The PHT_SERVER_INFO handle is a container that contains information about a host machine. The information includes the Virtuozzo Service port number, host name, OS version, product version, and host machine UUID. To obtain this information for the specified Virtuozzo Service, use the PrlSrv_GetServerInfo function. You can also search for Virtuozzo Services running on your network by executing the PrlSrv_LookupParallelsServers function. The function returns a list of PHT_SERVER_INFO handles for the Virtuozzo Services that it finds. The returned information can be used to establish a connection with the Virtuozzo Service of interest.
