Entire case started with project for p2v migration of old SCO machines. One of the machines had entire directory tar'ed and then we had to deploy virtual one. OVF eventually was deployed, but after comparison of disk setup of Physical with Virtual I though that root partition should be extended, as physical one had 2GB of space more. That's why the question in that thread. Eventually I'v noticed that Physical one has only 4GB of space used so Virtual machine is fine, I just needed another partition, and that was easy task.
Then, having virtual machine deployed i started restoring backed up tar files and restoring them on virtual as it is. I was prepared for some configs to be modified (/etc/fstab, etc.). But it turned out that partition table got messed up, so I tried and tried. Eventually I'v got to the point I described, I've noticed that actually all important things are in /opt/{K,P}, so I've first tar'ed those directories on virtual machine, restored physical machine tars, and overwritten what I previously tared on virtual one. And that allowed me to boot the machine without one error during boot procedure. But I don't know if that's proper way to migrate (for sure not) and if all services that supposed to start started (I a assume no errors means something).
Maybe you already know better procedure for doing such migration in diy way, without use of enterprise software. If teams that will test it tell me that I doeasn't work as it should I'll start reading documentation for Backup/RestoreEDGE and other software that was posted here.
Still thanks for all help, and If you have more suggestions I will be glad to read them.

fence_zvm
fence_zvm(8) System Manager's Manual fence_zvm(8)
NAME
fence_zvm - I/O Fencing agent for GFS on s390 and zSeries VM clusters
SYNOPSIS
fence_zvm [OPTION]...
DESCRIPTION
fence_zvm is an I/O Fencing agent used on a GFS virtual machine in a s390 or zSeries VM cluster. It uses the s3270 program to log the
specified virtual machine out of VM. For fence_zvm to execute correctly, you must have s3270 in your PATH.
fence_zvm accepts options on the command line as well as from stdin. fence_node sends the options through stdin when it execs the agent.
fence_zvm can be run by itself with command line options which is useful for testing.
Vendor URL: http://www.ibm.com
OPTIONS
-a IPaddress
IP address or hostname of the Physical machine (required).
-h Print out a help message describing available options, then exit.
-u userid
userid of the virtual machine to fence (required).
-p password
password of the virtual machine to fence (required).
-S path
Full path to an executable to generate the password of the virtual machine to fence.
-q quiet mode, no output.
-V Print out a version message, then exit.
STDIN PARAMETERS
agent = < param >
This option is used by fence_node(8) and is ignored by fence_zvm.
ipaddr = < hostname | ip >
IP address or hostname of the Physical machine (required).
passwd = < param >
password of the virtual machine to fence (required).
passwd_script = < param >
Full path to an executable to generate the password of the virtual machine to fence.
userid = < param >
userid of the virtual machine to fence (required).
