# Hypervisor Support

|
|
|
Multiple hypervisor backends are supported. See
|
|
|
|
|
[Advanced Usage](running_crosvm/advanced_usage.md#hypervisor) 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 is crosvm's preferred hypervisor for Linux.

## Android Specific

|
|
|
|
|
|
|
The hypervisors in this section are used as backends of the
|
|
|
|
|
[Android Virtualization Framework](https://source.android.com/docs/core/virtualization).
