[ovirt-users] oVirt management network

[Bojan Popovic]

I have a hosted engine. It is on the same VLAN as the hosts are, so I am
not having connectivity issues. I am not going to alter that part of the
setup but I do need to add more networks, and I can not because I can
not save the configuration, no matter what I change it is not saved.

Ovirtmgmt is vlan-tagged.

Is there some config file that can be edited manually, or maybe it can
be done in the database?
