Hello! Wanted to see if anyone else has ran into this issue or if you can
point me in the right direction...
I have 2 KVM CloudStack-agents version 4.11.2 running Centos7 that are not able
to start the cloudstack-agent service if the agent.propreties file specifies
the variable "private.network.device=cloudbr0". This is automatically added to
the config file when the agent connects to the server, if the private network
is commented out the service is able to start up but any system VMs are unable
to connect to the network. This environment was working with my original 2 KVM
agents, but after deleting the hosts and rebuilding with identical network
config I've ran into this issue. I have logs and configs below, any ideas what
is wrong? This is a dev proof of concept environment, so I can rebuild if
needed. Thank you for your time!

This occurs on version 4.11.1 and 4.11.2, and I've seen other threads with this
issue on earlier versions that reported downgrading the agent fixed this issue.
