Since commit 'b66ca0220a' the 'tpm-emulator' tests in qemuxml2xmltest started to fail unless 'make check' is either executed as root or with an user with access to /etc/qemu/firmware file. This is the error that happens in a regular 'make check' run with an unprivileged user: ------ 546) QEMU XML-2-XML-inactive tpm-emulator ... 1315 In '/home/danielhb/kvm-project/libvirt/tests/qemuxml2xmloutdata/tpm-emulator.xml': 1316 Offset 909 1317 Expect [1.2] 1318 Actual [default] 1319 ...

Expected result code=0 but received code=4libvirt: error : cannot open directory '/home/danielhb/kvm-pr oject/libvirt/usr/etc/qemu/firmware': Permission denied 1327 FAILED ------ The reason is that commit b66ca0220a changed the domain validation to fetch the capabilities in qemuDomainDeviceDefValidate time, directly impacting existing tpm-emulator tests in qemuxml2xmltest.c that that since then will attempt to read the /etc/qemu/firmware file that wasn't being mocked. This patch fixes it by adding the mock paths for /etc/qemu/firmware in qemuxml2xmltest.c as well, using the virFileWrapper API like it is done in commit 5b9819eedc71.
