libkrun is a dynamic library that lets programs run processes in partially isolated environments using KVM virtualization on Linux and HVF on macOS/ARM64. It embeds a lightweight VMM with minimal emulated devices behind a simple C API, enabling projects to add VM-based isolation without managing a full hypervisor.
Use cases
- add virtualization-based isolation to container runtimes like crun
- run GPU-enabled lightweight VMs on macOS
- launch microVMs with GPU acceleration for gaming
- run confidential workloads with AMD SEV or Intel TDX memory encryption
- embed lightweight VM isolation into an application via a C API
When to choose
- you need lightweight, fast-booting VM-based process isolation embedded in your own tool
- you want confidential computing support with SEV or TDX
- you need GPU-accelerated microVMs on Linux or macOS
When to avoid
- you need a general-purpose VMM with broad device emulation
- you need full compatibility with all workload types
- you require a stable 2.0 API before its first stable release
