How to Modify the Properties of a VMware VirtualCenter Server
Applies To: Virtual Machine Manager 2008, Virtual Machine Manager 2008 R2, Virtual Machine Manager 2008 R2 SP1
To change the port used for connections to a VMware VirtualCenter server, update the administrative account used for the connections, or change the security mode for managing VMware ESX Server hosts, you can use the following procedure to modify the properties of the VirtualCenter server.
When you manage a VMware environment in secure mode, VMM authenticates each ESX Server host on all protocols used for communication. In secure mode, for hosts running ESX Server 3i, Secure Sockets Layer (SSL) over HTTPS (for ESX Server 3i) requires certificate authentication. For hosts running either ESX Server 3.5 or ESX Server 3.0.2, SFTP over Secure Shell (SSH) requires host public key authentication. Clear this option if you want to trust communications and require credentials only for the hosts.
For information about required credentials for ESX Server hosts and procedures for providing certificates and public keys, see Configuring Security for a Managed VMware Environment in VMM (http://go.microsoft.com/fwlink/?LinkId=145051).
