Description of problem:

During provisioning of a RHEL 8 host on a libvirt compute resource, the VM fails to boot into the installer. The VM immediately drops into the UEFI PXE boot screen and repeatedly times out with the following error:

```
>>Start PXE over IPv4.
   PXE-E18: Server response timeout.
BdsDxe: failed to load Boot0002 "UEFI PXEv4 (MAC:5254006F6DCB)" ...
IPv4(0.0.0.0:0, DHCP:0.0.0.0) : Not Found

```
How reproducible:

Always

Is this issue a regression from an earlier version:

Yes, Rhel 7,9 and 10 works

Steps to Reproduce:

1. Configure Satellite for PXE provisioning
2.  Set up RHEL 8 content
3. Create provisioning hostgroup
4. Configure SecureBoo
5. Create Libvirt Compute Resource
6. Create Host
7. Verify VM creation on Libvirt
8. Wait for build completion

Actual behavior:
Build status is pending and when checked on Libvirt it did not start booting in the first place. (Booted for Rhel 9 and 10 )

Expected behavior:

Build status reaches "Installed" state within timeout period

Business Impact / Additional info:

RHEL 8 hosts cannot be provisioned on libvirt, blocking automation and QA workflows.
Verified that networking, DHCP, and TFTP services are operational; issue appears specific to RHEL 8 bootloader delivery.
