Comment # 1 on bug 1158111 from Chris Ward

What are the parameters for qemu-system-ppc64 to get it to run from the command
line the way that it runs under virt-manager ?

On my Tumbleweed system, I tried 'qemu-system-ppc64  -cdrom
ubuntu-19.10-server-ppc64el.iso -M pseries -cpu power9 -m size=1024 -hda
/var/lib/libvirt/images/ubuntu19.04-ppc64le.qcow2' ; this resulted in an
attempted installation with various 'illegal instruction' errors and the
install failed; but when I tried the install under virt-manager on a Leap 15.1
system, the install succeeded.

Then on my Tumbleweed system, I tried 'qemu-system-ppc64  -cdrom
ubuntu-18.04.3-server-ppc64el.iso -m size=1024 -M pseries -cpu power9 -hda
/var/lib/libvirt/images/ubuntu18.04-ppc64le.qcow2' ; this resulted in an
attempted installation with various segmentation violations and the install
failed; but when I tried the same command on a Leap 15.1 system, the install
succeeded.

So I'm not sure whether this is also a regression between qemu 3 and qemu 4, or
whether it's just that I have not got the parameters to qemu-system-ppc64
right.
