Re: [ANN] oVirt 4.3.7 First Release Candidate is now available for testing

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?

1. Ovirt1 has a team device controlled by NetworkManager , but in engine those interfaces are unused 2. I guess that when I recently 'reinstalled' the host from UI, the old teamports' ifcfg-<DEVICENAME> was moved to ifcfg-<DEVICENAME>-1 and the original file was left empty. 3. When the system rebooted, network.service rereads all ifcfg-* files and starts the team0 , but when NetworkManager reads the empty files - he alters the /etc/resolv.conf which leads to out-of-sync status.
Still, this is only theory and as ovirt3 has no team device (plain gluster arbiter) - I'm not sure how close is this one.

Hi Sandro,
I have just updated to latest release candidate (2 clusters in total - 1 AMD , 1 Intel). The only issue observed is that after patching every host's ovirtmgmt (I have another one that has none of the 4 roles which was OK) is out of sync and has to be synced before removing maintenance.
Still the system was accessible.
Can you guide me which log reports the out-of-sync in order to further investigate.
+Miguel Duarte de Mora Barroso , +Dominik Holler can you please help here?
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?

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?

What is your motivation to use a team device, instead a bond managed by oVirt?

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. Best Regards,Strahil Nikolov В понеделник, 4 ноември 2019 г., 10:12:47 ч.

What is your motivation to use a team device, instead a bond managed by oVirt? 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:
Hi Dominik and thanks for the quick reply. Purely the load balancing for LACP support and the low overhead. Since teamd is probably going to be the future I wanted to have oVirt using it. Furthermore, teamd is much more flexible to extend, add new interfaces, change priorities and you name it.
It would be great if teamd support was added in the upcoming oVirt releases. I've seen there is an RFE for the same question I asked here.
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? Best Regards,Strahil Nikolov
