Thanks kevin for helping us.
but i have got following error in changing value of C, even we can not give any value of C other than 1:
root at saloni-VirtualBox:/usr/src/dpdk-1.7.1/x86_64-native-linuxapp-gcc/build/app/test-pmd# ./testpmd -c 0xf -n4 -- -i --portmask=0x1 --nb-cores=2
EAL: Detected lcore 0 as core 0 on socket 0
EAL: Support maximum 64 logical core(s) by configuration.
EAL: Detected 1 lcore(s)
EAL: lcore 1 unavailable
EAL: invalid coremask
Usage: ./testpmd -c COREMASK -n NUM [-m NB] [-r NUM] [-b <domain:bus:devid.func>][--proc-type primary|secondary|auto]
EAL options:
-c COREMASK : A hexadecimal bitmask of cores to run on
-n NUM : Number of memory channels
-v : Display version information on startup
-d LIB.so : add driver (can be used multiple times)
-m MB : memory to allocate (see also --socket-mem)
-r NUM : force number of memory ranks (don't detect)
--xen-dom0 : support application running on Xen Domain0 without hugetlbfs
--syslog : set syslog facility
--socket-mem : memory to allocate on specific
sockets (use comma separated values)
--huge-dir : directory where hugetlbfs is mounted
--proc-type : type of this process
--file-prefix: prefix for hugepage filenames
Thanks

The core mask is set for 1 core with -c 0x1, but -–nb-cores=2 means that the app is to use 2 fwding cores. Try changing to –c 0xf
Thanks,
Kevin.

Hi Team,
We are running OVS with Intel DPDK Sample applications.
We have successfully run helloworld application as specified in Intel getting started guide.pdf
But We are getting some issues in running testpmd application as speified in (http://www.intel.in/content/dam/www/public/us/en/documents/guides/intel-dpdk-testpmd-application-user-guide.pdf).
We have used following command for it :
sudo ./testpmd -c 0x1 -n 4 -- -i --portmask=0x1 --nb-cores=2
EAL: Requesting 1238 pages of size 2MB from socket 0
EAL: TSC frequency is ~3178599 KHz
EAL: WARNING: cpu flags constant_tsc=yes nonstop_tsc=no -> using unreliable clock cycles !
EAL: Master core 0 is ready (tid=888ca800)
EAL: PCI device 0000:00:03.0 on NUMA socket -1
EAL: probe driver: 8086:100e rte_em_pmd
EAL: PCI memory mapped at 0x7fde88874000
PANIC in main():
Empty set of forwarding logical cores - check the core mask supplied in the command parameters
5: [./testpmd() [0x4240a5]]
4: [/lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xed) [0x7fde879fb76d]]
3: [./testpmd(main+0x4f2) [0x423df2]]
2: [./testpmd(__rte_panic+0xc1) [0x42379a]]

Can anyone please help me in resloving error?
Thanks
Hiteshi
