Prior to this update, the Advanced Host Controller Interface (AHCI) driver was not included in the initrd.img file. As a consequence, a Red Hat Enterprise Linux 5 guest in some cases failed to boot on a Red Hat Enterprise Linux 7 hypervisor. With this update, installing Red Hat Enterprise Linux 5 as a guest now always includes the AHCI driver, and the guest is therefore able to boot as expected.

Tested with the latest RHEL 5.11 tree * Install 5.11 as KVM guest on latest RHEL 7 nightly hypervisor: Results: - both ahci.ko and virtio_blk.ko are included in the initrd - virt-manager uses virtio by default - after stopping the VM, changing the default disk bus from virtio to IDE and restarting: the VM was able to boot, disk is now /dev/hda instead of /dev/vda * Install 5.11 as KVM guest on latest RHEL 5.11 nightly hypervisor Results: - both ahci.ko and virtio_blk.ko are included in the initrd - virt-manager uses virtio by default Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
