---------------------------------------------
Summary: KVM Agent setup fails due to cloudbr0 set as public
network interface
Key: CLOUDSTACK-316
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-316
Project: CloudStack
Issue Type: Bug
Components: KVM, Management Server
Affects Versions: 4.0.0
Environment: Ubuntu 12.04
CloudStack 4.0.0-incubator
Reporter: Wido den Hollander
I just set up a fresh CloudStack 4.0 platform and tried to add a host via the
wizard.
My Basic network settings:
- guest: vlanbr672
- private: vlanbr670
During the wizard there is never a prompt for the public network, you can only
set the storage label, but I didn't do that.
I kept waiting for the hypervisor to come online, but the agent wouldn't start.
The log showed:

This was due to this setting in agent.properties:
public.network.device=cloudbr0
My setup doesn't have cloudbr0, so why was this set?
The management server log shows me:

--guestNic=vlanbr672 output:CloudStack Agent setup is done!
As you can see, the management server came up with "cloudbr0" for the public
network, while I never configured that.
Should public network be set to guest network in a Basic KVM zone?
