Two questions about creating a test for this code. How do I get the
actual args so I can compare them to my expected args to see what
isn't matching up? VIR_TEST_DEBUG=2 shows me what tests fail but not
any detail about why. I think it is because one of the parameters to
qemu is a file descriptor which could change for each run. Is there
some type of wildcard I can use like fd=%. I don't see any other tests
using file descriptors to compare to and am not finding anything in
any documentation I can find.

Thanks,
