Hi Dominik,
I think I found it - it seems that for some reason my gateway is missing in 'ip
route'.
Running 'ifdown ovirtmgmt; ifup ovirtmgmt' fixes it, which proves that network
scripts read properly the ifcfg-ovirtmgmt file.
Do you have any idea where to look for?
Best Regards,

Still, this is only theory and as ovirt3 has no team device (plain gluster arbiter) -
I'm not sure how close is this one.

Does this refers to the host ovirt3 without the team interface?
Maybe there is any other interface than ovirtmgmt which influences the
default gw? Is there an indication in any other ifcfg file or is a
connection managed by networkmanager?

Are you able to share the vdsm.log and engine.log after the ovirtmgmt?

It's releated to all 3 nodes.I've created a vdsm hook in
'after_ifcfg_write' that sets a 'DELAY=5' and 'STP=on' and after
reboot everything is OK.
I have just completely powered off the lab and after powering on - the gateway is OK, so
it cannot be reproduced any longer.

Do you remember if there was a hint shown as a tooltip if you hover the
mouse pointer over ovirtmgmt in
"Compute > Hosts > xxx > Network Interfaces > Setup Host Networks"
?
Are you able to share the vdsm.log and engine.log after the ovirtmgmt?

This was already discussed in 'Is teamd supported on 4.3' in which
you were already involved. I can't say it better -so I will quote:

Thanks Valentin for your nice explanation.
Would you comment this on the RFE
Bug 1351510 - [RFE] Support using Team devices instead of bond devices
or may I copy your text there?
