yep, same. Oracle can die in a fire.

And who would take their place moving Java forward? Since Sun went down, it hardly goes over 10% of external contributions, and no one else cared about getting hold of Java 6.

I'd wager external contributions are reflecting people's opinion of Oracle. I'd never contribute to something they own.

People were already playing GTA 5 at least five years ago using VFIO/PCIe Passthrough. EDIT: Correction, it was four years ago from my few seconds of rechecking myself

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.

Amazon Corretto, Google… java and JVM run deep many big places

Has anyone had luck getting decent GUI performance (macOS host, Linux guest)? I don't need 3D, just sane 2D performance. The last time I tried this, it was so bad that I had to drastically decrease the window size to get reasonable performance. As in, it would basically lock up above a certain window size, and no reasonable amount of waiting would get it to respond. (And yes, I fiddled with all of the obvious knobs f…

I use 4K screens. Virtualbox is literally unusable at those resolutions. I have to run VMs at 1080p and upscale them in Virtualbox. At 4k, simple actions such as opening the start menu take several seconds.

VMWare does this much better, but is a pain to run on up-to-date kernels.

The situation sucks, is what I'm saying.

Oooh! Will 2022 be the year when a virtualization platform can finally run The Sims 2? ;)

VMWare has actually a decent "forward-based" GPU virtualization support. The performance is bad (on my system, around 25% of native), but for old games, it's enough. I'm hoping that VirtualBox 7.0 will have similar performance (and support; it had 3d virtualization already, but it was very poor).

The only way I've been able to get good virtualized 2D performance without providing a GPU directly to the VM has been to use a display manager where you can disable compositing. Otherwise, you end up having to use a software 3D rasterizer like LLVMpipe, which can be quite slow. The native display managers for XFCE, MATE, and (I believe) KDE allow you to disable compositing. GNOME and Unity's native display managers…

Check out VirGL and the virtio-gpu projects. Is already available in qemu if you're willing to do some work. Virtualized OpenGL (and soon Vulkan?) access to the host GPU inside the VM. e: my memory slips me, I've already run vulkan apps in qemu. > [lexi@arch-steam ~]$ vkcube > Selected GPU 0: Virtio-GPU Venus (Intel(R) UHD Graphics (CML GT2)), type: 1 Granted this was ChromeOS[0], but ultimately it's the same qemu.

Chromeos uses crosvm, not qemu. Qemu uses virgl to provide opengl, but I think vulkan is still in the works. You can use crosvm on Linux too,works pretty well, it uses a newer version of virgl to provide vulkan.

What value does vm encryption have? I’d rather encrypt my host and leave my vms unencrypted, given it would be possible to back door virtual box binaries given an unencrypted file system, or keylog keys assuming a remote breach.

You could have a VM where you do your secret stuff, and then shut it down when you are done and nobody can access it without the key.

It doesn't help against sophisticated keyloggers on the host (although I'd assume you would have a little bit of protection if you don't normally work as admin). It is more for the case that your PC gets stolen, or confiscated by authorities.

I think my PCs which shipped with full disc encryption are secure (Windows, macOS), but I never looked into it in detail. And I don't know for sure who could access it besides me (my job, Microsoft/Apple, law enforcement). My old shared desktop PC is definitely not encrypted. I only really have confidence in the Linux laptop I set up.

So for me it would be a privacy and comfort win to just have a small VM for sensitive stuff which is easy to encrypt.

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 that" like TeamViewer and WinRAR.
