routing policy problem in ovirt 4.4
Hello I created a cluster of ovirt 4.4 with 5 servers, I have a diferent gateway, ovirtmgmt and display network. In 4.4 routing is managed from network manager. Network manager seems to "forget" and recreate the route each time. So I cannot connect to the virtual machines console unless I run a ping for about a minute on the display network ip of the hypervisor, so network manager "wakes up" and "recreates" the route. I use this work around but it is not something that a user can do. What is the proper way to do this ? Thank you
Can you please share more details about the desired configuration and how you configured the network attachments on an example host? On Fri, Sep 18, 2020 at 11:43 AM <g.vasilopoulos@uoc.gr> wrote:

ok the desired configuration (which works perfectly on a similar cluster running ovirt 4.3) is as follows: 1 Gateway network 1 ovirtmgmt network 1 display network i.e. 10.0.0.0/24 is ovirtmgmt 10.0.1.0/24 is display network 193.92.xx.xxx/27 is gateway network So whenever I want to run an update on i.e. one host traffic reaches out through the gateway network packages get downloaded etc. Whenever a client wants to connect to a vm console he recieves the console.vv file which contains the host ip on the display network i.e. 10.0.1.111. Network attachments besides ovirtmgmt where configured through the engine. There is there is no routing at least for a "long" period of time between the client pc and the host display ip address on ovirt4.4. if I start pinging from the clients ip address and wait for a while then after I get a response I can connect to the console see bellow : [g.vasilopoulos@nireus ~]$ ping 10.252.83.27 PING 10.252.83.27 (10.xx.xx.xx) 56(84) bytes of data. 64 bytes from 10.xx.xx.xx: icmp_seq=40 ttl=62 time=0.292 ms 64 bytes from 10.xx.xx.xx: icmp_seq=41 ttl=62 time=0.354 ms 64 bytes from 10.xx.xx.xx: icmp_seq=42 ttl=62 time=0.317 ms for some reason there is a response after 40 seconds sometimes more... On ovirt 4.3 while setting up the network from the engine web-ui on the hypervisor the appropriate route-network_name and rule-network_name files were created. In 4.4 with network manager there are no such files, network manager is supposed to do this automatically, but for some reason there is no persistence on the route.. It seems it gets deleted. I do not know if this is the info you needed. In case you need further info, logs, etc please let me know.
Are you really sure it is a NetworkManager problem ? This sounds more like a switch MAC table gone wild. I would recommend you to get 'nmcli con show <connection>' & 'ip route' via a script during the situation is ongoing.
