crosvm is a secure, lightweight Virtual Machine Monitor (VMM) written in Rust, originally built for ChromeOS to run Linux and Android guests. It uses hardware-assisted virtualization (KVM, WHPX, etc.) with per-device sandboxed processes via Minijail, seccomp, and namespaces.
Use cases
- run Linux VMs on ChromeOS with Crostini
- run Android guests in a sandboxed VM
- run untrusted operating systems in an isolated environment
- emulate virtio devices like network, disk, GPU, and audio for guests
- test Android builds with the Cuttlefish emulator
- run lightweight VMs on Windows via WHPX or HAXM
When to choose
- you need a memory-safe, security-focused VMM written in Rust
- you want per-device process sandboxing with seccomp and namespaces
- you target ChromeOS, Android, or Linux with KVM-based virtualization
- you need broad virtio device support including GPU acceleration and vhost-user
When to avoid
- you need a full-featured general-purpose VMM with a GUI like VirtualBox or VMware
- you require macOS host support
- you need extensive non-virtio device emulation or live migration like QEMU offers
- you want a tool with a large third-party plugin ecosystem
