Running AIX 7.2 TL3SP1 on x86_64 via qemu-system-ppc64

Who would not wish to run the best operating system on earth on his pity Intel Laptop ? I will describe here what I have done with the help of others and share some of my findings and recommendations how to get this going.

For this exercise Im using Linux Mint 19 x86_64 and current qemu compiled from source which you can get from here https://github.com/qemu/qemu

One should get the similar output from the compilation

$ git clone git://git.qemu.org/qemu.git
$ cd gemu 
$ mkdir build
$ cd build
$ ../configure
$ make
$ su 
# make install 
# exit 
$  qemu-system-ppc64 --version
QEMU emulator version 3.0.50 (v3.0.0-614-g19b599f766-dirty)
Copyright (c) 2003-2017 Fabrice Bellard and the QEMU Project developers

So once we have qemu installed we can then move on to get an actual AIX ISO, which I cannot obviously share, but I will link some already made documentation how to get it done if you already have a Power environment with AIX on

https://www.ibm.com/developerworks/community/blogs/cgaix/resource/AIX_QEMU_blog.pdf?lang=en_us

Next I will share my tun-tap scripts as well as the installer loader and normal loader scripts for the AIX

Here is my standard Linux networking script that I use for various VMs and simulators (VirtualBox, Alphavm-free, simh, hercules )

#Setup tap and bridge 
tunctl -t tap0 -u user
ifconfig tap0 up
brctl addbr br0
brctl addif br0 enp0s25 vboxnet0 
brctl setfd br0 0
ifconfig enp0s25 10.0.2.1 up 
ifconfig br0 10.0.2.2 netmask 255.255.255.0 broadcast 10.0.2.255 up
brctl addif br0 tap0 vboxnet0 
ifconfig tap0 0.0.0.0
sysctl net.ipv4.ip_forward=1
iptables -A FORWARD --in-interface enp0s25 -j ACCEPT
iptables --table nat -A POSTROUTING --out-interface wlp9s0 -j MASQUERADE

Please change accordingly to your need, enp0s25 is eth0, wlp9s0 is wlan0 that is internet connected.

Here is a slightly modified /etc/qemu-ifup

#! /bin/sh
# Script to bring a network (tap) device for qemu up.
# The idea is to add the tap device to the same bridge
# as we have default routing to.

# in order to be able to find brctl
PATH=$PATH:/sbin:/usr/sbin
ip=$(which ip)

if [ -n "$ip" ]; then
ip link set "$1" up
else
brctl=$(which brctl)
if [ ! "$ip" -o ! "$brctl" ]; then
echo "W: $0: not doing any bridge processing: neither ip nor brctl utility not found" >&2
exit 0
fi
ifconfig "$1" 0.0.0.0 up
fi

switch=$(ip route ls |
awk '/^default / {
for(i=0;i<NF;i++) { if ($i == "dev") { print $(i+1); next; } }
}'
)

switch=br0

# only add the interface to default-route bridge if we
# have such interface (with default route) and if that
# interface is actually a bridge.
# It is possible to have several default routes too
for br in $switch; do
if [ -d /sys/class/net/$br/bridge/. ]; then
if [ -n "$ip" ]; then
ip link set "$1" master "$br"
else
brctl addif $br "$1"
fi
exit # exit with status of the previous command
fi
done

echo "W: $0: no bridge for guest interface found" >&2

Next is my AIX 7.2 TL3SP1 installation loader script

qemu-system-ppc64 -cpu POWER8 -machine pseries -m 2048 -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

And here is the simulation loader script

qemu-system-ppc64 -cpu POWER8 -machine pseries -m 2048 -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='boot disk: ' -net nic -net tap -display vnc=:1

My disk.img is a standard qcow2 compressed image format (100 G)

Once the system is installed ( please use this reference https://www.ibm.com/developerworks/community/blogs/cgaix/resource/AIX_QEMU_blog.pdf?lang=en_us )

Be patient once it all loads (takes approx 5 minutes on my Panasonic CF-53 ToughBook  with Intel(R) Core(TM) i5-3320M CPU @ 2.60GHz

Following are my additional steps that I have done after loggin in the first time after install (the /etc/motd is my own custom one)

