I created a high performance vm and everything is fine. I stop the virtual machine and make edits to it and again runs correctly. I shutdown the vm and click the edit tab to look at what I changed and it is now back to the defaults and my edits are gone. Is this now the intended result. I was using the same settings in 4.3 and never exhibited this behavior. What I have observed so for is that I disabled Headless, disabled cpu pinning, and changed numa config. When I shutdown the vm, they revert to default of Headless enabled, cpu pinning is set and the numa config changed. This is not what I expect to happen. Has anyone else noticed this behavior?
