- 1. Linux virtual machines for running containers (typically on macOS) ● Automatic host filesystem sharing ● Automatic port forwarding ● Built-in integration for containerd (and Docker, Podman, Kubernetes, Apptainer, ...) 1 https://lima-vm.io/ $ brew install lima $ limactl start $ lima nerdctl run -p 80:80 nginx
- 2. How it works 2 ● Hypervisor Virtualization.framework (default) or QEMU ● Intel-on-ARM binary executor Rosetta 2 (Virtualization.framework) or QEMU-user ● Filesystem sharing virtiofs (Virtualization.framework), virtio-9p (QEMU), or reverse-sshfs
- 3. How it works 3 ● Network ○ user mode networking (default) ○ socket_vmnet (for direct access to the IP, etc. with sudo) ● Port forwarding Implemented by watching /proc/net/tcp, iptables, and Kubernetes services
- 4. Built-in templates 4 ● Distros almalinux, alpine, archlinux, centos-stream, debian, opensuse, oraclelinux, rocky, ubuntu, ... ● Container engines apptainer, docker, docker-rootful, podman, podman-rootful, ... ● Container orchestration faasd, k3s, k8s, nomad $ limactl start --name=default template://docker
- 5. v1.0 (November 2024) 5 ● Changed the default VM driver on macOS: QEMU → Virtualization.framework ● Support nested virtualization on Apple M3 ● Support UDP port forwarding ● Added `limactl tunnel`: let the host join the guest network (via SOCKS) ● Bumped up containerd and nerdctl to v2
- 6. Future ideas 6 ● Virtio-GPU Venus ● Menu-based text user interface ● UX improvement for composing multiple VMs ● Plugin system for supporting other VM drivers
