Hi list,
I'm using OVS 2.6.0 and DPDK 16.07 on CentOS 7.2, following the
instructions on ovs/INSTALL.DPDK.rst.
When I start ovs-vswitchd, it can't function properly.
I got warnings like "ovs|00014|timeval|WARN|Unreasonably long 6567ms poll
interval (232ms user, 5958ms system)" and many others. I searched on the
Internet, and found a similar situation which is fixed by upgrading kernel.
It seems that ovs-vswitchd hangs. So I also upgraded kernel, but it didn't
solve the problem.
The logs of DPDK seems strange. I'm using an Intel 82599 10Gb Ethernet
Adapter, and bind it to vfio-pci kernel module. I also mount hugepages. I
can't figure out why it goes wrong.
I'd appreciate any suggestions and help on this issue.
Here are logs of ovs:
