Kata containers and qemu-mini in Fedora

Kata Containers is a way to run containers in individual virtual machines, in order to provide better isolation. Bringing this package to Fedora ran into a number of interesting issues, with enough moving parts to make things slow and difficult. This is a tale of bad interaction between the kernel (e.g. cgroupsv2), docker (e.g. docker vs. moby vs. podman) and Go (how languages with their own packaging system cause interesting issues for distros like Fedora).

Running many small virtual machines led us to also consider a "mini" version of qemu, i.e. a version stripped from anything that is unnecessary to run recent versions of Linux as guests.
