tests: Avoid use of virQEMUDriverCreateXMLConf(NULL) We use the function to create a virDomainXMLOption object that is required for some functions. However, we don't pass the driver pointer to the object anywhere - rather than pass NULL. This causes trouble later when parsing a domain XML and calling post parse callbacks: Program received signal SIGSEGV, Segmentation fault. 0x000000000043fa3e in qemuDomainDefPostParse (def=0x7d36c0, caps=0x7caf10, opaque=0x0) at qemu/qemu_domain.c:1043 1043 qemuCaps = virQEMUCapsCacheLookup(driver->qemuCapsCache, def->emulator); (gdb) bt #0 0x000000000043fa3e in qemuDomainDefPostParse (def=0x7d36c0, caps=0x7caf10, opaque=0x0) at qemu/qemu_domain.c:1043 #1 0x00007ffff2928bf9 in virDomainDefPostParse (def=0x7d36c0, caps=0x7caf10, xmlopt=0x7c82c0) at conf/domain_conf.c:4269 #2 0x00007ffff294de04 in virDomainDefParseXML (xml=0x7da8c0, root=0x7dab80, ctxt=0x7da980, caps=0x7caf10, xmlopt=0x7c82c0, flags=0) at conf/domain_conf.c:16400 #3 0x00007ffff294e5b5 in virDomainDefParseNode (xml=0x7da8c0, root=0x7dab80, caps=0x7caf10, xmlopt=0x7c82c0, flags=0) at conf/domain_conf.c:16582 #4 0x00007ffff294e424 in virDomainDefParse (xmlStr=0x0, filename=0x7c7ef0 "/home/zippy/work/libvirt/libvirt.git/tests/securityselinuxlabeldata/disks.xml", caps=0x7caf10, xmlopt=0x7c82c0, flags=0) at conf/domain_conf.c:16529 #5 0x00007ffff294e4b2 in virDomainDefParseFile (filename=0x7c7ef0 "/home/zippy/work/libvirt/libvirt.git/tests/securityselinuxlabeldata/disks.xml", caps=0x7caf10, xmlopt=0x7c82c0, flags=0) at conf/domain_conf.c:16553 #6 0x00000000004303ca in testSELinuxLoadDef (testname=0x53c929 "disks") at securityselinuxlabeltest.c:192 #7 0x00000000004309e8 in testSELinuxLabeling (opaque=0x53c929) at securityselinuxlabeltest.c:313 #8 0x0000000000431207 in virtTestRun (title=0x53c92f "Labelling \"disks\"", body=0x430964 <testSELinuxLabeling>, data=0x53c929) at testutils.c:211 #9 0x0000000000430c5d in mymain () at securityselinuxlabeltest.c:373 #10 0x00000000004325c2 in virtTestMain (argc=1, argv=0x7fffffffd7e8, func=0x430b4a <mymain>) at testutils.c:863 #11 0x0000000000430deb in main (argc=1, argv=0x7fffffffd7e8) at securityselinuxlabeltest.c:381 Signed-off-by: Michal Privoznik <mprivozn@redhat.com>
