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.

Is Qubes any more efficient in resource usage than a typical VM? (lemmy.ml)

Privacy benefits aside, does qubes run better than a typical vm like virtualbox? I tend to fiddle with distros a lot and I feel qubes might be a good choice, though I'm wondering about how efficient it is

for me i will likely play some games or use proprietary apps in windows or something and swap back to linux. i also develop for linux sometimes so being able to swap distros quickly and with good efficiency while being able to share files easily would be nice.

i dont know how viable qubes is for this use case. i like the concept of privacy but i dont need 100% lockdown for each app.

i hate dual booting with a passion, and i also hate how much my base OS interferes with the operation of a virtualized os.

3d acceleration in qubes is very experimental. maybe not the best for gaming. You can do it, but your going to be elbows deep in virtio configurations

We do not provide GPU virtualization for Qubes. This is mostly a security decision, as implementing such a feature would most likely introduce a great deal of complexity into the GUI virtualization infrastructure. However, Qubes does allow for the use of accelerated graphics (e.g. OpenGL) in dom0’s Window Manager, so all the fancy desktop effects should still work. App qubes use a software-only (CPU-based) implementation of OpenGL, which may be good enough for basic games and applications.

For further discussion about the potential for GPU passthrough on Xen/Qubes, please see the following threads:

happen to know of any distros that dont have this limitation and operate similarly to qubes? i havent heard of anything i know its a longshot 🙃

but maybe i could work on programming and making this a bit smoother if i like the rest of what qubes offers

Qubes is unique

You could 100% play games on qubes if you have two graphics cards, or a integrated graphics on the CPU, and then have the GPU dedicated to a specific VM.

However, at that point, you might as well just use moonlight and sunshine and stream your game over the network.

Sunshine can run inside of a VM it just needs access to a GPU.

i do have integrated graphics and a gpu, though i dont know if the bios has one set to run independently or something

Then you can game no problem.

Pass through the GPU to one VM.

You should use KVM for games

yeah ive been considering it
