From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Gaming in Proxmox VM, feasible? (lemmy.ml)

I'm considering to switch to Proxmox for my main PC, run a Windows VM on top and passthrough the GPU to play games. However, I heard anti-cheates aren't that friendly to VMs. Had anyone tried this? Thanks.

What is wrong with using virtualbox?

[–] wildbus8979@sh.itjust.works 6 points 1 year ago* (last edited 1 year ago) (1 children)

It's subpar, closed source, kernel module installing, type 2 virtualization that makes users believe VMs are slow, when in fact Type 1 hypervisors usually achieve near 98% efficiency. And too boot it means that open-source projects like virt-manager don't get the usership they deserve and need to continue being maintained.

There is legit not a single reason to use it on Linux, and there hasn't been in well over a decade.

Wow I didn’t even know it was closed source. Thanks for pointing this out, I will definitely be getting virt-manager.

It's not entirely closed source, but the extension packs are. The other reason are the main one that should make you switch.

I am already spinning up a Debian vm. I had a minor issue with file permissions but it it is working great now and is definitely faster than I remember virtualbox being. I am so glad I saw your comment and I would switch to this even if Richard Stallman himself wrote Virtualbox and all the extensions.

It's also a whole lot more flexible. And will easily do full PCIe passthrough with some more advance configuration. virt-manager even works remotely over SSH if you have another machine you want to run your VMs on!

GPU passthrough was the next thing I tried! Do you know any good tutorials? The one I found tells me to do mkinitcpio but I don’t seem to have that. I think I mentioned this is Debian but in case I forgot its Debian.

I don't have a specific guide for you, but a good place to start is: https://wiki.debian.org/VGAPassthrough
