It looks like delay can only be non-negative, so "unsigned long" would work.
The only change that'd have to accompany it would be s/%ld/%lu/
in a printf format string.

How about using enum virNetworkForwardType?
Nicer for debugging.

This is never negative, so could be "unsigned int".

How about pid_t?
