[dpdk-users] PCI device 0000:01:00.0 on NUMA socket -1 && !PANIC!: *** Did not find any ports to use ***

[Nishant Verma]

Hi Erfan,

It would be great if you let us know how you are planning to execute
helloworld and pktgen.
Because HelloWorld is a demo app just to show core functionality nothing
else, while pktgen can be used for all sorts of packet related operations.

One more thing, if you have allocated ports to one DPDK application then
you can't allocate those ports to any application. For example, if one
application is using one PCI then for another application that will be
blacklisted.

Thanks.
