VirtualBox (desktop for testing and development [Vagrant]), KVM: libvirt, Proxmox (production stuff).
Just be mindful of guest addons. (The are not foss)
Raw qemu at the command line for the one I use on a daily basis (not recommended for the average user). VirtualBox if I need to spin something up quickly but don't expect to need to keep it past the current testing cycle.
I use LXD (or Incus) containers
I've been curious about those for a while, what are they about, are they somehow better than the usual Docker/Podman conatiners?
They run a full distro rather than the minimalist that Docker containers use. You can also use them to run gui apps but that needs a bit more work to configure. I run Google Chrome sandboxed this way.
xcp-ng. except now everything is just containers on atomic fedora because it seems to fit my laziness better and doesn't require updating multiple vm os's
Replied to others with this but realized you won't get those notifications. I finally got around to releasing this, which is Debian in your browser via Docker: https://nowsci.com/webbian
KVM, QEMU, Looking Glass
VMware, Virtualbox for OSes that hate VMware, and Qemu for emulating OSes that only run on obscure platforms.
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.
