Hi Paul,
I am setting up Opencontrail (DPDK) on a physical host. Earlier system didn't support SSE4.2 so I had to change the compilation flag to SSE4.1 after which I was able to move ahead. Also I replicated the setup on another system which supports SSE4.2. Right now I am able to bring the contrail-vrouter-dpdk binary up and running with bond interface created successfully and am able to ping, through vhost, other hosts. Right now the problem I face is that vrouter-agent binary crashes. Although vRouter is stable.

Now when I start the contrail-dpdk binary, I get following error— contrail@contrail-23:~/dev/contrail-installer$ /usr/bin/contrail-vrouter-dpdk --no-daemon --socket-mem 1024,1024 ERROR: this system does not support “SSE4_2”. Please check that RTE_MACHINE is set correctly. After debugging the root-cause of above issue, I found that in file “third_party/dpdk/mk/machine/native/rte.vars.mk”, following check (marked in red) is missing. I came to this conclusion because— 1. On my setup, compiler doesn’t report SSE4_2 support a. checked with command “gcc -march=native -dM -E - < /dev/null | grep SSE4_2” 2. File “/var/run/dmesg.boot” is not present Based on above points and following code, “MACHINE_CFLAGS” will get set to “-march=corei7” # on FreeBSD systems, sometimes the correct cputype is not picked up. # To get everything to compile, we need SSE4.2 support, so check if that is # reported by compiler. If not, check if the CPU actually supports it, and if # so, set the compilation target to be a corei7, minimum target with SSE4.2 SSE42_SUPPORT=$(shell $(CC) -march=native -dM -E - < /dev/null | grep SSE4_2) ifeq ($(SSE42_SUPPORT),) CPU_SSE42_SUPPORT=$(shell if [ -f /var/run/dmesg.boot ] ; then grep SSE4\.2 /var/run/dmesg.boot ; fi) ifneq ($(CPU_SSE42_SUPPORT),) MACHINE_CFLAGS= -march=corei7 endif endif Ref: http://dpdk.org/ml/archives/dev/2014-July/004053.html<https://urldefense.proofpoint.com/v2/url?u=http-3A__dpdk.org_ml_archives_dev_2014-2DJuly_004053.html&d=DwMGaQ&c=LFYZ-o9_HUMeMTSQicvjIg&r=xtmPik_TP2fjPVGWP4yBRQ&m=aZEDgF0tlbar805wM4Q3Wv9REl7NtxOKgv3pc4OCP8o&s=qjrS29TkRD7cXDCmax9ogrKEVhswY9qaazFj8wui3S4&e=> So I added above additional code as highlighted in RED. Recompiled DPDK library as well as contrail-vrouter-dpdk binary and tried to run it.
