Re: [Qemu-ppc] [Qemu-devel] [Bug 1674925] Re: Qemu PPC64 kvm no display if --device virtio-gpu-pci is selected

[luigi burdo]

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 ?
