What type of system are you using?
Parts of that test are a little obscure-looking (you can probably blame
me for that). It starts with the sample config file and iterates
through it corrupting one line at a time. If running libvirtd with
each resulting corrupted config file does not yield the expected result,
its a failure.
A good place to start would be to save one of the failing config
files and to invoke libvirtd manually to see exactly what it's
printing and thus get a hint as to why the expected diagnostic is missing.

It'd be nice if "make check" would fail right away with an explanation
(overridable if you promise not to file bugs about resulting test failures ;-)
when libvirt has been built without certain essential-for-proper-testing
packages.
Or maybe a library analog of the existing bootstrap-time check for
minimal program version requirements:

autoconf 2.59
automake 1.9.6
autopoint -
gettext -
git 1.5.5

libtool -

To be honest this whole test is complete overkill for checking the config
file. The config file syntax allow 3 data types, integer, string and
array. There is no need for us to be running the libvirtd daemon, and
munging each possible setting in turn - we just need to test the edge
cases for the different data types. This test also completely misses
testing of the config file writing code, and things like escaping of
quotes, etc. I'd rather we just kill this test and write a better unit
test directly against the virConfPtr APIs in src/util/conf.c to validate
all the parser edge cases

On the contrary, I think it is useful to get test coverage of as much
of the code as possible, and especially of as many *failing* cases
as possible. Each of those failures goes through a slightly different
error path in the code. When I wrote it initially, it triggered a few
problems, and that's why I extended it to cover all of the cases.
Since then, the presence of that test has helped me avoid introducing
at least one bug, that would have been a double free.

Please don't remove it until there's a replacement with better coverage.

Yep, this one also fails for me. I don't think it is lack of a package, though
I could be wrong. It's probably worthwhile to dig into the test deeper and see
what is going on.

Thanks to migrating to a new machine, I've just had the opportunity to
confirm that installing cyrus-sasl-devel, then rerunning configure, was
sufficient to get past this failure. But the absence of
cyrus-sasl-devel did not stop building the rest of the package.
So now the trick is whether to skip this test if the prereq is not met,
or whether to make configure more insistent that the package exist.
Furthermore, configure barfed on me three separate times, before I got
to the point of reproducing this failure; each solved by installing more
packages:
libxml2-devel
gnutls-devel
device-mapper-devel
Again, it would be nice to have a configure patch that recognizes
failure for these mandatory packages with only one failed run, rather
than the current three separate configure runs to identify missing
prereqs one at a time.