AIX 7.2 networking

# ifconfig en0 10.0.2.10 up
# route add 0 10.0.2.2 
# chdev -l inet0 -a hostname=asterix
Add following to 

# echo "nameserver 8.8.8.8" > /etc/resolv.conf 

To make it persistent created a scritp in /etc/network.sh

#!/bin/ksh
echo "nameserver 8.8.8.8" > /etc/resolv.conf
ifconfig en0 10.0.2.10 up
route add 0 10.0.2.2

And made it executable of course

# chmod +x /etc/network.sh

Then added last entry to /etc/inittab so next time we boot, network works

customnet:2:once:/etc/network.sh 2>&1

Test the above, reboot the machine by issuing halt command an re-loading it.

Important thing to notice here – do not use the -serial stdio interface in your terminal for normal work. CTRL-C will kill the qemu simulation and thats something you don’t want. So setup sshd instead (I have allowed remote root user for simplicitys sake here) and connect to your guest AIX via ssh from the Linux host !

Connect to the AIX guest (you can then make as many ssh sessions as needed, once AIX guest is booted its quite fast to use taking into consideration all Power8 instructions are simulated by qemu)

Here are the details about the guest AIX

Configure YUM

Please read the documentation here about how to setup the environment
https://public.dhe.ibm.com/aix/freeSoftware/aixtoolbox/ezinstall/ppc/README-yum

Since we have no tools yet installed I will use my Linux Host machine to download all the needed RPMs and then copy them to AIX guest via scp

// On the Linux Host machine 
$ mkdir AIX 
$ cd AIX 
$ wget https://public.dhe.ibm.com/aix/freeSoftware/aixtoolbox/ezinstall/ppc/yum_bundle.tar

// On the AIX guest 
# mkdir /tmp/RPM
# cd /tmp/RPM
# scp user@10.0.2.2:/home/user/AIX/yum_bundle.tar . 
# tar -xv yum_bundle.tar

Install RPMs on the AIX guest

# cd /tmp/RPM
# rpm -ivh ca-certificates-2016.10.7-2.aix6.1.ppc.rpm
# rpm -ivh curl-7.52.1-1.aix6.1.ppc.rpm
# rpm -ivh db-4.8.24-3.aix6.1.ppc.rpm
# rpm -ivh gdbm-1.8.3-5.aix5.2.ppc.rpm
# rpm -ivh gettext-0.19.7-1.aix6.1.ppc.rpm
# rpm -ivh glib2-2.14.6-2.aix5.2.ppc.rpm
# rpm -ivh readline-6.1-2.aix6.1.ppc.rpm
# rpm -ivh sqlite-3.15.2-1.aix6.1.ppc.rpm
# rpm -ivh python-2.7.10-1.aix6.1.ppc.rpm
# rpm -ivh python-devel-2.7.10-1.aix6.1.ppc.rpm
# rpm -ivh python-iniparse-0.4-1.aix6.1.noarch.rpm
# rpm -ivh python-pycurl-7.19.3-1.aix6.1.ppc.rpm
# rpm -ivh python-tools-2.7.10-1.aix6.1.ppc.rpm
# rpm -ivh python-urlgrabber-3.10.1-1.aix6.1.noarch.rpm
# rpm -ivh pysqlite-1.1.7-2.aix6.1.ppc.rpm
# rpm -ivh yum-metadata-parser-1.1.4-2.aix6.1.ppc.rpm
# rpm -ivh yum-3.4.3-5.aix6.1.noarch.rpm

Now YUM is ready to install some tools

# yum install tcsh 
# yum install gcc

If there are problems with RPM db afterwards, simply rebuild it

# rpm --rebuilddb

I do not know how to work in Korn shell (default) too much so I have installed tcsh

# yum install tcsh

And setup the environment to use it  /etc/passwd entry for root

root:!:0:0::/home/root:/usr/bin/tcsh

And then configure tcsh prompt for the root user

# cd /home/root 
# cat .cshrc 
set prompt = '[%n@%m %c]# '

PKGSRC Q3-2018 test

Next I have tested pkgsrc build, please make sure you read the following https://wiki.netbsd.org/pkgsrc/how_to_use_pkgsrc_on_aix/

