Hypervisor Support

Multiple hypervisor backends are supported. See Advanced Usage for overriding the default backend.

Hypervisors added to crosvm must meet the following requirements:

Hypervisor code must be buildable in crosvm upstream.
- Within reason, crosvm maintainers will ensure the hypervisor's code continues to build.
Hypervisors are not required to be tested upstream.
- We can't require testing upstream because some hypervisors require specialized hardware.
- When not tested upstream, the hypervisor‘s maintainers are expected to test it downstream. If a change to crosvm breaks something downstream, then the hypervisor’s maintainers are expected to supply the fix and can't expect a revert of the culprit change to be accepted upstream.

KVM

KVM is crosvm's preferred hypervisor for Linux.

The hypervisors in this section are used as backends of the Android Virtualization Framework.
