Hello Gianluca, Can you please check the ovn north db log. This is placed in /var/log/openvswitch/ovsdb-server-nb.log Please check if the logs has any new entries when you try to connect and when you issue the 'ovn-nbctl set-connection ptcp:6641' command. If the connection attempt is getting through, pvs db should print an error to the log.
Please also try restarting the ovn-northd service. Do the ovn-controllers connect to the south-db? You can verify this by looking at /var/log/openvswitch/ovn-controller.log on the ovn-controller host (please look for entries saying "... <north ip>:6642 connected") Marcin On Fri, Apr 21, 2017 at 1:09 PM, Gianluca Cecchi <gianluca.cec...@gmail.com> wrote: > On Thu, Apr 20, 2017 at 6:54 PM, Gianluca Cecchi < > gianluca.cec...@gmail.com> wrote: > >> Hello, >> I installed some months ago a test setup in 4.1.0 with ovn. >> Now after updating engine and host to 4.1.1 it seems the services are up >> but it doesn't work. >> If I run a VM with a network device in OVN external provider, it cant' >> boot and I get this in engine.log: >> >> >> [snip] > >> >> At the page >> https://www.ovirt.org/blog/2016/11/ovirt-provider-ovn/ >> >> I see this note about ports: >> >> " >> Since OVS 2.7, OVN central must be configured to listen to requests on >> appropriate ports: >> >> ovn-sbctl set-connection ptcp:6642 >> ovn-nbctl set-connection ptcp:6641 >> " >> >> and in my case I indeed passed from 2.6.90 to 2.7.0... >> >> Do I need to run these two commands? >> Or any other configuration settings? >> >> Thanks in advance, >> Gianluca >> > > I confirm that after running these two commands all work ok again and I'm > able to start a VM with a vnic provided by the OVN provider > > [root@ractorshe ~]# ovn-sbctl set-connection ptcp:6642 > [root@ractorshe ~]# ovn-nbctl set-connection ptcp:6641 > [root@ractorshe ~]# > > > _______________________________________________ > Users mailing list > Users@ovirt.org > http://lists.ovirt.org/mailman/listinfo/users > > -- MARCIN mIRECKI Red Hat <https://www.redhat.com> <https://red.ht/sig>
