OCI MicroVMs for Proxmox VE

In plain words

OCI MicroVMs for Proxmox VE is a tool that integrates Oracle Cloud Infrastructure virtual machines with Proxmox VE, an open-source virtualization platform. It enables users to manage and deploy lightweight microVMs within their Proxmox environments, leveraging OCI infrastructure. The integration streamlines VM provisioning and management for organizations seeking to combine Proxmox's capabilities with OCI's cloud resources. This is designed for infrastructure administrators and DevOps teams working with virtualized environments.

From the sources

A Debian package that adds QEMU microvm machine type support to Proxmox VE. Runs OCI container images, Firecracker rootfs images , unikernels, and alternative OS as lightweight hardware-isolated VMs. ⚠️ Highly experimental. This project patches qemu-server internals and has not been tested in production. Use at your own risk. The patches are fully reversible — uninstalling the package restores the original files. We needed something between LXC containers and full QEMU VMs for running coding agents and other semi-trusted workloads. Hardware-isolated VMs with container-like speed , managed through the same Proxmox tools you already use. No new runtime — QEMU's microvm machine type is already…from github.com

  Sub-millisecond VM sandboxes using CoW memory forkingMar 2026 · github.com · ▲311

  I wanted to see how fast an isolated code sandbox could start if I never had to boot a fresh VM. So instead of launching a new microVM per execution, I boot Firecracker once with Python and numpy already loaded, then snapshot the full VM state. Every execution after that creates a new KVM VM backed by a `MAP_PRIVATE` mapping of the snapshot memory, so Linux gives me copy-on-write pages automatically. That means each sandbox starts from an already-running Python process inside a real VM, runs the code, and exits. These are real KVM VMs, not containers: separate guest kernel, separate guest…

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
