I chose OpenSuSE 12.3 as host OS, this is my network topology:
+--------------Host OS OpenSuSE----
|127.0.0.1 (lo)
|192.168.11.19 (eth0)
|192.168.10.20 (tun0)
|
|..+-----------Hercules------------
|..|192.168.10.21
|..|
|..|..+--------CentOS--------------
|..|..|192.168.10.22
|..|..+----------------------------
|..|
|..+-------------------------------
This is a typical home topology, I have a router (it also works as a LAN switch and a Wi-Fi AP), a laptop, a desktop PC (I'm using this to run Hercules) etc. Using this topology your emulated OSes will be able to reach your home network and Internet, and this is true reverse.
Disable Network Manager:
Open a console, then start yast, select Network Devices -> Network Settings -> Global Options.
Network Setup Method: Traditional Method with ifup
(Here I disabled IPv6, because I don't use it.)
By navigating in this Yast module, setup your eth0 network card. I'm using these settings:
Overview (select the network card):
IP Address: 192.168.11.19, Subnet Mask: /24 (/24 means 255.255.255.0)
(I'm using a router to reach Internet.)
Hostname/DNS
Hostname: probe, Domain Name: home, Name Server1: 192.168.11.1
Routing
Default IPv4 Gateway: 192.168.11.1
Check if tun device is available (it exists by default, if not, use Yast to add it):
probe:~ # ls -l /dev/net/tun
crw-rw-rw- 1 root root 10, 200 May 29 15:51 /dev/net/tun
Disable SuSE Firewall, I don't know exactly why, but IP forwarding wasn't working perfectly when I turned on the firewall. Btw, this is a Linux, behind a router, it doesn't store sensitive data, I see no reason for a firewall.
yast -> Security and Users -> Firewall
alt+d Disable Firewall Automatic Starting
alt+v Save Settings and Restart Firewall Now
Finish, Quit.

>>>>>>CentOS part<<<<<<
Download CentOS 4.7 s390, 4.7 is the latest version which supports S/390.
Link: vault.centos.org/4.9/isos/s390/centos-4.7-s390-bindvd.torrent
After you torrented down the ISO file, seed it please, it's important.
As CentOS 4.7 is no longer available via HTTP/FTP, and we downloaded the installation DVD, let's share it via NFS:
probe:~ # zypper install yast2-nfs-server nfs-kernel-server
Then start yast -> Network Services -> NFS Server
NFS Server: Start
Firewall Settings: [x] Open Port in Firewall (for future usage, as I have no firewall at the moment)
Enter NFSv4 domain name: home
Next -> Directories to Export -> Add Directory -> /export. Ok, Ok, Finish, Quit.
probe:~ # mkdir -p /export/centos47dvd
probe:~ # mount -o loop /ISO/cos47.iso /export/centos47dvd
(I renamed the original ISO file.)
Install Hercules:
probe:~ # zypper install hercules
Create your user, who will be running Hercules (I chose zop, it came from "a Z arch. operator"):
probe:~ # useradd -m zop
probe:~ # passwd zop
Create sudo access for zop. Hercules has to be run as root to create TUN interface(s) at startup. Of course I don't want to use root user to run Hercules directly, therefore I give limited root access to zop, zop will be able:
- to run Hercules as root,
- to run the script which sets up IP forwarding, also as root.
probe:~ # visudo
Find these lines:
Defaults targetpw # ask for the password of the target user i.e. root
ALL ALL=(ALL) ALL # WARNING! Only use this together with 'Defaults targetpw'!
And disable them, use hashmarks for this:
# Defaults targetpw # ask for the password of the target user i.e. root
# ALL ALL=(ALL) ALL # WARNING! Only use this together with 'Defaults targetpw'!
Find this line:
root ALL=(ALL) ALL
Then add here your primary admin user (this is adm in my case) below root (then you can forget your root password). Also add user zop.
adm ALL=(ALL) ALL
zop ALL=(ALL) NOPASSWD: /usr/bin/hercules, /usr/local/bin/zlinux1_net_setup
Create zlinux1_net_setup script. I edited /etc/sysctl.conf to enable IP forwarding, but no success. After reboot /proc/sys/net/ipv4/ip_forward contained 0, so I created a small script to enable IP forwarding manually.
probe:~ # touch /usr/local/bin/zlinux1_net_setup
probe:~ # chmod 700 /usr/local/bin/zlinux1_net_setup
probe:~ # vi /usr/local/bin/zlinux1_net_setup
(After vi has started, press i, it takes you to insert mode.)
#!/bin/bash
#This small script enables IP forwarding.
echo 1 > /proc/sys/net/ipv4/ip_forward
echo "IP forwarding has been set up."
Once you finished editing, press the ESC key, then :wq<enter> to save and exit.
Leave root, log in as zop. Then create your DASD, its type will be 3390-9. This is a well-known and widely used type of DASD devices, it takes ~8GB on your storage.

