However, the ping does. not work. (The details are attached to this email).
I think the issue is attaching the correct VM ports? Am I missing something?

First, make sure that ovs is installed correctly, e.g.
E.g. make sure something like this works
ovs-vsctl add-br MyBridge
if this is working, you would need the following three commands to create a
bridge and should in ovs-vsctl output
nmcli conn add type ovs-bridge conn.interface MyBridge
I have a bond, and running
ovs-appctl bond/list
bond type recircID slaves
MyBond active-backup 0 enp0s8, enp0s9
If I run:
nmcli connection modify ovs-slave-MyBond ovs-port.bond-mode balance-tcp
ovs-appctl bond/list
bond type recircID slaves
MyBond active-backup 0 enp0s8, enp0s9
nmcli conn
I am using following command to select LACP and active mode (for OVS bond),
nmcli conn add type ovs-port conn.interface MyBond master MyBridge
ovs-port.bond-mode balance-tcp ovs-port.lacp active
ovs-appctl bond/show
MyBond
bond_mode: balance-tcp
bond may use recirculation: yes,
.bond-mode ovs-port.lacpovs-port.vlan-mode
Also, I need to modify options, such as
active
passive
timeout
How can I modify these values after the bond is already created?
Thanks

Hello,
I am seeing two issues with NM and ovsdb. Issue # 2 is more critical.
In my configuration, I have two bridges in OVS. On one of the bridge, the
interface needs to be under Network Manager, so I have changed commands to:
nmcli conn add type ovs-bridge conn.interface
nmcli conn add type
Thanks, for the reply!
So I have to check manually? no way nmcli saying file exits and quit.
(because it will still make a file with name ifcfg-xxx-1 if ifcfg-xxx
exist).
