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.
Virtualbox is slow and the licensing for guest addons is nasty. It is proprietary of course and if a person in a company uses it unlicensed they will send the company a massive invoice.
I only need it for the very occasional testing of open-source software on Windows, using the precanned VM images provided by Microsoft (last I checked, they had none for qemu, or I would be using that instead). And if you're using software commercially, you'd better be damned sure you understand the licensing before setting up. A company of any size will have lawyers vetting that anyway.
In other words, I don't disagree with you, but those issues don't matter for my use case.
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.
VirtualBox (desktop for testing and development [Vagrant]), KVM: libvirt, Proxmox (production stuff).
Just be mindful of guest addons. (The are not foss)
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
I tried using virt-manager+kvm to try some stuff out the other day but I failed to set-up some crucial things. Probably me being incompetent.
Not like virtualization is a big part of my life anyway. I just wanted to try some other distros and such without rebooting.
If I were to get serious about virtualization I'd need to build a new PC with a second GPU. Then I could stop dual-booting and do everything with VMs. But it'd only be worth it to get serious about learning how to virtualize stuff if I were to do that.
You can single pass through but it feels more like your using one os but if that's the case wouldn't dual booting be better
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
I'm using systemd-nspawn or Bubblewrap, depending on the scenario.
Those are container platforms not virtualization
Yep. I found I don't have much use for a full-blown VM, whereas there's plenty of argument for isolating my browser from ~/.ssh/id_*.
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.
