Betreff: Pseudo Guest Agent for unsupported VM distro=0A=
=0A=
Hello,=0A=
=0A=
from my understanding it should be possible to provide an absolute=0A=
minimalistic guest agent functionality by writing a 5-liner that fills so=
me =0A=
basic info into the virto serial device within the guest VM. At least
fro=
m =0A=
what I can read in the source at github or the docs:=0A=
=0A=
https://github.com/oVirt/ovirt-guest-agent/tree/master/ovirt-guest-agent=
=0A=
http://www.ovirt.org/images/2/20/Ovirt-guest-agent.pdf=0A=
=0A=
Currently I'm interested to provide the most simple data: IP address =0A=
& FQDN for our SLES 11 guests (no guest agent yet). I tried to understand=
=0A=
what I must write into the serial device but there is no change in
the VM=
=0A=
overview panel. Different combinations did not provide any success.
=0A=
=0A=
Maybe someone can send the syntax for the two required echo commands.=0A=
=0A=
For populating those two columns just use an init script inside the VM that=
=0A=
echoes the following data into the serial console. A sample for a host with=
two=0A=
IPs and name host.test.com:=0A=
=0A=
echo '{"__name__": "network-interfaces", "interfaces":
[{"name": "en1", "i=
net": "1.2.3.4"}, {"name": "en2", "inet":
"9.10.11.12"}]}' > /dev/virtio-po=
rts/com.redhat.rhevm.vdsm=0A=
echo '{"__name__": "fqdn", "fqdn":
"host.test.com"}' > /dev/virtio-ports/c=
om.redhat.rhevm.vdsm=0A=
