This was the message that greeted me after upgrading my ESXi Hypervisor with Free license to 5.5.
I’ve applied an Enterprise license to see if there’s a difference to the host license applied and there’s no change to the behaviour.
It seems if you don’t want the hassle of using a CLI to interact with your VM’s on a Hypervisor license, DO NOT UPGRADE THE VIRTUAL HARDWARE OF YOUR VMs to Version 10 hardware. Unless you’re running vCenter of course.
I’m unable to see a way round this to restore the use of the vSphere Client as a tool to modify the settings of the VM, and let’s be clear, all I want to do is change the vSwitch a VM is connected to as my LAB ESXi box is hooked up to four different switches and I move the VM’s around to recreate different scenarios.
I’m gutted. I’ll update if I find anything to help or back myself out of this mess.
