Re: cloudstack 4.6 Unable to add the host
Hi, In global settings there is a 'host' setting that should contain the mgt server ip. The KVM agent should get this ip in agent.properties during setup. The agent will connect to this ip on tcp/8250. Be sure this port is open and reachable (test using with telnet). Also, from my experience you need to run java7 on both mgt and hypervisor. Finally, when adding be sure the agent state is stopped. It should then be added without problems. Your logs show a connection issue from agent to mgt server on port 8250. Please double check this is reachable.

Re: cloudstack 4.6 Unable to add the host
-BEGIN PGP SIGNED MESSAGE- Hash: SHA256 Hi lixq, I think this is a connection or dns problem. Do you checked the firewall and ensure you neither have a connection or dns problem between your nodes? Try to ping the nodes each other using their hostnames. Also check the hostname and on what ip it maps itself. e.g. ping cloudstack-a from itself should *NOT* show an ip starting with 127. like 127.0.1.1.

Crowdfounding Ansible CloudStack Modules
Hi First I like to apologize for a bit off-topic mail here, but I might be interesting for you and your customers. Ansible is an awesome tool, and I worked hard to integrate CloudStack support. Help me to complete my work for fully configuring a cloud just using ansible. More details can be found on http://renemoser.net/blog/2015/11/26/crowdfounding-ansible-cloudstack-modules/ (no need for reply, spread the word would be much appreciated) Thank you! Regards René
