In our internal build of RHV-H 4.4 grub2-efi-ia32-2.02-76.el8.x86_64 is included in RHV-H-4 4.4/el8 instead of grub2-efi-x64-*. Upstream oVirt Node looks correctly including grub2-efi-x64.
Test version: redhat-virtualization-host-4.4.0-20191204.2.el8_1 grub2-efi-x64-2.02-78.el8_1.1 RHVH 4.4 correctly including grub2-efi-x64. So the bug is fixed, change bug status to VERIFIED.
