Oh, right, kvm_create_max_vcpus is a common test.  Can userspace detect that it's
running KVM-on-PowerVM (in a not completely unpleasant way)?  If so, an alternative
would be to keep the KVM_CAP_PPC_SMT change in v6 (patch 2) as a prep patch (before
adding PPC support to Makefile.kvm), and then add a
TEST_REQUIRE(!kvm_is_on_ppc_powervm()) or whatever.

I think I'd even prefer to take on an #ifdef (to scope it to PPC if necessary)
over open coding TEST_GEN_PROGS_COMMON.  LoongArch open coded its full test list
for some reason, and in less than a year it has started missing out on new common
tests.

What's wrong with VM types test?  That one really should Just Work on all
architectures.  It doesn't run on LoongArch, but I assume that's oversight?
