Hi,
I'm running a VM on Ubuntu 16.04 with VMXNET3.
I have managed to compile and successfully run DPDK (v17.11.0-rc0) and the sample apps. However, pktgen (v3.40) ran into a segfault without me doing anything yet. Everything seemed to be OK until the pktgen> prompt showed up. Here's the message.
$ sudo .app/x86_64-native-linuxapp-gcc/pktgen
Pktgen:/>

The same problem showed up whether I ran pktgen by the py script, invoked directly, supplied the basic EAL args, pktgen args or not.
GDB gave this
Pktgen:/>

Thanks.
