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.
Working HV (centos 8.3 / vdsm 4.20.26.3-1) :
[root@drogo ~]# ip ru
