.
In the meantime I've removed everything from the "Shut down system" security key, but I'd like to be able to shut the system down without having the change a setting every time. I also checked the event logs but I'm still getting familiar with 2008 and nothing jumped out at me.
