I am running FlightGear in a virtual box alongside a number of other processes and I find that when I run those processes, FlightGear will give me the message:

[bash-1]    93.50 [ALRT]:systems    Error drawing more current than available!

I am aware this is due to there being insufficient computing power in my virtual box (according to FlightGear). I have tried to turn off as many settings as possible in FlightGear and have given lots of resources to my virtual box, however this hasn't worked and my Guest load is only at 20% anyway. I am only using FlightGear for visualisation.

Is this an important issue that is likely to cause problems and if so, what other methods could be used to resolve it? If this issue is not important, how do I disable this message?
