You don't need a qvm. Just create a server with /devmap <map>.
No what you are thinking of only allows you to do Give funds give all and give health.
What i'm talking about is "give turret" or "give flamer" or "give level4" the thing about these is that if you are human give flamer gives you a flamethrower and you get to keep other weapon also
On top of this you can go dretch and then do "give mdriver" and youd be a dretch that can still wallwalk but that can use a massdriver. no cost to evos or credits btw.
Sounds crazy but you have to try it to know what i'm talking about...
