Re: AIX 7.2 guest, Windows 10 host, networking, qemu 6.0.50.

Hi Paul,

I'm CC'ing the overall QEMU mailing list as well to increase the chance
of finding someone that runs QEMU on Windows.

This is a working example of an AIX guest with network using the spapr-vlan
net device:

-M pseries,ic-mode=xics -cpu POWER9 -smp 2 \
-device spapr-vlan,netdev=net0,mac=52:54:00:49:53:14 \
-netdev tap,id=net0,helper=/usr/libexec/qemu-bridge-helper,br=virbr0 \
-device virtio-scsi,id=scsi0 \
-drive file=./disk.qcow2,if=none,id=drive-scsi0-0-0-0,format=qcow2,cache=none \
-device 
scsi-hd,bus=scsi0.0,channel=0,scsi-id=0,lun=0,drive=drive-scsi0-0-0-0,id=scsi0-0-0-0,bootindex=1

I've never tried to run QEMU using Windows. I'll give a try when I have the
chance. I guess that one core difference is how you'll create the network
bridge for the guest.


Which command line did you use to create the AIX guest?

An even greater achievement would be to make it work under a Windows 10 host :D


Take care,
