I Dan,
on my G5 i have Debian sid ppc64 and the kernel is my last build the 4.8
About the issue you are find with kvm. Did you test an old version of qemu? Did you try to force the cpu setting with mac99? example -cpu g4?
Ciao
Luigi

It doesn’t work for me at all:
crab@powermac-g5:~/Documents/Qemu$ uname -a
Linux powermac-g5 6.0.0-6-powerpc64 #1 SMP Debian 6.0.12-1 (2022-12-09) ppc64 GNU/Linux
crab@powermac-g5:~/Documents/Qemu$ lsmod | grep kvm
kvm_pr 110777 0
kvm 309830 1 kvm_pr
#!/bin/bash
qemu-system-ppc64 \
-boot c \
-M mac99,via=pmu \
-m 2048 \
--enable-kvm \
-drive file=/srv/Qemu/debian_64bit.qcow2,format=qcow2,media=disk \
-netdev user,id=mynet0,net=192.168.76.0/24,dhcpstart=192.168.76.10 \
-device sungem,netdev=mynet0 \
-monitor stdio
Result:
dmesg is flooded with:
#!/bin/bash
[22936.303544] Couldn't emulate instruction 0x00000000 (op 0 xop 0)
[22936.315006] kvmppc_exit_pr_progint: emulation at 100 failed (00000000)
Exactly as described here:
Can you let me know:
1./ what is your host OS and kernel version?
2./ what version of Qemu you are using? (I’m using the version in Debian ports).
3./ what arguments are you using to start your guest?
Does it also work in Libvirt?
