Hello,
from my understanding it should be possible to provide an absolute minimalistic guest agent functionality by writing a 5-liner that fills some basic info into the virto serial device within the guest VM. At least from what I can read in the source at github or the docs:
https://github.com/oVirt/ovirt-guest-agent/tree/master/ovirt-guest-agent http://www.ovirt.org/images/2/20/Ovirt-guest-agent.pdf
Currently I'm interested to provide the most simple data: IP address & FQDN for our SLES 11 guests (no guest agent yet). I tried to understand what I must write into the serial device but there is no change in the VM overview panel. Different combinations did not provide any success.
Maybe someone can send the syntax for the two required echo commands. For populating those two columns just use an init script inside the VM that echoes the following data into the serial console. A sample for a host with two IPs and name host.test.com:
echo '{"__name__": "network-interfaces", "interfaces": [{"name": "en1", "inet": "1.2.3.4"}, {"name": "en2", "inet": "9.10.11.12"}]}' > /dev/virtio-ports/com.redhat.rhevm.vdsm echo '{"__name__": "fqdn", "fqdn": "host.test.com"}' > /dev/virtio-ports/com.redhat.rhevm.vdsm Yes, this indeed would work.
Markus
