[PATCH v8 8/8] parallels: implement VM creation

[Dmitry Guryanov <dguryanov@xxxxxxxxxxxxx>]

To create a new VM in PARALLELS we should issue "prlctl create" command,
and give path to the directory, where VM should be created. VM's
storage will be in that directory later. So in this first version
find out location of first VM's hard disk and create VM there.