# ftp ftp.netbsd.org 
230 Guest login ok, access restrictions apply.
ftp> pas
Passive mode on.
ftp> bin
200 Type set to I.
ftp> cd /pub/pkgsrc/pkgsrc-2018Q3
ftp> get pkgsrc.tar.gz

# mv pkgsrc.tar.gz /tmp
# cd /tmp
# gunzip pkgsrc.tar.gz 
# tar -xvf pkgsrc.tar
# setenv CC /opt/freeware/bin/gcc 
# cd pkgsrc/bootsrap
# ./bootstrap

After bootstrap make sure we declare the following variables in TCSH

# setenv CC /opt/freeware/bin/gcc
# setenv USE_NATIVE_GCC yes

Then we can build pkgsrc packages as follows

# /usr/pkg/bin/bmake install clean

P.S

What does not work

  •  Bash (bash_64 cpu 95%)
  •  Wget – core dump
  •  Ruby (cpu 95%)
  •  ps (core dump) – using topas instead   (another workaround is to use /usr/sysv/bin/ps which is a RISC System/6000 binary, so you can move /usr/bin/ps away and symlink the above ) Thanks Russ !
  •  vmstat – using topas instead

Update on why things do not work 11.11.2018 

The problem is that on AIX binaries usually come in two forms – 32 bit ((RISC System/6000)   and 64-bit XCOFF  these files are usually identified as filename_32 and filename_64 under /opt/freeware/bin for example. Inside you get symlinks to either the 32 or 64 version of the file, so keep in mind that under Qemu not all 64-bit XCOFF binaries work as expected and some coredump. To fix this you need to change the symlinks to point to 32bit versions ( this fixes ruby, bash, wget, curl etc) however not the ps command since that is shipped by the OS as 64bit version only.

  1. Phill says:

    Why not use smitty mktcpip to set up the AIX network interface and dns resolution the standard way instead of a work-around?

    • astr0baby says:

      Yeah .. I know, even though I have worked on many AIX systems I never really liked Smitty … but good point, smitty works in the emulation just fine.

      • darkfader says:

        smitty is just a layer on top on some intermediary commands on top of the actual commands.
        so there’s most certainly some chattr you can run instead of bothering with smitty :-)

      • astr0baby says:

        Yes, definitely, I do not like smitty actually, but most AIX admins are hammered to use it since child-hood :)

  2. Russ says:

    AIX ships with a sysv verson of ps, this works OK and might do as a workaround for some situations. Just use the path /usr/sysv/bin/ps.

    Hello,
    I have issues with the latest 7.2 GA installation with latest qemu-system-ppc64, the qcow2 disk is seen by the openfirmware but not by AIX , I have no available disks destinations.
    I am using
    -drive file=/data/disk.img,if=none,id=drive-virtio-disk0 \
    -device virtio-scsi-pci,id=scsi -device scsi-hd,drive=drive-virtio-disk0 \

    100000000000000 DISK : “QEMU QEMU HARDDISK 2.5+”

    do you need to load some special drivers?
    Thanks
    g.

    • astr0baby says:

      You need to run AIX 7.2 TL3SP1 minimum, as the kernel in this Technology Level and Service Pack contains the needed virtio support.

      • golemwashere says:

        Thanks!
        I was using first AIX DVD instead of the huge AIX_v7.2_Install_7200-03-02-1846_flash_112018.iso which looks like it has neede drivers.
        I managed to install and bring up en0 on a tap device.
        FTP works fine but I have issues with openssh :
        connections always fail with ssh_dispatch_run_fatal: Connection to xxxx port 22: incorrect signature.

        I tried messing with KeyHex and Cypher algorithms in sshd_config.
        I tried regenerating ssh keys.
        I tried to downgrade openssh from OpenSSH_7.5.102.1600, to OpenSSH_7.5.102.1100 or OpenSSH_6.0.0.6204 but no luck
        I was considering downgrading openssl ( current version is 1.0.2.1601 )
        but there are some dependencies I’d rather not touch
        Do you have any suggestion?

      • astr0baby says:

        OpenSSH worked for me with no problems, I will spin-up the VM today and send you the software versions so you can check.

      • astr0baby says:

    Hello, Thanks a lot for support…
    I think I was having problems with my tap and br devices (I had put IP both on tap0 and br0) …
    and having IPs on the same network for multiple devices might have confused ssh.
    I have you same exact versions.

