Can reproduce: Steps to Reproduce: 1. Install rhvh-4.3.0.5-0.20190409.0 on EFI host 2. Install hotfix kernel with "yum install kernel-3.10.0-957.29.1.el7.x86_64.rpm" and reboot 3. Upgrade to redhat-virtualization-host-image-update-4.3.4-20190620.3.el7_6 and reboot Actual results: Fails to boot, and in the emergency shell: # nodectl check Status: FAILED Bootloader ... FAILED - It looks like there are no valid bootloader entries. Please ensure this is fixed before rebooting. Layer boot entries ... FAILED - No bootloader entries which point to imgbased layers Steps to Reproduce: 1. Install rhvh-4.3.0.5-0.20190409.0 on EFI host 2. Install hotfix kernel with "yum install kernel-3.10.0-957.29.1.el7.x86_64.rpm" and reboot 3.

The host rebooted fine and in the new kernel. Then, it was upgraded to rhvh-4.3.0.8-0.20190610.0, but the boot fails. There is only two options in grub, none of them the hotfix kernel. rhvh-4.3.0.8-0.20190610.0 rhvh-4.3.0.5-0.20190409.0 Version-Release number of selected component (if applicable): imgbased-1.1.7-0.1.el7ev.noarch redhat-release-virtualization-host-4.3-0.5.el7.x86_64 How reproducible: Always Steps to Reproduce: 1.

That's unexpected, a second reboot leads to booting the old kernel. After upgrading the rhvh image, the system fails to boot, stopping at the emergency shell. If Booting back into the old image, the hotfix kernel is lost. Additional info:
