OK, thanks Damjan and Billy. It turns out that my problem was more fundamental. I have a bad vpp binary, as I built on an AMD processor, so the binary complains that the CPU does not have SSE4.2 extensions.
Unfortunately when I "sudo service vpp start" there are no messages on the screen, so I assumed things were AOK at that point. I have to either look in /var/log/messages.log or issue "vpp" directly on the command line to see the errors. I wonder if it is possible to have user friendly error messages appear directly on screen when issuing "sudo service vpp start". Also I'll have to troubleshoot to see if there is a workaround for the SSE4.2 issue, unless somebody knows about AMD Phenom ii processors. Burt ps, in the past I used to just build code on a laptop and never tried running it:-) On Sat, Feb 18, 2017 at 8:04 AM, Billy McFall <bmcf...@redhat.com> wrote: > I have been editing ../vpp/dpdk/Makefile, search for IGB_UIO and change > the n to a y. > > Billy > > On Sat, Feb 18, 2017 at 6:31 AM, Damjan Marion <dmarion.li...@gmail.com> > wrote: > >> >> On 18 Feb 2017, at 05:48, Burt Silverman <bur...@gmail.com> wrote: >> >> Hi, >> >> I am trying to follow the procedures on https://wiki.fd.io/view/VPP >> /Build,_install,_and_test_images and https://wiki.fd.io/view/VP >> P/How_To_Connect_A_PCI_Interface_To_VPP but I end up with no igb_uio >> module; so I cannot >> # modprobe igb_uio >> >> and that seems to correspond to >> >> - *vpp-dpdk-dkms* - DKMS based DPDK kernel module package (only on >> Debian/Ubuntu) >> >> >> from https://wiki.fd.io/view/VPP/Build,_install,_and_test_images >> >> so what is the workflow when using Centos?
