Right before freeze we got a security qemu update (which was auto
applied) on buildvm-ppc64le-01/02. Unfortunately this broke creating
images and since those two are our ppc64le image builder machines it's
not been fun.
I'd like to update them with qemu-2.11.2-3.fc28 which fixes the problem
commit (hopefully). If it doesn't it cannot make it worse, as they
always fail image building now anyhow.
has details and
has information on all the images
that haven't been building.
