QEMU along with Bochs were my first tries getting into virtualization / emulation way back (maybe around early 2000s? I can't remember!). Although the emulation / virtualization market already grew larger with more and more options available today, QEMU was (and still is) one of the most awesome projects out there.

A lot of the options (especially the free ones) are either using qemu or using ideas that were developed early (not actually first) for qemu like virtio. There are just a lot more layers on top these days, and not always for the better.

  Proxmox is great as a FOSS hypervisor, but their docs for doing pretty much anything advanced are just "here's a qemu command".

    hmm, if you refer to the `qm` command, that is not from Qemu itself but a Proxomx CLI tool :) https://git.proxmox.com/?p=qemu-server.git;a=blob;f=PVE/CLI/qm.pm;h=b105830fa6f558e0efae0eb6efe66a764cc6b066;hb=HEAD https://git.proxmox.com/?p=qemu-server.git;a=blob;f=PVE/CLI/...

Back in the day I ran Bochs in all its 4 Bogomips glory on a university IP address and went to IRC channels where script kiddies were "trading root". I let them go first, and watched through an instrumented terminal how they clumsily installed a rootkit, then inevitably refused to give anything in return and laughed calling me a noob. Their laughter was short lived. I had even spent quite a bit of effort kludging the kernel to report much higher specs than Bochs could deliver, but all that effort was wasted because no one knew how to check.

QEMU is used in basically every single hardware vendor today and has been since I've been in virtualization/containerization tech (2010+). I've only seen Vmware (gsx/esx) at Windows shops for things like big Exchange clusters, etc. Every CDN I've worked at used qemu.

  There's still a lot of Xen out there
