I suspect that this may be related to the VSR register conversion. Can
you try applying all of the patches below on top of 4.0 to see if they
resolve the issue?

Title:
QEMU-SYSTEM-PPC64 Regression QEMU-4.0.0
Status in QEMU:
New
Bug description:
I have been using QEMU-SYSTEM-PPC64 v3.1.0 to run CentOS7 PPC emulated
system. It stopped working when I upgraded to QEMU-4.0.0 . I
downgraded back to QEMU-3.1.0 and it started working again. The
problem is that my CentOS7 image will not boot up udner QEMU-4.0.0,
but works fine under QEMU-3.1.0.
I have an QCOW2 image available at
https://www.mediafire.com/file/d8dda05ro85whn1/linux-
centos7-ppc64.qcow2/file . NOTE: It is 15GB. Kind of large.
I run it as follows:
qemu-system-ppc64 \
-name "CENTOS7-PPC64" \
-cpu POWER7 -machine pseries \
-m 4096 \
-netdev bridge,id=netbr0,br=br0 \
-device e1000,netdev=netbr0,mac=52:54:3c:13:21:33 \
-hda "./linux-centos7-ppc64.qcow2" \
-monitor stdio
HOST: I am using Manjaro Linux on an Intel i7 machine with the QEMU
packages installed via the package manager of the distribution.
