It is useful to have a separate
troubleshooting station to capture traffic or inject test packets
in the virtualized environment. It can be helpful to build a fresh
OS from scratch with common troubleshooting tools installed such
as tcpdump, nmap, hping, traceroute, iperf, tcpedit, netcat, etc.
This machine can then be powered down and converted to a template.
Each time the tools are needed, the troubleshooting client (virtual
machine) can be quickly deployed to the virtual switch(es) in question
and used to isolate networking problems. When the testing is complete,
the instance can simply be discarded and the template used again
the next time it is required.
