VMWare Virtual Machine will not Start in vCenter

So I was asked by a client to do up “hardware upgrades” on one of their virtual machines. This VM is not production and is not running anything at the moment, but will soon become an SQL Server running an application. So I went and powered off the VM, logged into the C# vSphere client (they are running vSphere 6.0), and doubled the memory as requested by the client.

After making the change I went to power on the VM and I get presented with this pop up error message from VMWare

The message itself seems pretty generic but I have actually seen this one before. This error has to do with  an issue with the management agents on  your ESXi host.

I followed the instructions found on this KB article but it did not resolve my issue. I also found this KB article which might yield better results but as this whole environment is production, I will need to wait to test that.


In order to get this VM powered back online, I needed to log directly into the virtual host and power on the machine.

The VM powered on with no issues.

I hope you find this helpful and I will update this when I have a solution.
