Created attachment 1859974 [details]
1.yml

Description of problem:

When using AddConnection2 dbus method to create an OVS system interface connection, the `ovs-external-ids` setting is ignored.


Version-Release number of selected component (if applicable):
NetworkManager-1.36.0-0.3.el8.x86_64

How reproducible:
100%

Steps to Reproduce:
0. Default install of RHEL 8 with NetworkManager-ovs installed also.
1. git clone https://github.com/nmstate/nmstate.git
2. cd nmstate/rust
3. download attachment as 1.yml
4. sudo ip link add eth1 type veth peer name eth1peer
5. sudo ip link set eth1 up
6. sudo ip link set eth1peer up
7. sudo nmcli device set eth1 managed yes
8. cargo run set 1.yml

Actual results:

nmstate rust fail with verification error.

Expected results:

no failure.

Additional info:

The root cause of this is NetworkManager use ifcfg format for eth1 which does not support ovs external id:

This is the dbus monitor output:
