This goes long fine but ends with a message cant find /dev/root What next?
how do I get to have the dev dir creted on the new file system?
Many thx..




To do the install I downloaded the ISO to my x86 machine, and used the 
x86 httpd server to perform the install.

With the httpd server running and the ISO mounted at a location httpd 
could access.
     mkdir /var/www/html/install/DVD1/
     mount -o loop Fedora-Server-DVD-s390x-23.iso 
/var/www/html/install/DVD1/

I started hercules and issued this command to begin the install;
     ipl ks-lvm.ins

where ks-lvm.ins is:

You need a root= statement in the generic.prm file. For example here’s what we use for a
RHEL7 ISO mounted on an internal NFS server:

root=live:nfs://172.17.16.45/export/redhat/rhel7/s390x/iso/images/install.img

Sorry that my notes on installing f23 s390x didn't work.
Perhaps issuing these commands before starting hercules are the missing piece, idk.
      echo 1 > /proc/sys/net/ipv4/ip_forward
      iptables -t nat -A POSTROUTING -s 192.168.200.0/24 -d 0.0.0.0/0 -j MASQUERADE
      systemctl stop firewalld

If the install stalls with the /dev/root message again, when you are dropped into the
dracut(?) shell, enter this command in the hercules window.
     .cat /run/initramfs/rdsosreport.txt

Then exit hercules and browse your hercules.log file for the cat of rdsosreport.txt and
look for errors.
I think this is the error I had with f23 when I didn't stop firewalld. 
  Failed to connect to 192.168.200.4 port 80: No route to host
