    Hello Nahum,

    My apologize in the meantime I had found the solution with changing the
    IDE with the virtio, the ide is indeed limit to 4 devices but now it's
    running perfectly  thanks ;)

    But another question, do you have experience with adding raw devices in
    KVM ?

    Thanks in advance.

    Kind Regards,

    Dirk
