You can add hosts under a datacenter object, folder object, or cluster object. If a host contains virtual machines, those virtual machines are added to the inventory together with the host. Information about configuring hosts is located in the vSphere Networking, vSphere Storage, vSphere Security, and vSphere Host Profiles documentation.


  • Open a vSphere Client session to a vCenter Server.
  • Verify that you have sufficient permissions to create a host object.
  • Verify that a Datacenter, folder, or cluster exists in the inventory.
  • Obtain the user name and password for an account with administrative privileges on the host.
  • Verify that hosts behind a firewall are able to communicate with the vCenter Server system and all other hosts through port 902 or other custom-configured port.
  • Verify that all NFS mounts on the host are active.


  1. Select Home > Inventory > Hosts and Clusters.
  2. Select a datacenter, cluster, or folder within a datacenter.
  3. Select File > New > Add Host.
