RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.
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.
