    Regarding the "kvm: disabled by bios" message. If you want to suppress that you can blacklist the kvm modules.

    create a file named "50-blacklist-kvm.conf" in "/etc/modprobe.d" with the following content:
    Code:
    # blacklist kvm modules (suppresses "kvm: disabled by bios" message at boot)
    blacklist kvm
    blacklist kvm_intel
    blacklist kvm_amd
    Alternatively, just enable kvm in the bios.

    after create the file "kvm: disabled by bios" message disappears, it work. but still shutdown/boot text is hidden, only see tty1 windows.

    is there's some how to see the kernel parameters options from outside of the cinnamon environment.

    this the current parameters from inside the environment using yast(is it correct):

    Code:
    splash=verbose resume=/dev/disk/by-uuid/fb735f35-4f57-4bef-a338-3a8b25b63ba2 quiet

    cat /proc/cmdline
    will show the command line used on boot.

    There's a surplus "quiet" at the end of the line.

    As a follow up on this, and relating to your "missing" boot/shutdown test, all my own systems are set up to have:

    All "plymouth" packages removed.

    The "splash=" and "quiet" options removed and "loglevel=3" added.

    Which gives console boot messages sufficient for my requirements.

    For reference these are the available loglevels:

    Code:
    loglevel=       All Kernel Messages with a loglevel smaller than the
                    console loglevel will be printed to the console. The
                    loglevels are defined as follows:
    
                        0 (KERN_EMERG)          system is unusable
                        1 (KERN_ALERT)          action must be taken immediately
                        2 (KERN_CRIT)           critical conditions
                        3 (KERN_ERR)            error conditions
                        4 (KERN_WARNING)        warning conditions
                        5 (KERN_NOTICE)         normal but significant condition
                        6 (KERN_INFO)           informational
                        7 (KERN_DEBUG)          debug-level messages

    remove "quiet", return the scroll text again. but also i believe it show the scroll text for loading ramdisk. also set "loglevels", give same results. in general it good enough for me.

    still my advice for any one read the thread in feature, just do not install "plymouth" from the beginning (if you do not need the flash image).

    many thanks for support
