Hello Yuval,
sorry for my late response! I installed from a USB stick... I try it now again on a second machine and the exact message is:

   *Failed to open \EFI\centos\grubx64.efi - Not Found**
   **Fail to load image \EFI\centos\grubx64.efi - Not Found**
   **start... image() returned Not Found*

What Brian Barry recommend didn't work for me to. I booted again from the stick and choice Troubleshooting, there I can select "1", this should mount my installation to a folder, but the starting process ended up in a loop, where error comes up saying something about error on line 9. After a second round I lost my patience and I install again the normal centos minimal.

Is there any performance benefit with installing from oVirt Node?

Regards
Jonathan

Hi,

We did have some problems in the past with efi, but they should be fixed by now. Did you use the ISO for installation ?  What error are you seeing - which file is missing there ?

Thanks,
Yuval.

    Thank you, good to know that this works! I need to play a bit with
    it.

        Yes, I use power management with ipmilan, no issues.

        I do have license on the IMM for remote console, but that is not a
        requirement, AFAIK.

        I remember I first tried to use for oVirt a dedicated login on
        the IMM
        with just "Remote Server Power/Restart Access" and I could not
        get to
        work, so I just granted "Supervisor" to the dedicated login.
        Other than
        that, no problem.

            Thank you, for your commands! I have now also install
            CentOS minimal,
            this works. I only though that oVirt Node have some
            optimizations, but
            maybe not.

            @Eduardo Mayoral, can I ask you that you are able with
            this servers,
            to use the power management? As I understand, they support
            ipmilan,
            but I don't know how...

                I have seen this problem before. For some reason,
                oVirt Node 4.1.x
                does not always install everything right for efi. In
                my limited
                experience, it fails to do it correctly 4 out of 5
                times. The mystery
                to me is why it gets it right sometimes. I solve the
                problem by
                manually copying the missing file into my efi boot
                partition.

                    I remember I had a bad time trying to disable UEFI

                    those servers. In my opinion, the firmware in that
                    model ridden with
                    problems. In the end, I installed with UEFI (You
                    will need a
                    /boot/efi partition)

                    Once installed, I have not had any issues with them.

                        Hello everybody,
                        I would like to install oVirt Node on a IBM
                        Machine, but after the
                        installation it can not boot. I get the message:

                        "/boot/efi/..." file not found

                        I try many different things like turn of uefi
                        options in bios etc.
                        but with no effect.

                        Now I figure out that when I install full
                        CentOS 7.3 from live DVD
                        it just boot normal.

                        Is there any workaround to get this to work?

                        Regards
