I'm considering renting a dedicated AX server at hetzner.de. Those are built with Ryzen 1700X (more powerful ones with threadripper) which has no graphics whatsoever.
That server would be running VirtualBox guests. I need some guests to be Windows & Ubuntu desktops. I was planning to simply enable VirtualBox's RDP display servers for them.
I have no way of testing this scenario as I currently have no computers available completely without graphics.
Hetzner's tech support says that this should not be an issue and I should go ahead without worries, but unfortunately I'm old enough to remember what happened when I first replaced my trusted Tseng ET4000 with an actual 2D accelerator (my machine took off like a rocket :) ).
Will this setup even work? I mean, without graphics acceleration, I'm guessing the best I can get is high CPU usage running unaccelerated graphics, right?
Edit (after jumping into it): well, I'm running Windows & Ubuntu guests in there without issues. No significant additional CPU usage even though graphics card in there is purely a 2D accelerator (SM 750). Additionally it's running a dozen or so servers (ubuntu based), leaving me plenty of CPU & RAM resources to play with. I'm happy :)
