We are discussing possibility to bring grub2 build from el8 into el7 via Satellite repos. In the meantime, the workaround is to download grubx64.efi from Fedora Rawhide or CentOS 9 Stream and replace /var/lib/tftpboot/grub2/grubx64.efi with it. Extracted version is also available here: https://people.redhat.com/~lzapleta/grub/grub2-efi-x64-2.04-35.fc34.x86_64/ This is a support exception for HTTP UEFI Boot scenarios. QA: Please just confirm the workaround works for EL7 and for Capsule running on EL8 please verify the workflow, thank you! VERIFIED satellite-6.11.0-1.el8sat.noarch grub2-efi-x64-2.02-123.el8.x86_64 - I entered the setup utility of my UEFI-based VM and used HTTPboot directly from there. the grub2 was successfully pulled: ``` ==> /var/log/foreman-proxy/proxy.log <== 2022-05-24T07:45:03 59e55e3a [I] Started HEAD /httpboot/grub2/grubx64.efi 2022-05-24T07:45:03 59e55e3a [I] Finished HEAD /httpboot/grub2/grubx64.efi with 200 (1.63 ms) 2022-05-24T07:45:03 75d83e3d [I] Started GET /httpboot/grub2/grubx64.efi 2022-05-24T07:45:03 75d83e3d [I] Finished GET /httpboot/grub2/grubx64.efi with 200 (0.46 ms) ``` and loaded - next, the kicstart kicked in and the rest of automatized installation passed. after the installation was finished and an updated grub config was generated, the VM was rebooted and successfully httpbooted the updated grub+config again. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA. For information on the advisory (Moderate: Satellite 6.11 Release), and where to find the updated files, follow the link below. If the solution does not work for you, open a new bug report. https://access.redhat.com/errata/RHSA-2022:5498 |
Created attachment 1822947 [details] screenshot of OVMF firmware trying to load grub2 using httpboot Description of problem: HTTPBoot seems not to be able to load the GRUB2 version provided by RHEL7: grub2-efi-x64-2.02-0.87.el7_9.6.x86_64 Since satellite uses the GRUB provided by the underlying OS, this blocks the usage of httpboot pxeloader during host provisioning. This works with GRUB2 provided by RHEL8: grub2-efi-x64-2.02-99.el8.x86_64.rpm So the workaround would be to manually replace the GRUB binary located in the tftpboot by the new one. Version-Release number of selected component (if applicable): All satellite versions (installed on rhel7) Steps to Reproduce: 1. get a bare metal host with UEFI fw 2. generate a new host record in satellite and choose GRUB2 HTTP UEFI pxe loader 3. attempt to use httpboot on the host. Actual results: GRUB seems to be downloaded, but fails to be loaded.
