--- Comment #4 from Jonathan Rivrain ---
I do not currently have access to workers on openqa.opensuse.org, but I could
reproduce this on a power8 machine on OSD, and If I emulate a power8 cpu on my
x86_64 laptop, it happens as well. I can provide /proc/cpuinfo from the host
where I reproduced it, but I can't do so from the guest, as it crashes right
away. Anyway, the qemu command line says "-cpu host" so I assume it's the same.
On openqa the VM is launched as follows
/usr/bin/qemu-system-ppc64 -device VGA,edid=on,xres=1024,yres=768 -g 1024x768
-only-migratable -chardev ringbuf,id=serial0,logfile=serial0,logappend=on

I could reproduce it with this simpler command :