    Starting from scratch I managed to reach by ssh the aixonqemu ip from the host mac
    but I can’t reach anything from inside to outside.

    currently I have qemu starting with
    -net nic -net tap
    this is creating a tap0 device

    on linux (latest Centos7),
    my first interface with its default gateway is ens192 on network 1.1.1.0/24 vlan1 and I wish to use my other interface ens224 on network 2.2.2.0/24 vlan2 (addresses changed to protect the innocent)

    this is what I am currently doing to configure br0

    ifconfig tap0 up
    brctl addbr br0
    brctl addif br0 tap0
    brctl addif br0 ens224
    brctl setfd br0 0
    ifconfig ens224 up
    ifconfig br0 up
    ifconfig br0 2.2.2.5 netmask 255.255.255.0

    on aixonqemu I configured en0 with 2.2.2.2 and that is reachable by the linux host
    (but not any other host in vlan2 , while hosts in lan reach 2.2.2.5)
    a tcpdump on en0 is showing all broadcast traffic for vlan2
    but from inside aixonqemu
    but I can’t reach anything but 2.2.2.5

    I think I need some masquerading with iptables,
    I tried something as

    iptables -A FORWARD -i tap0 -o ens192 -j ACCEPT
    iptables -t nat -A POSTROUTING -o ens192 -j MASQUERADE
    iptables -A FORWARD -i tap0 -o ens192 -m state –state ESTABLISHED,RELATED -j ACCEPT
    pls forgive my n00bness on tap and br0 devices,
    do you have any suggestion?

    • astr0baby says:

      Lets make this simple :)
      Below is the simplest network config you should use

      tunctl -t tap0 -u user
      ifconfig tap0 up
      brctl addbr br0
      brctl addif br0
      brctl setfd br0 0
      ifconfig br0 10.0.2.2 netmask 255.255.255.0 broadcast 10.0.2.255 up
      brctl addif br0 tap0
      ifconfig tap0 0.0.0.0
      sysctl net.ipv4.ip_forward=1
      iptables –table nat -A POSTROUTING –out-interface wlan0 -j MASQUERADE

      Explanation:
      bridge0 : 10.0.2.2 (would be the gateway for the aixonqemu

      Inside aixonqemu
      en0 : 10.0.2.10 (add default route 10.0.2.2 and DNS 8.8.8.8 or whatever else)

      Make sure we also portforward to the internet (I use wlan0 on my laptop so you need to adjust to whatever is your internet connected device) thus :

      sysctl net.ipv4.ip_forward=1
      iptables –table nat -A POSTROUTING –out-interface wlan0 -j MASQUERADE

  6. golemwashere says:

    dude you’re THE MAN!
    using br0 ip address on aixonqemu as gateway and masquerading on ens192 ( wlan0 ) works fine!
    now I could also install and use yum, bash (32bit) , etc
    Still not grokking much the tap0 / br0 stuff , I wished you could just publish on a layer2 interface the internal aix IP.
    My next fun would be testing samba on aix through some iptables portfowarding from my wlan0 interface.
    Thanks a lot again for insight!

  7. Hello

    • astr0baby says:

      you have bridgeutils installed ?, also please remove the vboxnet0 from the brctl command (you probably do not want that if you do not
      wish to add vboxnet0 to the br0)

  10. MJ says:

    Hey astrobaby,

    Can you release for download your qemu disk image file with aix 7.2 installed?
    Im stuck with the basic shell of the diagnostic disk and I dont have a aix 7.2 to generate a mksysb from :(

  11. MJ says:

    Yeah, I remember a long time ago I tried rsync over ssh and it was painfully slow because of the encryption overhead of ssh.

  12. MJ says:

    Confirmed that /dev/random was introduced in AIX 5.2:

    “The AIX 5.2 base security provides new pseudo random number generator devices, /dev/random and /dev/urandomM, pseudo-device driver and configuration routines that select various hardware device interrupts to provide entropy. OpenSSH in AIX 5.2 is compiled to take advantage of the new device /dev/urandom. You will also need the latest OpenSSL version, openssl-0.9.6e-2.aix4.3.ppc.rpm (AIX Linux Toolbox), for OpenSSH to use the /dev/urandom device.”

    source: https://www.ibm.com/developerworks/systems/articles/openssh_updated.html

  13. MJ says:

    Hey Astr0, why you used POWER8 instead of POWER9?

