Hi,
I'm a cloud computing R&D engineer. Use OVS as virtual switch, all virtual
machines and containers communicate with OVS.
I use OVS VLAN.
OpenvSwitch Version 2.3.1 (nothing change)
CentOS 6.6
In the process of I use, encounter the flowing problems.
Need your help!
1、ovs-vswitchd.log always report warnings:
2015-05-17T00:52:50.463Z|00575|timeval|WARN|Unreasonably long 2020ms poll

2、I also encounter this problem:
when I execute
ovs-ofctl dump-flows br-int
not always reponse, but ovs-vsctl show is OK!
Thanks!
