Hi,
Is there any way to for an instance to send any data to the compute node
( for my purpose a status byte is enough) ?
Generally, no, we don't want guests to be able to communicate with the
host via open channels. If you're looking for a way for a host to
respond to certain guest health/status conditions, you might want to
look at using a libvirt watchdog device. More information on this can be
found here:
