Hi,
I want to test ovs in vdsm of release 4.0.2. And according Petr's helpful advice,
created an ovs-based cluster and install vdsm to ovirt engine. But report a 'RTNETLINK
answers: File exists' error as bellows.
It seems that vdsm want to add a default gw through ' ip -4 route add default via
192.168.0.1' ; but of course this gateway already exists, why the vdsm will still add
the default gateway?
Error log:
