The regression testing done by comparison of command-line
generated from the network XML file and the expected
command-line arguments (read from file).
For the tests the pidfile should be set to NULL string, i.e.
(null) since no real invocation of the command is being done,
just the command-line is being generated and compared to the
expected one.

Should we be putting quotes around this? Or escaping the space, or
something?

You need to use virAsprintf instead of snprintf. You probably started
with qemuxml2argvtest.c, which has a similar function, and was changed
awhile back to eliminate large buffers on the stack.

This code to set abs_srcdir is no longer needed, as it's done in

requires a large stack buffer that triggers the same error as above).
