To install Ussuri, Packstack documentation[1] assumes Centos 8 or RHEL
8. However, it still wants me to disable NetworkManager. When I do that,
the Packstack loses all network configuration when rebooting, since
Centos 8 relies on NetworkManager to manage all aspects of networking.
Even after re-enabling NetworkManager and installing the NM OVS plugin,
br-ex remains down. Admittedly, I am quite clueless regarding the
management of OVS, with or without NetworkManager. Here are some of the
things I did (I also followed instructions for connecting Packstack to
the existing network[2]):
$ *cat /etc/sysconfig/network-scripts/ifcfg-br-ex*
NAME=br-ex
DEVICE=br-ex
DEVICETYPE=ovs
TYPE=OVSBridge
BOOTPROTO=static
IPADDR=172.24.4.1
PREFIX=24
ONBOOT=yes
$ *sudo nmcli d set br-ex managed yes*
$ *sudo ip l set br-ex up*
$ *nmcli d*
DEVICE TYPE STATE CONNECTION
ens3 ethernet connected ens3
br-ex openvswitch disconnected --
$ *sudo nmcli d connect br-ex*
Error: Failed to add/activate new connection: Device class
NMDeviceOvsInterface had no complete_connection method
$ *sudo journalctl -u NetworkManager | grep br-ex*

Any guidance?
