Hi, The exception you got typically happens when a package is not installed on the host.
Did you install all the packages which appear in the System Requirements section of the DTS gsg ? (like python-xlwt, python-pexpect and the others) ? see: See: http://dpdk.org/doc/dts/gsg/sys_reqs.html In case this won't help, I would suggest to ask in the DTS mailing list, d...@dpdk.org.
