I don’t see this one.
Dang :(
What I see instead is failures on qemucapabilitiestest.
The tests seems to depend on a particular install path for the
qemu-system- binaries:
binary = g_strdup_printf("/usr/bin/qemu-system-%s",
data->archName);
On macOS, there is something called “system integrity protection”
which makes it a bit more difficult to add stuff to /usr/bin.
However, I don’t really think that’s the problem.
We definitely shouldn't be looking at the contents of the build
machine's actual /usr/bin directory in our test suite! That'd be a
bug in our mocking machinery.
I ran some tests with:
VIR_TEST_DEBUG=1
VIR_TEST_RANGE=1,3,5,7,9,11,13,15,17,19,21,23,25,27,29,31,33,35,37,39,41,43,45,47,49,51,53,55,57,59,61,63,65,67,69
/Users/ddd/Work/libvirt/build/tests/qemucapabilitiestest
The error I get seem to point to ‘hvf’ been unexected in the output:
15) 6.2.0 (x86_64) ...
In '/Users/ddd/Work/libvirt/tests/qemucapabilitiesdata/caps_6.2.0.x86_64.xml':
Offset 7557
Expect [c]
Actual [hvf'/>
<flag name=‘c]
I do not really understand what the test is supposed to do. It seems
to be comparing with reference files, but where does it get the
qemu capabilities to compare with from?
The test reads a .replies file from tests/qemucapabilitiesdata/,
parses it as if a QEMU binary had replied that way to our poking it,
figure out what the corresponding emulator capabilities are, format
them to XML and compare the result to the matching .xml file.
How should I proceed?
I've prepared patches that should address the issue you're seeing:
https://listman.redhat.com/archives/libvir-list/2022-August/233645.html
It'd be great if you could confirm that they work as intended.
