Odd that they'd all fail for you.
Only one fails for me: libvirtd-pool
and daemon-conf is mistakenly skipped due to use of ancient
automake-1.9.

As you know, that's because you're building with RHEL5's ancient
version of automake.
That is a no-no (for many reasons) but easy to work around.
IMHO, no one should never build using such old autotools,
but I do know how we're currently constrained. no choice.
That is not a no-no. It is fundamentally a requirement for libvirt
that is not going to change.

Once I worked around automake-1.9's lack of abs_top_builddir,
daemon-conf passed.
What error did you see?
I want to keep the diffs strict. While sometimes more work,
This has been a total PITA for the entire time this test has existed
constantly breaking whenever something appears on stdout for reasons
totally unrelated to the test case. It is just not maintainable as
it is.

Didn't fail for me.
Provide more detail (e.g., actual warnings) and I'll be happy
to find a solution we can both accept.

It's easy to avoid that difference.
With the following, it passes for me:
This is still missing the point - the test is overengineered &
unmaintainable. There is absolutely no need to run the daemon
or run the QEMU driver in order to test the XML generation.
This test should never have been committed since you didn't
even wait for review or comments before committing.
While I like the idea of your new print-xml option,
I don't want to decreasing coverage.
It is not decreasing the test coverage - it is focusing the test
case on the thing that is actually being tested - the XML generation
of the virsh command to produce a more reliable & maintainable
test case which doesn't randomly fail & need disabling based on
configure options.

NACK to removing this test.
When built without qemu, this test should simply be skipped.
Removing test coverage (no matter how much you dislike the
current form) should be done only as a last resort.
Just do what daemon-conf does:
That is not sufficient. Even if the QEMU driver is compiled into
libvirt you cannot expect that you will be able run the QEMU
driver. We fundamentally *DO NOT* run the real hypervisor drivers
in the test suite. This is what the "test:///default' driver was
written to do.
