Show HN: Isolated microVM-based self-hosted GitHub runners
This project creates self-hosted (ephemeral) GitHub runners based on krunvm [1]. krunvm creates microVMs, so the project enables fully isolated runners inside your infrastruture. MicroVMs boot fast, providing an experience close to running containers. The project starts VMs based on the multi-platform OCI images that it creates -- ubuntu [2](default) or fedora [3]. The default is to create far-less capable runners than the GitHub runners, but most settings are similar to when running at GitHub: same user ID, member of the `docker` group, password-less `sudo`, etc. Since krunvm runs on MacOS, this should also run on MacOS -- although I haven't been able to test it: reports and/or PRs are welcome.

How to create a kvm virtual machine without a gui?
An interesting alternative is krunvm. On my MacBook Pro M1 it takes less than a second to start a VM and get a Linux shell prompt with krunvm . When I boot up a Fedora CoreOS on the same computer it takes about 17 seconds. Note though that krunvm is for managing lightweight VMs created from OCI images.

Krunvm – Create MicroVMs from OCI Images
These specific microVMs are managed by: https://github.com/containers/libkrun#goals-and-non-goals (linked directly to project scopes).
In summary though (others redacted):
# Goals - Execute Docker Containers as QEMU MicroVMs

Show HN: krunvm – Create and run lightweight VMs from OCI images
The key is that libkrun (https://github.com/containers/libkrun), the library that krunvm uses for running the VMs, as recently integrated support for Hypervisor.framework on ARM64, in addition to KVM.
As for buildah, the Homebrew repo contains a build that includes this PR (https://github.com/containers/storage/pull/811).
