Good morning all,
I'm rather new to this so please forgive my ignorance. I've searched official
Oracle documentation, the oVirt administration guide, reddit, LLMs, and about
every other source I could find but haven't seen anything that allows me set up
a bond successfully.
For background, I'm currently using one server as management and another server
as a local storage host. I'm not smart enough yet to do network storage.
I've tried to create a bond in two ways: the recommended way (in the
administration guide, Oracle documentation, etc.) of simply creating a bond
within OLVM by dragging/dropping interfaces to form a bond. Also, I've created
a bond manually on my management server and verified it was present in the
hosts -> network interfaces screen. When I attempt to assign a logical network
to the bond, I get some variation of the following in /var/log/vdsm/vdsm.log:
from=::ffff:10.90.104.68,37286, flow_id=6d139ffe-d9dc-4993-b050-72baa9eca527

After some research, it seemed like the solution was to take the "desired"
state and use nmstatectl apply filename.yaml to apply the desired state.
However, doing so produces the following in the same log:

I have no issues using a single interface. I drop the logical network (PLZ-NET)
onto the interface (e.g. eno2) and everything works swimmingly but bonding just
won't work.
If anyone has guidance or can point me to a solution, I would greatly
appreciate it. I've been banging my head against the wall for a week.
