As mentioned above, I have run the test multiple times with SMT both enabled and disabled. I get the same error. This is from running the test just now with SMT disabled:

WARNING: Image format was not specified for 'seed.iso' and probing guessed raw.
         Automatically detecting the format is dangerous for raw images, write operations on block 0 will be restricted.
         Specify the 'raw' format explicitly to remove the restrictions.
kvm_init_vcpu failed: Invalid argument

Also, KVM does in fact work with SMT enabled on ppc64el in PowerNV mode. KVM does not work with SMT enabled on a guest in PowerKVM mode. I have just run the test on the Power S822LC (8335-GTA Non-Virtualized) in PowerNV mode with SMT enabled and the guest booted fine.

That said, to limit variables, I will run the tests on the current server with SMT disabled for the duration of the troubleshooting.
