Glad you got it working.
Usually you'd have a regular interface such as "eth0" connected in that
bridge.

Thank you for the help Nux!
Your comment on the bridges put me on the right path. Everything was
indeed
configured correctly. BUT, as VMs were created the MAC address of
cloudbr0
changed. This explains why the host was mostly configured and then
dropped
off at the end.
My fix was to add a dummy interface to the cloudbr0 bridge with a low
MAC.
This keeps the bridge MAC stable throughout the setup and subsequent
operation. Maybe this is brute force but it got me over the hump.

Making sure that indeed all your bridges are in order, your agent can
connect to the management server (eg telnet to mgmt:8250) and starting
with a clean /etc/cloudstack/agent as well as libvirtd set to
listen_tcp=1 and listen_tls=0, try to add the host again and if it
fails
send us again DEBUG logs.
Also make sure iptables and selinux are off.
