 Krunkit runs super‑light VMs on macOS/ARM64 with a focus on GPU access. It builds on [libkrun](https://github.com/containers/libkrun), a library that embeds a VMM so apps can launch processes in a hardware‑isolated VM (HVF on macOS, KVM on Linux). The standout feature is GPU support in the guest via Mesa’s Venus Vulkan driver ([venus](https://docs.mesa3d.org/drivers/venus.html)), enabling Vulkan workloads inside the VM. See the project: [containers/krunkit](https://github.com/containers/krunkit).
