Hi Yan, looks like you need to do some network troubleshooting:
- Can the management host name resolve itself? - Once started does the cloudstack-management service keep running? - Do you get any errors in /var/log/cloudstack/management/management-server.log - Does netstat show the management server listening on port 8250? - From any external host can you telnet to port 8250 and get a handshake response?
