What to change after cloning (VmWare) RHEL

I am making a list of things to change after cloning (via VmWare) an instance of RHEL - what am I missing?

    * SSH KEY
    * Hostname in /etc/hosts and /etc/sysconfig/network
    * IP
    * Reregister the machine with RHN (this isn't working for some reason)

Host name and Ip address would be the most important portion that you need to take care of as soon as you finish cloning.

If you want the server to be identical then there is nothing much that need to be done.

For redhat registration, as far as I know one copy of OS can be registered only once, in case if you have multiple licenses, you may look in to logs to find out any hints. else better to contact Redhat. (Unfortunately my RedHat links are not working )

Hi

For my P2V on  Windows servers i always create some network files.
Example:
route print > Route_Settings.txt
ipconfig /all > IP_Settings.txt
wmic logicaldisk > Disk_Letters.txt

Just do the same for the Linux with Linux commands and save it on the physical machine, for further use.

If you use LVM disks you can get some boot issues, even you do use LVM disks.

You will need to Rebuild the ramdisk installer  /boot to boot the RH. Using the RH disc 1 and Linus rescue

Hope this can help
