Hello,
passing from old manual to current OVN in 4.3.1 it seems I have some problems with OVN
now.
I cannot assign network on OVN to VM (powered on or off doesn't change).
When I add//edit a vnic, they are not on the possible choices
Environment composed by three hosts and one engine (external on vSphere).
The mgmt network during time has been configured on network named ovirtmgmntZ2Z3
On engine it seems there are 2 switches for every defined ovn network (ovn192 and
ovn172)
Below some output of commands in case any inconsistency has remained and I can purge it.
Thanks in advance.
I'm very confused here; you mention that on engine there are 2
switches for every ovn network, but, on your ovn-nbctl list
logical_switch output I can clearly see the 2 logical switches where
the OVN logical networks are stored. Who created those ?
Could you show us the properties of those 2 networks ? (e.g. ovn-nbctl
list logical_switch 32367d8a-460f-4447-b35a-abe9ea5187e0 & ovn-nbctl
list logical_switch 64c4c17f-cd67-4e29-939e-2b952495159f)
+Marcin Mirecki does this ring a bell? AFAIU, the ovn network names
had to be unique - until bug [0] was fixed, where the network names
would have a whole different format - e.g.
ovirt-<network_name>-<generated_uuid> .
@Gianluca Cecchi , I notice that one of your duplicate networks -
'ovn192' - has no ports attached. That makes it the perfect candidate
to be deleted, and see if it becomes 'listable' on engine. That would
help rule out the 'duplicate name' theory.
At the moment, I can't think of a better alternative. Let's see if
Marcin comes up with a better test / idea / alternative.
Also, please let us know the version of the ovirt-provider-ovn,
openvswitch-ovn-central, and openvswitch-ovn-host.
