I forgot to mention the Monitor, if available. The "info status" would give you a lean status of the VM: either running or paused. I think the best way is QMP and, of course, the qemu-guest-agent running inside the VM. 2018-08-07 17:32 GMT+02:00 Vincenzo Romano : > Ping cannot

There is an overall benefit with virtio as it is more efficient on both the host and the guest. Then, during the installation, before the media selection and the actual partitioning you are given a chance to install extra drivers. That's the moment the drivers are needed. Il 04 gen 2017 02:12,
