There are no keyboard and mouse emulated by CHV. You interact with the VM either by (serial) console or via SSH.\n\nAs CHV only supports virtio devices, Windows support requires an image setup with the respective drivers and thus, needs to be prepared e.g. via QEMU beforehand.\n\nI can add a note about the limitations of Windows support in the spec, as that may be surprising for the operator. It should probably be in some documentation about CHV support.\n\nSome information about CHV Windows support can be found here: https://github.com/cloud-hypervisor/cloud-hypervisor/blob/main/docs/windows.md\n\nAdding better Windows support would be more of a long-term goal. It is not our top priority currently as there are more urgent things to add e.g. live migration.","commit_id":"c3245147d34b962d34cd62514b284e6b66ff4ad1"}]}
