Reproducing on Yakkety-ppc64el first (to confirm it worked / or not
before 17.04):

# Create basic Guest
$ uvt-simplestreams-libvirt sync --source http://cloud-images.ubuntu.com/daily
arch=ppc64el label=daily release=xenial
$ uvt-kvm create --memory 2048 --cpu 4 --disk 16 --template
/home/ubuntu/ppc-template.xml --password=ubuntu "testguest" release=xenial
"arch=ppc64el" label=daily
# set current='2' in the guest
$ virsh edit testguest
# start the guest and test change
$ virsh start testguest
$ uvt-kvm ssh --insecure testguest "lscpu -e"
$ virsh setvcpus testguest 4 --live
$ uvt-kvm ssh --insecure testguest "lscpu -e"
Summary on ppc64el shows failing on Yakkety, Zesty
Cross Test on x86 shows it working on Xenial (sniff on later also ok)
So this seems not to be a regression.
Is it a feature request of some sort?
The request on parity?
There were no patches suggested as often on those bugs.
Is that a request for the inclusion of a change or the request to debug the
case?
