The CVE-2018-10873 issue was discovered by Frediano Ziglio (Red Hat).
Bug Fix(es) :
* When upgrading Red Hat Virtualization Host (RHVH), imgbased fails to run garbage collection on previous layers, so new logical volumes are removed, and the boot entry points to a logical volume that was removed.
If the RHVH upgrade finishes successfully, the hypervisor boots successfully, even if garbage collection fails. (BZ#1632058)
* During the upgrade process, when lvremove runs garbage collection, it prompts for user confirmation, causing the upgrade process to fail.
Now the process uses 'lvremove --force' when trying to remove logical volumes and does not fail even if garbage collection fails, and as a result, the upgrade process finishes successfully. (BZ#1632585)
