[dpdk-users] DPDK Test Suite failing with PREREQ EXCEPTION Traceback

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, dts at dpdk.org.

Regards,
Rami Rosen

It would be helpful if anyone could guide me with the correct pointers to go over this issue and help me advance further.

Thanking in advance
