Hi, > AndroidPipe is a communication channel between the guest system and > the emulator itself.

This is currently not possible using the > virtserialport which can only be opened once. vsock probably works better then: http://events.linuxfoundation.org/sites/events/files/slides/stefanha-kvm-forum-2015.pdf Also: for opengl you might want check out virtio-gpu (assuming you can build mesa for android). https://www.kraxel.org/slides/qemu-opengl/ cheers, Gerd -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
