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

It’s faster than virtualbox because there is lower recourse use from the base system and it uses qemu. Qemu/kvm is the fastest option for vms on Linux, but it isn’t exklusiv to qubes, you can also use it via the terminal on any distro or with a GUI like gnome boxes

It uses the Xen hypervisor, not qemu/KVM. Technically it is a Xen kernel virtualizing Linux since it is a type 1 hypervisor.

Xen uses qemu for HVM guests afaik
