A bit late, but here's an example of a complete command:
./vix-disklib-sample -clone virtdisk.vmdk -host esx3i -user root -password secret vmfsdisk.vmdk
Under the hood it looks like this:
VixDiskLibCreateParams createParams;
createParams.adapterType = appGlobals.adapterType;
createParams.capacity = appGlobals.mbSize * 2048;
createParams.diskType = VIXDISKLIB_DISK_MONOLITHIC_SPARSE;
createParams.hwVersion = VIXDISKLIB_HWVERSION_WORKSTATION_5;
vixError = VixDiskLib_Clone(targetConnection, targetDiskPath, srcConnection, srcDiskPath,
&createParams, // disk creation params, this parameter is ignored when connecting to a remote host
CloneProgressFunc, // function to watch progress with
NULL, // client data, typically null
TRUE); // overwrite if target exists
The VixDiskLib_Clone functions creates an additional connection which can be a source of problems. Several people have reported the example itself not working with some versions of VDDK 🙂
