    I installed Fedora 7 in another new partition and backed up original etc,bin,sbin,lib,usr,var
    from older Fedora 7 and copied new etc,bin,sbin,lib,usr and var into older Fedora.

    now i'm getting more info on problem,

    screen displayed a message similar to below
    example kernel: audit(1009218137.105:0): \
    avc: denied { read } for pid=16202 exe=/bin/bash
    and the log messages show this
    SELinux is preventing /bin/login (hotplug_t) "entrypoint" to /bin/bash (etc_runtime_t). For complete SELinux messages. run sealert -l 8ba8d372-9a71-456c-8d13-9b792c5c4a69
    What's the issue here? Should i disable SELinux ?

    Any thoughts post here ,in the mean time i'll continue my own exploration

    I don't suppose you backed up your system first? What about your boot menu? Can you boot the old kernel as an option? Remember, Xen is a different kernel version. It can co-exist on your system with a non-xen kernel. However, it is possible that what you did has munged the entire system and you may need to restore from backup, or reinstall altogether. You haven't provided enough information as yet to determine what you can do to fix this.

    In my case, whenever I am going to do something that will potentially jeopardize my system, I make a bit-image of the system disc, so I can easily "roll back" the changes simply by restoring the old version in its entirety. Ie, I backup the entire disc, not just some partitions, including the boot sector.

    The thing about removing "unwanted" files from systems like Linux is that they might not be so unwanted as you think. Remember, that you can delete a file that is in use, such as a shared library, but while it may not appear in the directory, it actually hasn't been removed from the system until the applications that are using it are shut down. So, when you rebooted, these files are physically removed from the system (their link count == 0), and now your system won't run. Caveat User. Don't remove files, directories, or programs from /usr, /var, /opt, /bin, /sbin, /boot, /lib (and /lib64), or /etc and their sub-directories if you don't know EXACTLY what you are doing! Whether or not you can recover from this without reconstructing your entire system is debatable.
