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.

Technically no, both use kvm virtualization which is included in the Linux kernal, so both are "bare metal hypervisors" other wise know as class 1 hypervisors. Distinctions can be confusing 😂
Oh dear... I really thought I understood what bare metal means... But looks like this is beyond my tech comprehension
Bare metal is "kernel running on hardware" I think. KVM is a kernel feature, so the virtualization is done in kernel space (?) and on the hardware.
Well this can be a starting point of a rabbit hole. Time to spend hours reading stuff that I don't really understand.
TL;DR: use what is in the kernel, without strange out of tree kernel modules like for VirtualBox, and use KVM, i.e. on fedora
virt-manager qemu qemu-kvm
