Description of problem:

After upgrading Red Hat Satellite from version 6.17 to 6.18, issues are observed with RHEL 7 provisioning.

Provisioning new RHEL 7 systems via PXE/TFTP on EFI-based systems no longer works. The system becomes stuck on the “Booting 'Kickstart default PXEGrub2'” screen immediately after the GRUB menu.

Is this issue a regression from an earlier version:

Yes.

• The issue starts occurring after upgrading Satellite to version 6.18.

• On Satellite 6.17, RHEL 7 provisioning using the same method works without any issues.

Steps to Reproduce:

• Upgrade Satellite and Capsule from version 6.17 to 6.18.

• Attempt to provision a RHEL 7 client system using PXE/TFTP on an EFI-based machine.

Actual behavior:

• RHEL 7 provisioning fails after upgrading Satellite to 6.18.

• During PXE boot on EFI systems, the machine hangs at the “Booting 'Kickstart default PXEGrub2'” screen after the GRUB menu.

• Provisioning does not proceed beyond this point.

Workaround:

Replacing the grubx64.efi file on the Capsule at:

~~~

/var/lib/tftpboot/grub2/

~~~

• with the same file from an existing working system (RHEL 7 or RHEL 8) allows provisioning to succeed.

• However, this workaround is not persistent and may be reverted after running satellite-installer.

Expected behavior:

RHEL 7 provisioning via PXE/TFTP on EFI systems should complete successfully after upgrading Satellite to version 6.18.

Business Impact / Additional info:{}

• The issue is encountered during testing in a development environment prior to performing the upgrade in production.

• This regression may block or delay production upgrades for environments that still require RHEL 7 provisioning.
