Fixed bug with _vm_action (updated).

        return self._server.list(query)

    def _vm_action(self, query, method, *args, **kwargs):

        vms = self._server.list(query, show=set(('vm', 'role')))

        hypervisors = list(self._server.iter_connected_role('hypervisor'))

        vms = self._server.list(query, show=set(('r', 'h')))

        hypervisors = list(self._server.iter_connected_role('hv'))

        for hv in hypervisors:

            vm_to_start = []

            for vm in vms:

                if vm['role'] != 'vm':

                    pass

                if vm['r'] != 'vm':

                    continue

                elif vm['id'].split('.')[0] == hv.login:

                    vm_to_start.append(vm['vm'])

                    vm_to_start.append(vm['h'])

            if vm_to_start:

                hv.connection.call(method, vm_to_start, *args, **kwargs)