  14. MJ says:

    I’m not sure,
    I’m asking because that in the reference guide that you linked, they have used POWER9. Thinking in simulation simplicity we can also use POWER7.

    I will bench to see.

    • astr0baby says:

      I have never used P9 really … would be great to see if P7 would boot the qemu-system-ppc64 has any speed advantage over P8 and P9. Would be great to know :)

  15. Marlon Anjos says:

    Hey @ast0baby, I tested the simulation using various processors and there are little difference in performance:

    Time to boot (AIX mksysb ISO)
    Power 7: 4m38s
    Power 8: 4m44s
    Power 9: 4m50s

  16. linuxgeek says:

    Hi astrobaby,

    is it possible to add additional disks with the above configuration. It will be helpful in creating new VGs

    • astr0baby says:

      Certainly, you need to create blanks first in your hosting system (Linux) via qemu-img create -f qcow2 … then add the disk path to the qemu loader script (assign proper SCSI id)
      Possibly like this
      -drive file=new.img,if=none,id=drive-virtio-disk1 -device virtio-scsi-pci,id=scsi1 -device scsi-hd,drive=drive-virtio-disk1

    I get the below error.
    qemu-system-ppc64: -device virtio-scsi-pci,id=scsi: Duplicate ID ‘scsi’ for device
    Below is the script i am using.

      Spotted the mistake. New to using qemu-kvm.

      qemu-system-ppc64 -cpu POWER7 -machine pseries -m 3072 -serial stdio -drive file=AIX72.img,if=none,id=drive-virtio-disk0 -device virtio-scsi-pci,id=scsi -device scsi-hd,drive=drive-virtio-disk0 -drive file=AIX73.img,if=none,id=drive-virtio-disk1 -device virtio-scsi-pci,id=scsi1 -device scsi-hd,drive=drive-virtio-disk1 -cdrom Aix72.iso -prom-env boot-command=’boot disk:’

  18. linuxgeek says:

    I am running this on qemu-kvm providing 3G of memory in Lenovo G50. I am using Power 7 as I get some warnings or error like TCG support problem in Power8/9. The performance is fine but I am feeling the slowness in command execution. Perhaps I should try running it with my desktop by upgrading it to 8G memory to see the performance.

    Hi astrobaby,

    When I am trying to user four disks, the booting process stops and comes out. Is there any limitations on the disk being used. Below is the script I am using. It stops in the midway with below codes to the prompt.

    • astr0baby says:

      I tried this with 2 disks, it works fine. Not sure if there is any limitation in Qemu for this (doubt there is since the virtio-scsi controller can have up to 256 “targets”). Does it work with 2 and 3 ?

  20. linuxgeek says:

    Yes. Sometimes it works with 3 disks, but also fails with the same configuration.

    • linuxgeek says:

      While executing the command. it shows the sign ^@ while the command is running. I didn’t see it in your videos.

      # lsvg rootvg
      ^@VOLUME GROUP: rootvg VG IDENTIFIER: 00000000000000000000016b97bc6ee7
      VG STATE: active PP SIZE: 256 megabyte(s)

      • astr0baby says:

        Im using an older qemu-system-ppc64 build, the new ones are buggy for AIX. My version that works well is QEMU emulator version 3.0.50 (v3.0.0-614-g19b599f766-dirty)
        try to get this one via git

  21. linuxgeek says:

    Configured networking based on your script. The tun/tap configuration is not static. When I shutdown the system it disappears. While using ssh shell it looks normal, I dont see the ^@. Weird. Thanks for your response.

      Try creating a clean installation ISO on your NIM server. Im not entirely sure what the bos.sysmgt.serv_aid package is for
      You can see it coredumps at a certain level

      Did you try to boot the dist afterwards ?

    is there any way to get additional network interfaces in AIX. My desktop has 2 NIC cards. If I run this disk in it, Will I be able to get those NIC in the OS. Also is there any way to get Virtual NIC so that I will be glad to learn etherchannel concepts.
