By default, the web interface uses virtual thumbnails to represent hosts. Each thumbnail quadrant displays a basic piece of information about a host. Click on a host to see details about its virtual machines, SmartProxy settings, and properties.

Discovering Hosts

CloudForms Management Engine automatically adds hosts from discovered providers. However, you can also discover hosts directly if not using a provider. Discovering hosts is only supported for standalone VMware ESX servers.

  1. Navigate to Infrastructure -> Hosts.

  2. Click 1847.png Configuration, then click 2119.png Discover Hosts.

  3. Select the types of host to discover.

  4. Enter a Subnet Range of IP addresses starting with a From Address and ending with a To Address. The cursor automatically advances as you complete each octet.
