Can you post the output of this from the host?

  cat /proc/cpuinfo | grep platform

If it reports "PowerNV" then things should be working, so the error
needs investigation.

If it reports "pSeries", then that's not a normally supported scenario
for running KVM (since your host is already running as virtualized
pSeries partition running on top of the pHyp hypervisor rather than
KVM). You *might* have KVM support via 'PR' mode as opposed to the normal
'HV' mode, but that's generally used to do nested virtualization on top
of a KVM HV guest. To do it on top of a pHyp guest partition is probably
not something that's been actively tested.

I'd assume you're using PowerNV host, but you mentioned "PowerVM"
earlier which is synonymous with pHyp, so it warrants confirming.

-enable-kvm should work as expected on Power machines that support
KVM.

You seem to be running the command as a normal user. KVM generally
requires a priviledged user.

Unless things are different with Ubuntu, I don't think KVM is enabled by
default. Try your command with -enable-kvm to be sure.

Yah, this is not right.

I think the command you need is actually:

  ppc64_cpu --smt=1

I don't know if this is the root cause, but I would not
expect things to work in general without SMT=1
