I have a mac mini with two monitors. On the main monitor I normally keep two desktops and on the second there is only one. I have been noticing that the main monitor seems to add more desktops by itself.
So I am not sure if I might be pushing some sort of shortcut to create another desktop or if there is actually something else happening.
If anyone has any ideas or if if you have had the same issue and fixed it I'd really appreciate your help.
You wouldn't need two VMs running, merely one running while you use the host OS X would accomplish what you want. It would be easier to give a suggestion based on a more detailed explanation of what you wish to do or accomplish.
If you want something to not disappear when changing spaces try using the "assign to all" option.
From comments below, option for multiple docks
I don't have an external monitor to test this on, but you could look at an app called Swapp that purports to be able to swap the contents of an external screen onto your main display. I'm not sure if it works with more than 1 external monitor, but in theory you might be able to switch to a 2nd desktop on your MBP, and swap the windows from an external monitor onto it, hopefully being able to repeat the trick with a 3rd monitor on a 3rd desktop space.
There is also Display maid which looks similar.
Both have free trials.
You could also try this relatively simple but manual trick to shove windows to another desktop space, either before removing your external monitors or after:
Enable Desktop Space control keys in System Preferences > Keyboard > Keyboard Shortcuts > Mission Control, check the boxes as follows:
To move windows, click and hold on any window titlebar and hit Control+2, Control+1, or Control+3 to instantly bring the chosen window to the desktop corresponding to the keyboard shortcut

This link explains it. Its a new(ish) feature. You can zoom to mission control (f3) or for those with a MacBook, and you have new haptic track pad, you just three finger scroll up and if you move your cursor to the top right corner of your screen you will see a plus sign appear. Click on this to add a new desktop.
You can get rid of it by Going back to mission control again (f3), where you will see all open apps, and you can just close it (them) by hovering your cursor over it and an x will appear on top left corner it, or anything else, out from there. If you're in mission control it's easy to inadvertently create additional desktops if you thro your cursor up out of your way.., I've done it a few times.
It can be super useful when you want one open for work and one for play, but that I guess is not the point. Easy to get and get rid of though. Many good publications on how to make most of the feature if you ever want to.
