Peeling the onion in my series to update the QEMU capabilites replies: https://www.redhat.com/archives/libvir-list/2019-January/msg00793.html resulted in consideration of a possible alternative to how the SEV capability checking "works". As it turns out, the initial changes "massaged" the .replies output to add a "fake" reply on an Intel CPU for what amounts to AMD specific output. This naturally resulted in a "problem" when the next batch of a capabilites was created and there was no sev output, so an adjustment was made to limit what was tested to one capabilities version. Since there isn't separate Intel/AMD x86_64 output, the first patch in the series will alter the return for virQEMUCapsProbeQMPSEVCapabilities so that 0 would "change" into 1 for the mocked environment and allow the sev-guest bit to be set which allows QEMU_CAPS_SEV_GUEST to be set for any x86_64 arch environment. This only affects how qemuxml2argvtest handles generation of DO_TEST_CAPS_LATEST for launch-security-sev. The XML generated isn't modified, nor is the reply output data since that's separate. The key is the "0" return meaning a GenericError which is assumed to be returned when compiled-in support for SEV isn't there, but *could* be if the underlying hardware arch supported it. For the test purpose we have, that doesn't matter unless someone wants to go through the trouble of separating the caps*.replies files into "Intel" and "AMD" specific output. So yes a "workaround" of sorts, but nonetheless an alternative to the current static checking of what's been deemed incorrect reply data. The second somewhat unrelated patch is fallout of the review discussion about having a consistent process. I suspect it's a "starting point" from which we can evolve to create a consistent/repeatable process to create caps*.replies.
