Hi Cédric,
i have the 4.11 rc1 . on fedora 25 ppc 64 on both machine Qoriq and on
G5 Quad.
On the 2.8 this issue isnt present but
I did the test o Qoriq e5500 a book3e processor and on 2.8 if i made:
qemu-system-ppc64 --enable-kvm the true result is:
qemu-system-ppc64: Unable to find CPU definition: host
on qemu 2.9 rc1
./qemu-system-ppc64 --enable-kvm i have :
qemu-system-ppc64: KVM and IRQ_XICS capability must be present for in-kernel
XICS
On Qoriq if i pass the -cpu e500 (normal thing) all is working right
qemu 2.9rc1 all boot and so and so.
On G5 the -cpu variable dont fix the issue.
I can build a new kernel release , usually mine dont have xics enabled
because G5 dont have that feature, if needed i can enable it for
testing.
Hope my english is understandable.
ciao
Luigi

I guess this is an issue with the host kernel. Which one are you running
?

Status in QEMU:

Bug description:
Hi,
i did many tests on qemu 2.8 on my BE machines and i found an issue that i
think was need to be reported
Test Machines BE 970MP
if i setup qemu with
qemu-system-ppc64 -M 1024 --display sdl(or gtk),gl=on --device virtio-
gpu-pci,virgl --enable-kvm and so and so
result is doubled window one is vga other is virtio-gpu-pci without
any start of the VM . pratically i dont have any output of openbios
and on the virtual serial output
the same issue i found is if i select:
qemu-system-ppc64 -M 1024 --display gtk(or sdl) --device virtio-gpu-pci
--enable-kvm and so and so
i had been try to change all the -M types of all kind of pseries without any
positive result.
Ciao
Luigi
