This would include anything created in such a VM, unfortunately. So, if you're not worried about that, it's a great separation of concerns. If you are developing new IP, though, you would want to be very careful about using your work machine.

I'm even nervous about logging into a personal machine via SSH from my corporate laptop, if I'm honest. Might not be enough to legally take ownership, but its probably enough to draw you into a protracted legal battle.
