Hi,
i've just tried to update my sandboxing environmnent after long time without update (i know it's bad...) and i'm facing a problem with multiple gateway. This environment work with 6 hypervisors (centos 8) and one manager on dedicated server, all this baremetal have 2 interface in 2 différent network protected by firewall. All my hypervisords have 2 network for ovirt, one "ovirtmgmt" for management (only SSH and internal admin stuff), the other "ovir_prod" for console, migration, and default gateway.
I've 3 hypervisors non updated which i can ping /ssh / ... (according to iptables) on the two interface without problem. But the 3 hypervisors just updated are accessible only on the "ovirt_prod" interface. I'm looking inside ip route/ ip rules it seems to miss something. I always configured my HV by ovirt gui so i does not understand what going wrong.
This is ip route/ip rules of my hv, it's like missing ip rules on non working HV The "route-ovirt_prod" file that does not exist on old HV.

Hi, from the vdsm version it seems that the upgrade was from 4.2 to 4.4.7. Direct upgrade like that is not supported. There were a lot of changes 4.4 networking among other changes which might result in what you are experiencing. Please take a look at upgrade path from 4.2 to 4.4 in https://www.ovirt.org/documentation/upgrade_guide/index.html Thanks, Ales -- Ales Musil Software Engineer - RHV Network Red Hat EMEA <https://www.redhat.com> amusil@redhat.com IM: amusil <https://red.ht/sig>
