[Status] Mixed [Applies to] Active and stored environments [Description] 
Not all virtual machines in the environment are in the same state. Some of them are in Stopped, Paused, or Running states, whereas others might be in some form of Failed states. This might occur if the state of a virtual machine was changed bypassing Lab Management. For example, if you restart a virtual machine and you are connected to it, the state of the environment becomes Mixed.
