microvm

Supports eight hypervisors including QEMU, Firecracker, and cloud-hypervisor, allowing users to choose based on performance, features, or platform compatibility, as detailed in the hypervisor table.

Enables MicroVMs to be defined as NixOS configurations in a flake, leveraging Nix's reproducibility for consistent deployments, and can be run imperatively with the `microvm` command.

Uses read-only root disks with squashfs for smaller size or erofs for faster performance, and offers stateful storage via image volumes or shared directories through 9p/virtiofs.

Allows attachment of TAP interfaces or user networking, with vhost-net acceleration for high throughput (~10 Gbps with QEMU), supporting various network setups for isolation or performance.
