It's free and works for me, why should I stop using Virtualbox?

You're talking the CEO of a company who sued Google on the premise that header files, a descriptor file for what commands can be used and what parameters they took, should be copyrighted? The CEO who poisoned the OpenOffice community so thoroughly that the fork, LibreOffice, was founded by the leaders of OpenOffice and became the de facto standard instead of the original, and it happened overnight? That guy?

Oh. That part I didn't know.

Yeah, that was just the habit probably.

Why would anyone use it over qemu? Is this a business enterprise thing?

Bruh they're a copywrite law firm (read as patent troll) with a database and a tech company attached. Pretty much all they do is fuck other people over

Not really. Incus is a fork of LXD that's carrying the torch for community focused containers.

and what to use instead? run qemu commands and all the preparation by hand?

there's proxmox, but that's not a desktop solution.

Interesting. Reminds me of Emby and Jellyfin...

I still don't like the decisions Canonical is making.

This is why KVM is a good option, or even Hyper-V for Windows hosts. The only problem with KVM Is graphical support for paravirtualized drivers is basic at best with no full 3D acceleration that I know of for Windows guests; virtio-win isn't exactly the best option graphically and QXL to my knowledge is even more lacking, but one can just pass a hardware GPU through over vfio-pci for that.

Unfortunately for Mac hosts, Apple has no KVM/Hyper-V equivalent so your best option for virtualization there is Parallels.

(and it's honestly kinda stupid that Apple can't build their own KVM equivalent into the Darwin kernel which macOS is based on)

Proxmox is the way to go in businesses right now to replace Vmware

At first, I thought the products you were listing were "good softwares going to die". I was like "wut. Proxmox is fucking epic."

I would argue for Apache Cloudstack personally.

Though I have used and like Proxmox as well.

Yes, that’s a more correct use of “prisoners dilemma:” a choice to either cooperate or defect. Origin below, for the curious.

The dilemma

Two prisoners are interrogated in separate rooms. Each is asked to snitch in exchange for a reduced sentence.

Because they’re separated, the prisoners can’t coordinate, but each knows the other is offered the same deal and the interrogator will only offer bargains that increase their combined years of imprisonment.

For example, “house wins” if snitch gets -2 years and snitchee gets +3 years, since interrogator would net +1 year from the deal.

So what will each prisoner do?

The result

Of course, the best outcome overall is for neither to snitch, and the worst is for both to snitch.

The Nobel-Prize-winning observation was that any prisoner faced with this dilemma (once) will always net a lesser sentence if they snitch than if they don’t, no matter what the other decides.

In other words, two perfect players of this game will always arrive at the worst result (assuming they only expect to play once). This principle came to be known as the Nash equilibrium.

Applications

The result above sounds bleak because it is, but real-world analogs of this game are rarely one-offs and thus entail trust, mutuality, etc.

For example, if the prisoners expect to play this game an indeterminate number of times, the strategy above nearly always loses (the optimal strategy, in case you’re wondering, is called “tit-for-tat” and entails simply doing whatever your opponent did last round).

The study of such logic problems and the strategies to solve them is called game theory.

The not owning anything is ridiculous. We need clear regulation that makes it so companies cant do bullcrap like this. If I buy something, I own it, period.

100% agreed.

Here's a relevant Louis Rossmann video where a US Senator (Ron Wyden) officially asked the FTC to look into issues like this. I sincerely hope something comes out of this.
