Hi,

i already opened a bug report in jira. https://issues.apache.org/jira/browse/CLOUDSTACK-9590

1. first of all i add the host from cs management
2. Management Host cloudstack-setup-agent  -m 192.168.85.25 -z 3 -p 3 -c 9 -g 6e6cff15-3183-3cca-9389-ed1a78f6236a
-a --pubNic=cloudbr2 --prvNic=cloudbr0 --guestNic=cloudbr1 --hypervisor=kvm
3. agent will be dead after add to the host
4. restart agent
6. agent reconnect to server and wait with alert

In cs manager I get the following error.
