[ovirt-users] hosted-engine network

The set-shared-config does not allow editing of the vm.conf or the ovf.

The original vm.conf that the hosted engine vm was started with contains
the correct network, so it must have been removed at a later stage.

To get a working environment I don't see another option then fixing the
network in the db.
What do the following queries return:
  1. select vm_interface.vm_guid, vnic_profile_id from vm_interface,
vm_static where vm_name='HostedEngine';
  2. select id from vnic_profiles where name='ovirtmgmt';
The vnic profile id that is returned from the first query should be the
same as the one that has the ovirtmgmt name in the second query.

Thanks,
Jenny
