Krunvm – Create MicroVMs from OCI Images

• libkrun

  8 924 9.0 Rust

  A dynamic library providing Virtualization-based process isolation capabilities

  

  It runs on top of https://github.com/containers/libkrun. Similar to Firecracker but seems specifically targeted to making microVMs out of OCI containers (via CLI) as opposed to Firecracker which uses a downloaded kernel and rootfs and is managed via API ala https://github.com/firecracker-microvm/firecracker/blob/main....

  But I'm no expert, just by armchair take on things.

• kubevirt

  52 5,665 10.0 Go

  Kubernetes Virtualization API and runtime in order to define and manage virtual machines.

  

  If I'm understanding correctly, it's OCI compatible in the other direction - it consumes OCI compatible images, but it doesn't expose an OCI compatible layer on top for orchestration.

  kube-virt[1] is a thing, though, that provides k8s orchestration for VMs. I don't see why you couldn't use krunvm microvms with that

• crun

  31 3,080 9.4 C

  A fast and lightweight fully featured OCI runtime and C library for running containers

  

  It looks like crun already supports krun: https://github.com/containers/crun/blob/main/crun.1.md
