The Programming Guide talks about the basic data loop for Java and Perl, retrieving updates and applying them incrementally. Since C# is most similar to Java and there are no actual C# docs, I've been assuming that the C# API should be like the Java one, but the stub assembly generated for C# seems to lack some of the objects mentioned (Change, VHandleList, etc). Is the data loop handled in the background by the C# stub, or has it not been generated correctly on my machine?

I need to find out the whether an ESX host is managed by a VC or not ? And I need to find out by querying ESX Host Web Service running on ESX Host by using an HOST SDK API. I do not want to go through via VC SDK Web Service. I tried to use HostSystem.QueryHostConnectionInfo()[/b] by calling on ESX Host Web Service connection, which returns HostConnectInfo, this object contains a member "serverIp" whose value as explained in VI SDK Reference guide:” The IP address of the VirtualCenter already managing this host, if any.", But this property shows as "Unset" when I queried on ESX Host Web Service connection. But the same HostSystem.QueryHostConnectionInfo() by calling on VC Web Service connection, returns this property as my VC IP address (serverIp=xx.xx.xx.xxx) And also even I tried to check HostRuntimeInfo. connectionState, but this is always returning “connected” on ESX, but returns “connected” / "disconnected” on VC based on the current state. So even this property from ESX Host Web Service is also not useful to find whether ESX is managed by the VC or not. Is there any one who knows any other reliable way to find whether ESX is managed by a VC or not by querying directly ESX web service ?

I'm using the vi perl toolkit to build a web application that allows users to connect to a VirtualCenter and interact with their Virtual Machines. They have to login at the beginning and a session is used to keep the connection to the VC. My question is: Is there a limit number of sessions that can be established to one VC? In this case it may be possible that 100 or more users are connected at the same time to one VC. Thanks, Benjamin

Hi, I'm getting this error from a call to VMGuestLib_UpdateInfo (error code 3). Guest SDK library is there of course and the session opens successfully. The error doesn't occur in other VMs on the same host. VMware Tools are installed in all the VMs on the host. The Guest API is not disabled in the VM's configuration file (no isolation.tools.guestlibGetInfo.disable = "TRUE" entry in it). I've run out of ideas. I'd appreciate any help or slightest suggestions.

I am trying to increase the size of an existing hard disk using the SDK and Java. I set up the file backing (VirtualDiskFlatVer2BackingInfo) and the virtual disk (VirtualDisk) with the same values as I used to create the hard disk initially. I then set the device and operation in the VirtualDeviceConfigSpec. The operation is set as "edit". The task completes successfully but the disk is not set to the size I requested. Setting the file operation causes an 'invalid operation' error from the VC. I have tried setting the DiskMode in the backing to both 'persistent' and 'append' but this does not seem to make a difference. Can anyone supply some guidance on this? (I am already signed up for the reconfigure webinar on Thursday)
