I wonder which would give better performance for a VM:
Windows host - Linux guest or
Linux host - Windows guest

It feels like the obvious choice would be Linux host - Windows guest, since Linux has a lot going for it for hosting VMs, but Windows is so resource intensive, that I'm certain in a VM environment, where resources are more limited, Linux would always perform better than Windows.

@hitlerswaifu
You kinda need an extra GPU and a monitor hooked up to it for that though, right?

@alyx not true

You can use single GPU passthrough and pass your main GPU also looking glass exists

@hitlerswaifu
I always forget about Looking Glass. Heard the name a bunch, but never looked into it.

@alyx The downside with single GPU is that you can't use both at the same time however you can shutdown and your back at Linux
@alyx Might be able to get software rendering over VNC? I haven't tried to do this

@hitlerswaifu
I'm looking up some tutorials out of curiosity, and.... wtf? A lot of what prevents me from testing this out is always the hackerish things they have you do. Yeah, I'm not gonna do that. I'm not gonna mess around with Grub or my kernal with configurations I have no clue about, nor will I mess around with a GPU bios file that while it seems I'm not flashing, I still don't understand its purpose.

@alyx I was able to do it and I'm retarded you should be able to do so as well

@hitlerswaifu
I'm not really scared that I'm not able to do it. My concern is more, will I able to safely undo everything without borking something, if I want to.

@alyx I've had no problems the 3 times I've done it on Arch Linux
@alyx Provided you use hardware virtualization features, either will have pretty much the same CPU performance.

Btw, Linux is only a kernel, did you mean GNU/Linux?

If you're using an interpreter for "virtualization" for some reason, then qemu on GNU/Linux will run faster than any system emulator on Windows.


As for graphics performance, that depends on the quality of the graphics drivers in both the guest and the host, or if you use GPU pass-through.

Proprietary graphics drivers tend to be of exceedingly poor quality, while polished free software drivers like mesa are of excellent quality.

Why use the proprietary malware known as windows anyway? GNU depreciated it years ago.
