Subject Re: Network Bridge - error
Date Thu, 07 Mar 2019 09:36:00 GMT
Hi Larry,

Looks to me like your network configuration isn't consistent - your enp2s0 interface is still
NetworkManager controlled, whilst the bridge isn't:

Mar 07 10:05:07 localhost.localdomain NetworkManager[4025]: <info>  [1551924307.4967]
ifcfg-rh: Ignoring connection /etc/sysconfig/network-scripts/ifcfg-cloudbr0 (d4b789ba-7321-548d-dabd-5c4150da0266,"System
cloudbr0") due to NM_CONTROLLED=no.
. . .
Mar 07 10:05:07 localhost.localdomain NetworkManager[4025]: <info>  [1551924307.6674]
audit: op="connection-activate" uuid="740fc662-1d75-42ae-98ed-0ce92a0ca3dc" name="enp2s0"
pid=14783 uid=0 result="fail" reason="Can not find a master for enp2s0: Master connection
not found or invalid"
Mar 07 10:05:07 localhost.localdomain network[14650]: Bringing up interface enp2s0:  Error:
Connection activation failed: Can not find a master for enp2s0: Master connection not found
or invalid


I recommend you disable NM altogether - it causes nothing but problems. If you want a bit
more detailed network configuration overview check https://www.shapeblue.com/networking-kvm-for-cloudstack-2018-revisit-for-centos7-and-ubuntu-18-04/
