OVS-based cluster adding vdsm report 'RTNETLINK answers: File exists' error in supervdsm.log in release 4.0.2
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?

Hi Mark, This and some other problems have been fixed on the master branch. I would suggest using the master branch for your tests, at least until the fixes are back-ported to the 4.0 branch. Thanks, Edy. On Wed, Aug 10, 2016 at 8:34 AM, lifuqiong <lifuqiong@cncloudsec.com> wrote:
