[ovirt-users] Host DNS

[Todd Punderson]

That seems to have fixed things up, now when I save after assigning
networks I don't revert back to the old entries. Not that I do that very
often, but I'd probably forget about it and be left wondering why my name
servers were messed up.

Thanks again for your help!
