After installation of Cloudstack, you can navigate to Infrastructure > System VMs and see two system VMs running:

  • Secondary Storage VM
  • Console Proxy VM

In the detail view of these VMs (and also in all guest instance VMs which you create) there is a button View Console which opens a new browser window/tab. After a small delay, the content of the console of the running machine should be visible in this window/tab. The admin guide of the current release version 4.1.1 shows the location of the button.

To understand why you see messages related to a domain 'realhostip.com', please read Role of realhostip in CloudStack.

Diagnostic Steps

If your browser hangs with a message 'Connecting to kk-ll-mm-nn.realhostip.com' or you receive an error (usually a timeout) in the Console View, perform the following steps which were compiled from a mailing list thread.

Find out the Link Local IP Address of your Console Proxy

Infrastructure > System VMs > Console Proxy VM > Link Local IP Adddress

SSH into the Console Proxy VM

ssh -i /var/lib/cloudstack/management/.ssh/id_rsa -p 3922 169.254.2.xyz

Check whether the Cloudstack Agent is running
ps aux | grep -v grep | grep com.cloud.agent.AgentShell

the result should be such a process description:

Check connectivity to public IP of Console Proxy

On the console proxy, find out the public IP with ifconfig:

ifconfig eth2

          inet addr:10.193.17.198  Bcast:10.193.17.255  Mask:255.255.255.0

          RX bytes:2447827 (2.3 MiB)  TX bytes:2324955 (2.2 MiB)

From your machine, on which the browser is running where you click on the Console View button, try to access port 443 of that public IP:

telnet 10.193.17.198 443
Trying 10.193.17.198...
