hi , The below error is because invalid coremask , your VM has only one core , but you are trying to assign eal option as -c 0xf that means you are assigning 1,2,3,4 cores to dpdk application which are not available in your VM . you can increase sufficient number of cores while u launch virtual machine .
please check EAL options for dpdk before proceeding . http://dpdk.org/doc/guides-16.04/testpmd_app_ug/run_app.html On Wed, Jun 29, 2016 at 2:20 PM, Raja Jayapal <raja.jayapal at tcs.com> wrote: > Hi All, > > I have installed dpdk(16.04) on ubuntu VM and trying to run > helloworld/testpmd application, but i am getting the below errors. > > root at host4-VirtualBox:/home/host4/dpdk/dpdk-16.04/examples/helloworld# > echo $RTE_SDK > /home/host4/dpdk/dpdk-16.04 > root at host4-VirtualBox:/home/host4/dpdk/dpdk-16.04/examples/helloworld# > echo $RTE_TARGET > x86_64-native-linuxapp-gcc > root at host4-VirtualBox:/home/host4/dpdk/dpdk-16.04/examples/helloworld# > ./build/helloworld -c f -n 4 > EAL: Detected lcore 0 as core 0 on socket 0 > EAL: Support maximum 128 logical core(s) by configuration. > EAL: Detected 1 lcore(s) > EAL: lcore 1 unavailable > EAL: invalid coremask > > Usage: ./build/helloworld [options] > > EAL common options: > -c COREMASK Hexadecimal bitmask of cores to run on > -l CORELIST List of cores to run on > The argument format is <c1>[-c2][,c3[-c4],...] > where c1, c2, etc are core indexes between 0 and 128 > --lcores COREMAP Map lcore set to physical cpu set > The argument format is > '<lcores[@cpus]>[<,lcores[@cpus]>...]' > lcores and cpus list are grouped by '(' and ')' > > root at host4-VirtualBox:/home/host4/dpdk/dpdk-16.04/app/test-pmd# ./testpmd > -c 0xf -n 4 -- -i --portmask=0x1 --nb-cores=2 > EAL: Detected lcore 0 as core 0 on socket 0 > EAL: Support maximum 128 logical core(s) by configuration. > EAL: Detected 1 lcore(s) > EAL: lcore 1 unavailable > EAL: invalid coremask > > Usage: ./testpmd [options] > > EAL common options: > -c COREMASK Hexadecimal bitmask of cores to run on > -l CORELIST List of cores to run on > The argument format is <c1>[-c2][,c3[-c4],...] > where c1, c2, etc are core indexes between 0 and 128 > > > I tried with the options provided in below thread, but getting same error. > http://openvswitch.org/pipermail/discuss/2014-December/016007.html > > Please let me know what could be the cause? > > Thanks, > Raja > > > -----Srinivasreddy R <srinivasreddy4390 at gmail.com> wrote: ----- > To: Raja Jayapal <raja.jayapal at tcs.com> > From: Srinivasreddy R <srinivasreddy4390 at gmail.com> > Date: 06/27/2016 07:03PM > Cc: "dev at dpdk.org" <dev at dpdk.org> > Subject: Re: [dpdk-dev] dpdk config on VM > > > hi, > check with the below link .With little changes you can make it work for > your use case . > > https://github.com/01org/dpdk-ovs/blob/development/docs/04_Sample_Configurations/02_Userspace-vHost.md > > > On Mon, Jun 27, 2016 at 2:50 PM, Raja Jayapal <raja.jayapal at tcs.com> > wrote: > >> Hi All, >> >> I am tyrying to install dpdk on ubuntu and test the applications. >> I have successfully installed dpdk on Host as per the instruction guide , >> but little bit confused on how to bind it with VM. >> >> VM1(TrafficGen)------Host(DPDK)------VM2(Receiver) >> >> Do we need to install ovs to test the flows for the above scenarios?. >> I did search a lot, but didnt get clear idea like how to do config on VM >> side. >> Please point out some config/installation guide for the same. >> >> >> Thanks in Advance, >> Raja >> =====-----=====-----===== >> Notice: The information contained in this e-mail >> message and/or attachments to it may contain >> confidential or privileged information.
