The first time you connect to a server using XenCenter, the Save and Restore Connection State dialog box appears. This enables you to set your preferences for storing your server connection information and automatically restoring server connections at the start of each XenCenter session; see Store Your Server Connection State.
XenCenter may be configured to display a warning message whenever a new or modified SSL (Secure Sockets Layer) security certificate is found when connecting to a managed server. Click View Certificate to view the security certificate. To prevent SSL certificate warnings from being generated, use the Security Settings tab in the XenCenter Options dialog box.
