Hi, Is there any recommended way to exchange datas (i.e 128 bytes every 20 seconds) between an instance and its compute node ? On RHEV infra, I'm using a channel device ; it seems quite impossible to use the same way on OpenStack. (I didn't find a way to create the virtio controller and the channel device before launching the instance) Thx for help.
