[Qemu-ppc] issue related to boot aix 7.1 when I try to use qemu ppc64

Hi to all

I try to use ( into VM debian 10 running into VMWARE virtualization environment ) qemu ppc64 version to simulate an AIX 7.1 TL04 OS

root@vkvm-acmm:/AIX# qemu-system-ppc64 -version

QEMU emulator version 3.1.0 (Debian 1:3.1+dfsg-8+deb10u2)

I run the following commands into my linux DEB but after few time i have to following issue ( trap interrupt kernel see to end .. ):

qemu-system-ppc64 -cpu POWER8 -machine pseries -m 4096 -serial stdio -drive file=disk.img,if=none,id=drive-virtio-disk0 -device virtio-scsi-pci,id=scsi -device scsi-hd,drive=drive-virtio-disk0 -cdrom aix.iso -prom-env "boot-command=dev / 0 0 s\" ibm,aix-diagnostics\" property boot cdrom:\ppc\chrp\bootfile.exe -s verbose" -net nic -net tap -display vnc=:1

W: /etc/qemu-ifup: no bridge for guest interface found
