After upgrading the hypervisor on a legacy (non-EFI) machine, the /liveos directory was unmounted, so users could not access the backed up version of the hypervisor. Now, a non-EFI installation reads grub.conf for changes before it unmounts the /liveos directory, so the hypervisor backups are still available after upgrade.
Description of problem:
The grub miss the backup version after upgrade in legacy(non-uefi) machines.
e.g.
1. upgrade form rhev-hypervisor6-6.4-20130130.0.0.el6 to itself.
2. upgrade from rhev-hypervisor6-6.3-20121120.0.el6_3 to rhev-hypervisor6-6.4-20130130.0.0.el6
Version-Release number of selected component (if applicable):
rhev-hypervisor6-6.4-20130130.0.0.el6
How reproducible:
100%
Steps to Reproduce:
1. Install rhev-hypervisor6-6.3-20121120.0.el6_3 to legacy machine.
2. Upgrade rhevh to latest version via tui / cmd / rhevm.
3. focus on grub.
Actual results:
1. The grub miss the backup version after upgrade in legacy(non-uefi) machines.
2. No such issue in UEFI machine.
Expected results:
Gurb can save the backup version part after upgrade.
Additional info:
rhev-hypervisor6-6.5-20131017.0
ovirt-node-3.0.1-4.el6.noarch
Gurb can save the backup version part after upgrade.
Enter the backup version can successful.
