Licensing and Windows 10 test VM

Just a quick one. I've got a VM with the Win 10 preview running on it for no other reason than that I'm curious. I've installed Opus on there but not plugged in my licence. If I've got my licence installed on two real machines (desktop and laptop) and also on my memory stick, what would happen if I installed it on the VM as well? What's the official policy on sharing a licence with a VM and does it make a difference that it's only a temporary test system?

If the VM is running on the same machine as one of your main Opus licences, and none of the machines are shared-use terminal servers or similar, then you can use your existing licence.

The exact details are in the licence agreement at the start of the manual, which has a part about virtual machines.

OK, thanks for that.
