    Most likely you are running off the non virtualized kernel.

    SSH to the server then use vi or nano to check and make sure you are booting off the correct kernel.
    The file you need to check is /boot/grub/grub.conf

    That is a hetzner-generated file, are you reading the grub.conf from inside the VPS -- it seems like you're not.

    What type of VPS is it? I assume it's KVM.

    Yes indeed is In Hetzner and indeed is KVM.
    This file is from main server SSH.
    I cannot SSH to vps I can access them only from solus panel in vnc when I get Grub> line only

    One more thing , I have in same server one Windows installation which work perfect.
    So I guess I must fix the grub loader in vps.
    But I get only command line
    Grub>
    There.
