Comment 0 for bug 1656112

Upon running the virtualization test from the certification test suite, the kvm guest test fails with the following error:

kvm_init_vcpu failed: Invalid argument

This same test works on multiple other IBM Power 8 and Openpower servers. kvm-ok tells us that kvm virtualization is supported. I have tried with SMT enabled and disabled. I have tried the latest cloud image as well as previous onces we had saved. I have tried running the qemu-system-ppc64 command found below manually with the same error.

The full output from the test is as follows:
