[ovirt-users] ovirt network setup hangs

[Bill James]

We recently upgraded our QA ovirt installation from ovirt3.6 to 4.0.3.
All seems to work fine except when I try to setup network configuration.

Even if I take an already configured host and change nothing when I 
select "Setup Host Networks" and press "ok" the window just hangs 
(spinning wheel) and task never finishes.
I can Delete the job and restart ovirt-engine and all is clean, till I 
try to setup a network, on any host, again.

I haven't found any log entries that seem to apply, but here's the start 
of the task:

2017-02-21 16:15:35,557 INFO 
[org.ovirt.engine.core.vdsbroker.vdsbroker.HostSetupNetworksVDSCommand]

', ipv4Gateway='null', ipv6BootProtocol='NONE', ipv6Address='null', 
ipv6Prefix='null', ipv6Gateway='null', swit
chType='LEGACY'},


Where would I look for more info?

Another error that is probably related is when I open Setup Host Network 
and click on the edit pencil I get an error: (ui.log)

Did I miss something in the upgrade?
