| # 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. |
