Sun and SGI were once profitable but once Linux gained traction it was over. They had no option to be assimilated by the Borg.
Ironically they were contributors to their own downfall.

Well yeah, but that requires a whole second GPU. A virtual GPU guest driver that translates to calls to the host GPU would be a godsend. Hard to tell if that's what's advertised in these release notes, but if so, then at least older games might finally exhibit some decent performance.
You _can_ use various hooks to dynamically bind and unbind on a single GPU system but that would be another degree of difficulty for newcomers (on top of potential buginess throughout the stack). As to the latter part of your first sentence, I believe that virtio-gl works in the manner you describe. Thought it is Linux only. I have experimented with it on Proxmox and it works well enough.
For example, AMD GPUs don't support rebar (took a while to figure out), and they used to have (I don't know if it's been definitely solved) a problem with reset, which caused random lockups when exiting the VM.
Additionally, power saving/device ownership must be handled. Which means: either one terminates the X session each time before starting/after stopping the VM (so X will handle the power management), or they leave the card owned by the vfio driver (but this makes the card run hot while sitting doing nothing, because the vfio driver doesn't handle the power management), or they swap drivers on the fly hoping that it will work fine (on nvidia, it's not a stable strategy; no idea on AMD).
And these are just a few issues. I've experienced others in the past, and it's very frustrating and time consuming.
With all these problems, a combination of dual boot (for demanding 3d tasks) and VMWare (for light ones) is much simpler, and stable. I hope to replace VMWare with VirtualBox for the latter use case.

I find libvirtd to be fine other than sound when compared to virtualbox. I never did get sound to not be laggy and jerky in qemu on linux hosts.
For a Linux guest, I just forward the host's pulseaudio socket over ssh. ssh -R /run/user/1000/pulse/native:/run/user/1000/pulse/native -X the-vm the-audio-using-command I use this VM for occasional video watching and for video conferencing and haven't had any audio problems.
Oooh! Will 2022 be the year when a virtualization platform can finally run The Sims 2? ;)
Is there a way to stop vbox from phoning home to Oracle?
Is there a documented case of Oracle suing somebody for using VirtualBox on a company network? They have no way of knowing if it is some private person on a guest WiFi or if it is used in production. I know Oracle is famously litigious, but I've only heard about this in cases of CAD software. I'm all for being professional and paying for your tools, but it seems VirtualBox is in the class of "haha I'm not paying for…
I thought VirtualBox was free/opensource to use, even for comercial use. I will change to kvm/qemu
What’s the alternative for host on windows?
VirtualBox is cross-platform; runs on Linux, Mac, Windows. Images are portable. As a sibling notes, the Windows built-in is Hyper-V. Or if you don’t like your money, VMWare.
Oracle was responsible for my first complaint, while I was doing my first internship in the US. Because once I used my private laptop with the VirtualBox Extension Pack while connected to the work network. The incredible legal/licensing team got in touch because they identified this use. Since than I avoid Oracle like plague.
I used to use VirtualBox heavily about 15 years ago and it seemed to work well back then for Linux hosts and guests.
Since then I've used it sporadically, using it for Linux guests on Windows 7/8/10 as well as Windows XP and 7 on higher Windows.
A few days ago I tried to install Windows 10 guest (4cores/8GB RAM) on host Windows 10 host(32GB/6cores)
This was on VirtualBox 6.3 and the performance was really slow.
Installation took an hour - using same NVME Samsung 980Pro for official Microsoft windows.iso and installation.
After installation boot is slowish - a few minutes, and guest system feels like using an Atom processor not i7.
