/**
 * VixDiskLibConnectParams - Connection setup parameters.
 *
 * vmxSpec is required for opening a virtual disk on a datastore through
 * the Virtual Center or ESX server.
 * vmxSpec is of the form:
 *    <vmxPathName>?dcPath=<dcpath>&dsName=<dsname>
 * where
 *    vmxPathName is the fullpath for the VMX file,
 *    dcpath is the inventory path of the datacenter and
 *    dsname is the datastore name.
 *
 * Inventory path for the datacenter can be read off the Virtual Center
 * client's inventory tree.
 *
 * Example VM spec:
 *    "MyVm/MyVm.vmx?dcPath=Path/to/MyDatacenter&dsName=storage1"
