I am new to DPDK with Xen, but I am able to run DPDK applications without xen using hugepages. But when I try to do it in xen-dom0 it does not work. Let me explain: I have followed the intructions on the Getting Started Guide, so I execute the next steps: Dpdk/config/common_linuxapp CONFIG_RTE_LIBRTE_XEN_DOM0=y make config T=x86_64-native-linuxapp-gcc make install T=x86_64-native-linuxapp-gcc sudo modprobe uio sudo insmod x86_64-native-linuxapp-gcc/kmod/igb_uio.ko sudo insmod x86_64-native-linuxapp-gcc/kmod/rte_dom0_mm.ko rsv_memsize=2048 echo 2048 /sys/kernel/mm/dom0-mm/memsize-mB/memsize tools/dpdk_nic_bind.py --bind=igb_uio $(tools/dpdk_nic_bind.py --status | sed -rn 's,.* if=([^ ]*).*igb_uio *$,\1,p') The main problem appears when I try to execute helloworld for example. Sudo ./build/helloworld -c 0xf -n 2 ?xen-dom0 Output: EAL: Detected lcore 0 as core 0 on socket 0 EAL: Detected lcore 1 as core 0 on socket 0 EAL: Detected lcore 2 as core 1 on socket 0 ? EAL: Detected lcore 39 as core 12 on socket 0 EAL: Support maximum 64 logical core(s) by configuration. EAL: Detected 40 lcore(s) And it stops. If I execute dmegs I get the following: [ 1098.120193] helloworld[20116] trap invalid opcode ip:45adb7 sp:7fff4cf7e150 error:0 in helloworld[400000+115000] Here are the characteristics of the server: DPDK 1.7.1 xm info: host : vh05 release : 3.5.0-47-generic version : #71~precise1-Ubuntu SMP Wed Feb 19 22:02:52 UTC 2014 machine : x86_64 nr_cpus : 40 nr_nodes : 2 cores_per_socket : 10 threads_per_core : 2 cpu_mhz : 3000 hw_caps : bfebfbff:2c100800:00000000:00007f40:73bee3ff:00000000:00000001:00000281 virt_caps : hvm hvm_directio total_memory : 32722 free_memory : 28196 free_cpus : 0 xen_major : 4 xen_minor : 1 xen_extra : .5 xen_caps : xen-3.0-x86_64 xen-3.0-x86_32p hvm-3.0-x86_32 hvm-3.0-x86_32p hvm-3.0-x86_64 xen_scheduler : credit xen_pagesize : 4096 platform_params : virt_start=0xffff800000000000 xen_changeset : unavailable xen_commandline : placeholder dom0_mem=4096M max_loop=64 cc_compiler : gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) cc_compile_by : stefan.bader cc_compile_domain : canonical.com cc_compile_date : Wed Feb 19 15:32:59 UTC 2014 xend_config_format : 4 Thank you in anvanced.
