Hi Cedric, 
Thanks for replying.
I think I want to go down the PowerNV Power 9
Which I will need the OpenPower firmware. 
Looks like the webpage for downloading prebuild witherspoon and skiboot is = down/dead. Hasn't been working for me for 24hours anyway
Is that the only place to download that firmware?

For baremetal emulation, please use the PowerNV machine. See this page :
  https://qemu.readthedocs.io/en/latest/system/ppc/powernv.html

HW is not fully emulated but QEMU has enough support to start a multichip system running any distro.

AIX only runs under the pseries machine (virtualized) and not on baremetal.=

This is a pseries machine (virtualized) and not baremetal.

Which machine do you want to run ? pseries is the VM platform as run by KVM= ,
It can run under TCG also. PowerNV is the baremetal platform on which KVM runs using the OPAL firmware. QEMU only has a PowerNV emulator, so TCG.

These are two very different PPC machines.

because you don't have any :) Add a device and link it to the netdev.


That's how I run a TCG pseries POWER9 machine on my x86 laptop:

qemu-system-ppc64 -M pseries,cap-cfpc=3Dworkaround,cap-sbbc=3Dworkaround,ca= p-ibs=3Dworkaround,cap-ccf-assist=3Don,ic-mode=3Ddual -m 4G -accel tcg,thre= ad=3Dmulti -cpu POWER9 -smp 4,cores=3D4,maxcpus=3D8,threads=3D1 -device vir= tio-net-pci,netdev=3Dnet0,mac=3DC0:FF:EE:00:00:02,bus=3Dpci.0,addr=3D0x2 -netdev tap,id=3Dnet0,helper=3D/usr/libexec/qemu-bridge-helper,br=3Dvirbr0= ,vhost=3Don -device virtio-scsi-pci,id=3Dscsi0,bus=3Dpci.0,addr=3D0x1 -driv= e file=3D./ubuntu-ppc64le.qcow2,if=3Dnone,id=3Ddrive-scsi0-0-0-0,format=3Dq= cow2,cache=3Dnone -device scsi-hd,bus=3Dscsi0.0,channel=3D0,scsi-id=3D0,lun= =3D0,drive=3Ddrive-scsi0-0-0-0,id=3Dscsi0-0-0-0,bootindex=3D1 -device qemu-xhci,id=3Dusb,bus=3Dpci.0,addr=3D0x4 -nographic -nodefaults -= serial mon:stdio

and a PowerNV POWER9 machine :

qemu-system-ppc64 -m 4G -machine powernv9 -smp 2 -accel tcg,thread=3Dmulti = -kernel ./open-power/images/witherspoon-latest/zImage.epapr -initrd ./open-= power/images/witherspoon-latest/rootfs.cpio.xz -bios ./open-power/images/wi= therspoon-latest/skiboot.lid -device pcie-pci-bridge,id=3Dbridge1,bus=3Dpcie.1,addr=3D0x0 -device ich9-ahci,id= =3Dsata0,bus=3Dpcie.0,addr=3D0x0 -drive file=3D./ubuntu-ppc64le-powernv.qco= w2,if=3Dnone,id=3Ddrive0,format=3Dqcow2,cache=3Dnone -device ide-hd,bus=3Ds= ata0.0,unit=3D0,drive=3Ddrive0,id=3Dide,bootindex=3D1 -device e1000e,netdev= =3Dnet0,mac=3DC0:FF:EE:00:01:03,bus=3Dbridge1,addr=3D0x3 -netdev bridge,helper=3D/usr/libexec/qemu-bridge-helper,br=3Dvirbr0,id=3Dn= et0 -device nec-usb-xhci,bus=3Dbridge1,addr=3D0x2 -device usb-storage,drive= =3Dusbkey -drive file=3D./usb.img,if=3Dnone,id=3Dusbkey,format=3Draw,cache= =3Dnone -serial mon:stdio -nographic

You will need firmware images for the latter.
