[ovirt-users] First oVirt engine deploy: missing gateway on hosts

Mon Sep 4 07:48:34 UTC 2017

Hi Mauro,

     yes, i do know this problem of gateway disappearing but i am not sure
why that happens because in my case it was happening on only on one server.
I used to add the gateway again on that node. I am just waiting for some
one to reply.

Thanks
kasturi
