509a4a40f9 cputest: Don't test cpuGuestData
The API is no longer used anywhere else since it was replaced by a much
saner work flow utilizing new APIs that work on virCPUDefPtr directly:
virCPUCompare, virCPUUpdate, and virCPUTranslate.

Not testing the new work flow caused some bugs to be hidden. This patch
reveals them, but doesn't attempt to fix them. To make sure all test
still pass after this patch, all affected test results are modified to
pretend the tests succeeded. All of the bugs will be fixed in the
following commits and the artificial modifications will be reverted.

The following is the list of bugs in the new CPU model work flow:

- a guest CPU with mode='custom' and missing <vendor/> gets the vendor
  copied from host's CPU (the vendor should only be copied to host-model
  CPUs):
    DO_TEST_UPDATE("x86", "host", "min", VIR_CPU_COMPARE_IDENTICAL)
    DO_TEST_UPDATE("x86", "host", "pentium3", VIR_CPU_COMPARE_IDENTICAL)
    DO_TEST_GUESTCPU("x86", "host-better", "pentium3", NULL, 0)

- when a guest CPU with mode='custom' needs to be translated into
  another model because the original model is not supported by a
  hypervisor, the result will have its vendor set to the vendor of the
  original CPU model as specified in cpu_map.xml even if the original
  guest CPU XML didn't contain <vendor/>:
    DO_TEST_GUESTCPU("x86", "host", "guest", model486, 0)
    DO_TEST_GUESTCPU("x86", "host", "guest", models, 0)
    DO_TEST_GUESTCPU("x86", "host-Haswell-noTSX", "Haswell-noTSX",
                     haswell, 0)

- legacy POWERx_v* model names are not recognized:
    DO_TEST_GUESTCPU("ppc64", "host", "guest-legacy", ppc_models, 0)

049df97504 tests: Re-enable ppc64 cpu tests
Now that all the changes have been implemented we can run the
test cases once again, after updating them to reflect the new
behaviour.

96b2c7459c cpu: CPU model names have to match on ppc64
Limitations of the POWER architecture mean that you can't run
eg. a POWER7 guest on a POWER8 host when using KVM. This applies
to all guests, not just those using VIR_CPU_MATCH_STRICT in the
CPU definition; in fact, exact and strict CPU matching are
basically the same on ppc64.

This means, of course, that hosts using different CPUs have to be
considered incompatible as well.

Change ppc64Compute(), called by cpuGuestData(), to reflect this
fact and update test cases accordingly.