We got a new TUN interface created by Hercules, so we don't need to create it manually.
Check the host OS's router table, run the 'route' command (as root):

Let's continue, bring up CentOS installer:
Command ==> ipl /export/centos47dvd/generic.ins
Hercules provides a virtual serial line interface to the operating system you're running on Hercules. You can communicate with Hercules and the running OS in the same window (for Hercules commands type help then press enter). If you want to tell something to Hercules (for example: help) just type in. If you want to tell something to the running OS, then start the line with a simple . (dot) character.
Setup your OS on a virtual S390 box, step-by-step:

Wait for these messages:
Starting telnetd and sshd to allow login over the network.
Connect now to 192.168.10.22 to start the installation.
192.168.10.22 is reachable, we're gonna install CentOS. But first, we have to run the script we created above, so that we are able to reach our emulated OS from the outer world (outer means: out of the host OS).
Also there is one more additional step we have to do. Our host OS (where Hercules is running) knows how to reach 192.168.10.22, but the other hosts on the network don't. At this point, we have to tell everyone in our network how to reach zlinux1.
- If the host OS is a network gateway which is used as a default gateway for your network, then you don't have to do anything, 192.168.10.22 will be reachable from your entire network.
- If the host OS is not the (default) gateway for your network (this is the situation here, I use a cheap router at home), then you have to add a new route rule to your gateway/router.
Linux: route add 192.168.10.22 gw 192.168.11.19, then make it permanent.
Router: find the proper menu on the admin page of your router, this is "Advanced IP routing" in my case. Then add 192.168.10.22/32 (or 192.168.10.22/255.255.255.255) GW: 192.168.11.19.
Once you set up your gateway/router zlinux1 (192.168.10.22) will be reachable from the entire network. Later you can set up port forwarding for your gateway/router, if you want to reach your zlinux1 from Internet.
Let's continue with CentOS installation. Now it's time to telnet or ssh to your CentOS, I'm using telnet from the host machine, but remote access should work from other hosts in your network.

Now you can see the packages are being installed by Anaconda (the RedHat installer). Once it's done, push on reboot button. It won't do a real reboot. On Hercules main screen wait for these lines:

Now press the ESC key to see Hercules devices. Press ESC again to go back to the command line.
Then leave Hercules (type exit, now without a . character, as this command is for Hercules):
Command ==> exit
Now close everything and reboot your host OS, in order to check everything will be fine if you start your newly installed stuff after a host boot.
Log in to your "server" as zop from a remote machine, then start Hercules, CentOS, then keep them running in the background, without any opened terminal. Now I'm using my Debian box as client, not the host OS SuSE, but the user is the same, I'm using adm at home.
My laptop uses 192.168.11.51 IP address.
adm@cw:~$ ssh zop@192.168.11.19
Password:
zop@probe:~> screen -S h.centos47
#Here you got a new terminal. Check it:
zop@probe:~> screen -ls
There is a screen on:

1 Socket in /var/run/uscreens/S-zop.
#It's fine. Let's start Hercules:
zop@probe:~> cd h.centos47
zop@probe:~/h.centos47> sudo hercules -f centos47.cnf
Start the installed CentOS:
Command ==> ipl 0200
Wait 15 seconds at the chooser, then you will see:
We are running native (31 bit mode)
Our CentOS has started booting. It takes some minutes as Hercules emulates S/390 on x86, wait for these lines:
CentOS release 4.7 (Final)
Kernel 2.6.9-78.EL on an s390
zlinux1 login:

64 bytes from 192.168.10.22: icmp_seq=3 ttl=64 time=0.292 ms
Close this session by typing exit (or press CTRL+d), it brings back screen's window:0 with Hercules (if not press CTRL+a then 0). Detach this screen session, press CTRL+a then d, finally check if it's running in the background:
[detached from 6367.h.centos47]
zop@probe:~> screen -ls
There is a screen on:
6367.h.centos47 (Detached)
1 Socket in /var/run/uscreens/S-zop.
Now you can close this SSH connection, you can get back your Hercules by running 'screen -R <screenID>'. With screen utility you can keep one or more active terminals (with running programs) in the background. I use this solution, because Hercules needs an opened terminal to run, so I run it in a screen session, then I can drop the connection, Hercules will be running in the background without a real display, keyboard etc.

The DASD has been selected, activate it:
[Perform Action↓] -> Activate, it makes the DASD usable.
Press next, it takes you back to Disk Activation, press next again.
Installation Mode, (x) New Installation
Clock and Time Zone: (select the proper timezone here)
Region: Europe
Time Zone: Hungary
[x] Hardware Clock Set to UTC
Installation Settings: (I kept the default configuration, it will install 2.4GB of software. Later you can remove unneccessary packages, such as Gnome GUI. Or you can install SLES to a bigger DASD disk, or you can add more DASD disks to your existing environment.
Install -> Licences: I agree -> Install
At the end of the installation you will be asked to reboot the computer. This won't be a real reboot.
On Hercules main screen wait for these lines:
HHCCP042I SYSCONS interface inactive
Power down.
CPU0000: SIGP Stop and store status (09) CPU0000, PARM 00000000: CC 0
HHCCP010I CPU0000 store status completed.
Now (and in the future) type 'ipl 0200', your SLES will be up in a couple of minutes. If you have already set up networking (see it in CentOS installation process), you can log in to SLES via SSH.
Well, now you have a working SuSE Linux Enterprise Server on a "mainframe" ;-)
>>>>>>Conclusion<<<<<<
Hercules is a great and powerful, free and legal emulator, which opens the door to the world of mainframe computers. In the meanwhile I changed my host OS to Debian Linux, I dropper eth0 and I set up a bridge, finally I installed one more Linux on a Hercules VM, this is a Debian as well. Everything is working as a charm.
Cool stuff:
