Doc Text:
Previously, after a successful upgrade of a Red Hat Enterprise Virtualization Hypervisor node installed on EFI, the grub boot menu only contained an entry to boot the updated kernel. It was not possible to roll back in the event of a bad install or some other incompatibility with a new build. Now, a fall-back option is left in the grub menu in case the previous kernel is required.

Description of problem:
In fact, rhev-h used the /EFI/redhat/grub.conf in /dev/mapper/36782bcb03cdfa200174636ff055184dcp1 to boot rhev-h under uefi mode.
But when upgrade rhev-h via rhevm in uefi mode,the /EFI/redhat/grub.conf missed backup version

No this issue when upgrade rhev-h via tui/cmdline in uefi mode

Version-Release number of selected component (if applicable):
rhev-hypervisor6-6.4-20130116.3

How reproducible:
100%

Steps to Reproduce:
1.install the rhev-hypervisor6-6.4-20130116.3 in uefi mode.
2.upgrade the rhev-h via rhevm in uefi mode.

Actual result:
After upgrade rhev-h from rhev-hypervisor6-6.4-20130116.3 to rhev-hypervisor6-6.4-20130116.3 via rhevm in uefi mode.
we only selected the new version to boot,the /EFI/redhat/grub.conf missed the backup version part

[root@localhost admin]# mount /dev/mapper/1ATA_SAMSUNG_HD322GM_S2PAJ90B519911p1 /mnt
[root@localhost admin]# cat /mnt/EFI/redhat/grub.conf

    initrd /initrd0.img
    [root@localhost admin]# 

Expect result:
The /EFI/redhat/grub.conf could save the backup version part when upgrade rhev-h via rhevm in uefi mode
Comment 18 haiyang,dong 2013-02-01 02:37:33 UTC 
Test version:
rhev-hypervisor6-6.4-20130130.0.0.el6
ovirt-node-2.5.0-17.el6.noarch

After upgrade success and reboot, there two version can be selected to boot, also enter the latest version, check that 
[root@localhost admin]# mount /dev/mapper/1ATA_SAMSUNG_HD322GM_S2PAJ90B519911p1 /mnt
[root@localhost admin]# cat /mnt/EFI/redhat/grub.conf
