Alex, Interesting problem, these functions are sensitive because they happen in the context of an autotest test, but outside a virtualization sub-test. Probably the 'right' way to do this is starting with virt_test:virt_test class and make the calls to preprocess, postprocess_on_error, and postprocess more flexible. Perhaps they could be pulled in from test_module similar to run_func?
The other item you may consider is, if there are only specific parts of pre/post process you need to run on remote host. If so, maybe the easy answer is to have wrap them in a check for a new params key that makes them run remotely. As for tcpdump, how exactly is it not valid? If it's related to the 1-hour time, this is 'timeout' parameter which defaults to 3000 seconds. Just set it for your install test to something longer. Otherwise, I'm not sure I follow what you need it to do differently, please explain. Thanks.
