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.
Thanks in advance.
Markus

The gap I am
attempting to close at the moment is the commands which
need elevated rights, like shutdown, reboot etc
On other systems there is polkit or usermode (aka consolehelper) however
in the SLES case I would have to use sudo.
This is all prepared, however now I have to apply some finishing
touches. I hope to get the package on my build.opensuse.org repository
within this week.
