While I cannot disagree technically - would it be "useful" from a code
coverage viewpoint to have just "one" do the allowDiskFormatProbing
assignment similar to how various *TLS assignments are done in the
qemuxml2argvtest.c? With the appropriate comment regarding the security
implications of format testing. Doesn't matter which one - just choose
one and don't have the output file altered. Of course that'll be the
*one* test that everyone copies to create their xml2xml tests ;-)
Might be useful to note in the commit message that disabling resulted in
(I assume) default output of "<driver name='qemu' type='raw'/>" being
added to outputs for disks and "<format type='raw'/>" for mirrors... All
the input files that changed are just targets of links for output files.

Interesting that "format type='raw'" essentially appears twice...
Does this point out a bug in virDomainDiskDefFormat when printing
<mirror...> as formatStr is printed twice.
