** Description changed: - Upon running the virtualization test from the certification test suite, - the kvm guest test fails with the following error: + [Impact] + + * Some newer Power8 derivates fail to work correctly e.g. Power S822LC + (8335-GTB) + + * This is a toleration change (no exploitation) for those HW releases + following the SRU policy of "For Long Term Support releases we + regularly want to enable new hardware.

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: Executing KVM Test DEBUG:root:Starting KVM Test DEBUG:root:Cloud image location specified: http://10.1.10.2/cloud/xenial-server-cloudimg-ppc64el-disk1.img.
