Not everything uses qemu. Some do. More use KVM. Not everything does.

Example: https://firecracker-microvm.github.io/

I've found QEMUs microvm to be faster at boot while having nicer tooling and a cleaner upgrade path if needing more features. Aside from hype I'm actually not sure why anyone would still use firecracker.

Mainly because of the much larger attack surface of QEMU.

I can't quantify how much of that surface is also reduced with the microvm machine vs other parts of QEMU vs Firecracker... But fair enough point.
