Sorry, that was premature. Apparently hugetable memory gets fragmented or leaks or something as the ovs-dpdk failed to start. Rebooting fixed that.
I still get many errors in the q-agt log file similar to this: ERROR neutron.agent.linux.utils [-] Command: ['ovs-ofctl', 'add-flows', 'br-int', '-'] Exit code: 1 Stdin: hard_timeout=0,idle_timeout=0,priority=0,table=0,cookie=0x0,actions=normal Stdout: Stderr: ovs-ofctl: br-int is not a bridge or a socket and ERROR neutron.agent.common.ovs_lib [req-ab1e1f65-d14c-4209-ac20-d29e450eda38 None None] Unable to execute ['ovs-ofctl', 'dump-flows', 'br-int', 'table=23']. Exception: Command: ['ovs-ofctl', 'dump-flows', 'br-int', 'table=23'] Exit code: 1 Stdin: Stdout: Stderr: ovs-ofctl: br-int is not a bridge or a socket But at least q-agt isn't dying. I remember why I hate fedora though.. Even though horizon says it is running and we turned the firewall to permissive, I can never access the website. Seems like something else is protecting or acting as a firewall. > -----Original Message----- > From: discuss [mailto:discuss-boun...@openvswitch.org] On Behalf Of Gabe > Black > Sent: Tuesday, August 25, 2015 2:06 PM > To: Mooney, Sean K; b...@openvswitch.org > Subject: Re: [ovs-discuss] duplicate option: of_interface > > Thanks for the reply and hints on changes...
