VDDK backup solution question ?

  Hi All,

I need to create simple utility for backup vmware virtual machines from ESXi server. I have installed ESXi server and create simple app on C++.

The first step I planned that VDDK correctly connects to my ESXi, but VDDK SDK couldn't connect and I couldn't continue investigate my solution solution.

this is example of log:

Log: VixDiskLib: Error occurred when obtaining NFC ticket for: XP Home. Error 4000 at 1450.

Error:   fa0 The virtual machine cannot be found

Is anybody could help me to connect ?

Base parameters: host port user pwd - I think those parameters are correct

VM_NAme ?

And very hard to explain: vmxSpec = "XP Home/XP Home-flat.vmdk?dcPath=ha-datacenter&dsName=datastore1";

Thanks for help.
