Hi, all! I'm adding three test for CCA compatibility: domaincapstest, qemucapabilitiestest, and qemuxmlconftest. This is because SEV-SNP added these three tests. I have three questions regarding these tests: 1. How to add tests to qemuxmlconftest 2. How to create launch-security-cca.xml 3. About the file output with VIR_TEST_REGENERATE_OUTPUT=1 1. How to add tests to qemuxmlconftest Following the example of launch-security-sev-snp tests, I've done the following. Is this correct? (1) Placed the following three files in tests/qemuxmlconfdata: launch-security-cca.xml launch-security-cca.aarch64-latest.xml launch-security-cca.aarch64-latest.args (2) Added the test processing to qemuxmlconftest.c's mymain() function: DO_TEST_CAPS_ARCH_LATEST_FULL("launch-security-cca", "aarch64", ARG_QEMU_CAPS, QEMU_CAPS_CCA_GUEST, QEMU_CAPS_LAST); 2. How to create launch-security-cca.xml Do I need to handmade this from scratch or is there an automated method? 3. About the file output with VIR_TEST_REGENERATE_OUTPUT=1 I created launch-security-cca.aarch64-latest.* using the method described in doc/advanced-tests.rst. And, I created the test data for qemucapabilitiestest and domaincapstest using the method described in tests/qemucapabilitiesdata/README.rst. VIR_TEST_REGENERATE_OUTPUT=1 ./qemuxmlconftest VIR_TEST_REGENERATE_OUTPUT=1 ./domaincapstest VIR_TEST_REGENERATE_OUTPUT=1 ./qemucapabilitiestest Can I use the generated file for testing as is? Because doc/advanced-tests.rst says: "VERY CAREFULLY to ensure they are correct" I assume that automatically generated expected values are checked for accuracy. If correct, they are adopted; otherwise, investigation and remediation are undertaken. However, due to the lack of explicit documentation, we require confirmation. Also, it appears to be generating expected values based on the execution environment. Do we need to worry about variations in execution environments? For example, executing qemuxmlconftest detects the following comparison errors, such as with aarch64-virt-minimal.aarch64-latest, etc. Expect [sandbox on,obsolete=deny,elevateprivileges=deny,spawn=deny,resourcecontrol=deny \ -m] Actual [m] Best Regards.
