Alternatives to VirtualBox?
(lemm.ee)
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.

I don’t know if it’s more resource-efficient, but when I wanted to start using VMs for work, I knew VirtualBox would not be a viable choice (thanks to Oracle and their horrible licensing), so I chose GNOME Boxes and have been pretty happy with it. I didn’t do any tests so I can’t say for certain , but it doesn’t seem like the resource consumption is that much different.
