Re: [ovs-discuss] Why testpmd fails to start in VM while l2fwd works in the same VM?

Hi Mauricio, The issue is resolved by adding "--txqflags=0xf00 --disable-hw-vlan", that is, sudo -E ./testpmd -c 0x3 -n 2 -- -i --txqflags=0xf00 --disable-hw-vlan --portmask=0x3 --nb-cores=1 Thanks, Charlie On Fri, Aug 26, 2016 at 9:38 AM, Charlie Li <charlie...@gmail.com>

Re: [ovs-discuss] Why all of the packets are dropped at the dpdkvhostuser port?

Hi Mauricio, After applying the patch, the packets are flowing to the VM now. However, even at lower bandwidth, it always has a small percentage of frame loss. Is this expected behavior? Thanks, Charlie On Fri, Aug 5, 2016 at 9:22 AM, Charlie Li <charlie...@gmail.com> wrote: &g

[ovs-discuss] Why all of the packets are dropped at the dpdkvhostuser port?

Hi All, I set up a bridge with 2 dpdk ports and 2 dpdkvhostuser ports. And 4 flows are configured as the follows PHY0 -> dpdk port0 -> dpdkvhostuser port0 -> VM eth-ens3 PHY0 <- dpdk port0 <- dpdkvhostuser port0 <- VM eth-ens3

Re: [ovs-discuss] [ovs-dev] Compiler warnings with gcc 6.1 (On Fedora 24)

I have seen similar compiler error/warnings when compiling DPDK with Fedora 24. I tried to fix the warnings in the source code and passed the compilation, but still could not make the packet flow. Eventually I went back to Fedora 23. Thanks, Charlie On Tue, Jul 26, 2016 at 7:44 AM, Numan

Re: [ovs-discuss] Bug in Openvswitch 2.5

Hi Bala, I have a similar problem if I don't build DPDK and OVS every time after reboot. My workaround is to build DPDK and OVS again every time after a system reboot. # Build DPDK cd $DPDK_DIR make install T=x86_64-native-linuxapp-gcc # Configure & build OVS cd $OVS_DIR ./boot.sh ./configure

Hello, By now I am successful in running openvswitch-2.5.0 with DPDK-2.2.0 by following "INSTALL.DPDK.md ". I understand that I have to build DPDK and OVS for the very first time. # Build DPDK cd $DPDK_DIR make install T=x86_64-native-linuxapp-gcc # Configure & build
