Sorry for being vague.
I am trying to run neutron in a container. A container runs neutron
and OVS in host mode. While starting up, neutron creates an internal
bridge using ovs-vsctl. Later, it tries to look it up using `ip link
show` which does not return a result, causing neutron to crash. I
noticed that if I attach to my container at this point and add an ovs
bridge manually, it show up in ovs-vsctl but not in `ip link show`. I
ran ovs on the host to check if this issue happens on the host. I do
not need to run ovs on the host. Here is whats happening:
mngmt2:/opt/ocs # ovs-vsctl show
96d8a92e-c8f2-469d-be8b-73b8d8ec5c20
Bridge br-int
fail_mode: secure
Port br-int
Interface br-int
type: internal
ovs_version: "2.3.90"
mngmt2:/opt/ocs # ip link show br-int
Device "br-int" does not exist.
mngmt2:/opt/ocs # ovs-vsctl add-br test1
mngmt2:/opt/ocs # ip link show test1
Device "test1" does not exist.
mngmt2:/opt/ocs # ovs-vsctl show

br-int has similar entries in that file.
