Report: that worked until GCC started compiling. Turns out no, the scheduler cannot handle it. VM was already isolated to one NUMA node, so now I'm sending emerge off to the other one (CPUs only, let's let it use all free RAM).

Now the question is, how terrible of an idea is it to try playing VR games on my Threadripper in a VM while it's compiling Gentoo packages? I mean, emerge is niced, I have an NVMe drive, and RAM to spare. It *should* work... right? The scheduler *should* handle it, right? Right?

Yup, that worked fine. A few dropped frames here and there while compiles were pegging one side, but nothing terrible. Beat Saber plays fine.

Ha! Give it a try. I only ever used to run into things bogging down when disk I/O got queued to hell, but that was back in the spinning rust days so---

Which virtualization software? I use VirtualBox and the 3D pass through just stinks. I had worse luck with VMWare. When thinking of doing VR dev I was afraid I'd have to dump to a physical Windows box.

Qemu with PCI passthrough for both GPU and USB. Virtual peripherals obviously aren't going to work for either of those. I already know it works well when I'm *not* building packages :)

Setting emerge MAKEOPTS to use just enough cores & allocate sufficient cores/RAM to VM, sparing some cores for system. Meanwhile reading cgroups & packet scheduler wikis for other resources. Finally the day will end and neither the packages are complied nor any game played

Sounds like the start of a anti-hero protagonist movie

I have cgroups set up so that while the VM is running it isolates a NUMA node for it (both CPU and RAM) does mean that it takes like 20 seconds to start up while it copies everything off those sticks, though

Only one way to find out.
