Here is my scenario

I have engine and 2 nodes  running on VMware workstation with 5 interfaces each  with these responsibilities

vmtraffic - 192.168.192.X
display  - 192.168.193.X
storage - 192.168.194.X
migration- 192.168.195.X
ovirtmanagement - 192.168.196.X

Logical networks have been set up as above and all the networks are reachable....the only network with a gateway is the vmtraffic

192.168.192.143 with gateway 192.168.192.2

when i go to the nodes via the terminal , it doesnt set the gateway and theirfore that node when you do ip route ,i get this

[root@node01 ~]# ip route
192.168.192.0/24 dev vmtraffic  proto kernel  scope link  src 192.168.192.143
192.168.193.0/24 dev ens37  proto kernel  scope link  src 192.168.193.143
192.168.194.0/24 dev ens34  proto kernel  scope link  src 192.168.194.143
192.168.195.0/24 dev ens35  proto kernel  scope link  src 192.168.195.143
192.168.196.0/24 dev ens36  proto kernel  scope link  src 192.168.196.143
[root@node01 ~]#

I know the solution is to insert a static route but isnt the interface with a gateway supposed to be default gateway for any traffic ?

and if i put the routes manually ,wont VDSM overwite it ,say if i upgrade.
