Hey future me! I know it’s not that often that you require it, but there are a lot of virtualization solutions out there that use qemu as a backend machine translator.
It isn’t the most optimal vm environment when used on it’s own, but it provides some useful features that other projects build upon.
There’s KVM, Xen-HVM and when you need it in a pinch, raw qemu itself. But there’s something that you’ve never gotten right. Not without external tools and graphical managers. Networking.
