'make check' has been failing on VPATH builds since commit
907a39e7. The tests already had magic for munging path names,
but were munging to the wrong location, thus working only on
an in-tree build.
* tests/securityselinuxlabeltest.c (testSELinuxMungePath): Munge
to correct path.
There are many aspects of the guest XML which result in the
SELinux driver applying file labelling. With the increasing
configuration options it is desirable to test this behaviour.
It is not possible to assume that the test suite has the
ability to set SELinux labels. Most filesystems though will
support extended attributes. Thus for the purpose of testing,
it is possible to extend the existing LD_PRELOAD hack to
override setfilecon() and getfilecon() to simply use the
'user.libvirt.selinux' attribute for the sake of testing.
