Pktgen failing in a virtualbox virtual machine

[cuyu tang <me@expoli.tech>]

I'm having segfault issues when running pktgen in a virtualbox virtual 
machine.

Here's what I run it in and some details about running the commands,

and what I can do to get it to run correctly


pktgen version: git main brunch
