What microVM means
A microVM is a lightweight virtual machine with its own dedicated Linux kernel, hardware-isolated by KVM. The minimal device model keeps cold boot in seconds, not minutes, with around five megabytes of per-VM overhead.
Firecracker is the microVM monitor we run. The device model includes only what a modern Linux guest needs: virtio block, virtio net, a serial console. No legacy PCI, no BIOS emulation. Smaller attack surface, faster boot, less memory per instance.
Container vs full VM vs microVM
| Feature | Container | Full VM (QEMU) | MicroVM (Firecracker) |
|---|---|---|---|
| Cold boot | Sub-second | Minutes | Under 3 seconds |
| Per-instance overhead | Megabytes | Hundreds of megabytes | ~5 MB |
| Isolation | Shared kernel | KVM, hardware | KVM, hardware |
| Dedicated kernel | No | Yes | Yes |
| Snapshot resume | Limited | Yes, slow | Yes, fast |
KVM hardware isolation, dedicated kernels, per-VM network namespaces. Included on every instance, no add-ons required.

Frequently Asked
A microVM is a virtual machine with the isolation guarantees of a full VM but the start-up time and overhead of a container. The hypervisor strips out legacy device emulation and ships only what a modern Linux guest needs, which is why cold-boot times measure in seconds rather than minutes.
