Many thanks for testing the alpha4! :-)

Please test the kernels.

Thanks,

Hi All,

I released the RC1 of kernel 5.8 for the X1000 and X5000 today. The issue with KVM-PR has been solved. :-)
I tested qemu with -enable-kvm with this result:
qemu-system-ppc:

Code: Select all

qemu-system-ppc -enable-kvm -cdrom lubuntu-16.04-desktop-powerpc.iso -boot d
works and boots with live iso
Image
there are errors, but I don't specified -machine and -vga ... but the VM works.

qemu-system-ppc64:

Code: Select all

qemu-system-ppc64 -enable-kvm -cdrom lubuntu-16.04-desktop-powerpc.iso -boot d
KVM: Failed to create TCE64 table for liobn 0x71000002
KVM: Failed to create TCE64 table for liobn 0x71000003
qemu-system-ppc64: Requested safe cache capability level not supported by kvm, try appending -machine cap-cfpc=broken
It not works with qemu-system-ppc64. Do you know why?

I tested "qemu-system-ppc64/kvm-pr" with Lubuntu 14.04 PPC32 as guest on a Fienix host with a 64-bit kernel and a 32-bit userland. Unfortunately Lubuntu 14.04 doesn't boot if I use "qemu-system-ppc64/kvm-pr". It boots with "qemu-system-ppc/kvm-pr" without any problems.

The same as me with DebianSid 64b kernel+64b userland.
