    Thank you!<br>

    I'll try it out and check whether it works there. Otherwise I think
    it would be good to get rid of it.<br>

      Honestly, I dont know. I dont use either. Just heard it was broken
      in kvm, but it was there because of xen.<br>

              <div class="PlainText">Hi,<br>
                <br>
                When someone calls nova volume-attach or the
                block-device-mapping <br>
                parameter at boot, it is possible to specify a device
                name for the <br>
                guest. However I couldn't find any guest OS which would
                honor this. E.g. <br>
                with libvirt/kvm, if the guest has two virtio disks
                already (vda and <br>
                vdb), specifying vdf would be ignored and the disk will
                be attached as <br>
                vdc in the guest.<br>
                I propose to deprecate this option and at boot where it
                is not optional <br>
                to accept only auto as an option.<br>
                <br>
                Best regards,<br>
