> 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:

> 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?
