Subject: [PATCH] Fix error message "UnboundLocalError: local variable 'path'
 referenced before assignment" when running vm.

When the drive argument can't be parsed in _prepareVolumePath function, the self.log.info statement will report the error in the /var/log/vdsm/vdsm.log because the local variable 'path' isn't assigned. The patch adds the else statement to assign the local variable.
