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

Hello Cédric,

with your last message you made me think about and make more test.

>The default machine for qemu-system-ppc64 is pseries.
yes usually with 2.8 i  boot  the VM without issue on G5 Quad  with the option  -M  pseries from 2.1 to 2.5 with kvm-pr enabled.
i did the tests and with all pseries now on 2.9 i have the same issue.
example:

qemu-system-ppc64 --enable-kvm -cpu 970fx_v2.0 -m 1024 -M pseries-2.1
qemu-system-ppc64: KVM and IRQ_XICS capability must be present for in-kernel XICS

but no issue if i run with -M mac99 before 2.9 was not possible use it on qemu-system-ppc64
It means it will no possible anymore in future release of qemu use open firmware on powermacs any moore?


>I admit the message is not very clear, but the host kernel is
>using a dev config.

Im so sorry, i learn English by my self reading ml and on irc chatting is too difficult where no one speak English  around.

>> On Qoriq if i pass the -cpu e500 (normal thing) all is working right qemu 2.9rc1
>> all boot and so and so.
>but you must be changing the machine right ?
not on Qoriq because it is book3e and is not so flexible like the G5 Quad who is book3s machine.
i can run qemu kvm only with emb hardware on Qoriq

>>On G5 the -cpu variable dont fix the issue.
>with which machine ?
On PowerMac G5 Quad 970MP it have similar hardware configuration of IBM intellistation power 285

I will do ASAP just the time to build it .

Thank you really much for your time and patience.
