Thank you for reply. Unfortunately that staff happens be in product environment with > 200Mb/s outgoing trafic from virtual machines (XCP 1.1 with upgrade to ovs1.4.3), so tcpdump is kinda impossible. Some data on configuration: no flow controller, some rules (antispoofing) are applied during

Re: [ovs-discuss] monitoring traffic VM using sflow

The sFlow reported utilization numbers should be accurate for the physical NICs. There is no well defined link capacity for a vNIC and so the utilization numbers are meaningless (I believe the Open vSwitch sFlow implementation reports a nominal 100Mbits/s capacity for vNICs). When examining v

Hmm. Yesterday I looked over all of the datapath commits since version 1.4.3 and didn't see any bugfixes, not applied to branch-1.4, that would account for this particular message. That means that this may be a problem that we aren't yet aware of. Unfortunately, this particular class of issue is

1. RTNETLINK answers: File exists. My suggestion was based on this thread: http://www.linuxquestions.org/questions/linux-networking-3/rtnetlink-answers-file-exists-542525/ So you are saying that in usual simplest setup this "error" doesn't exist? With ovs 1.7.1, CentOS6.3x64 - who approve or refute
