OLVM: Fails to Create/Delete/Modify Bond Interfaces with UEKR7 Kernel lower than "5.15.0-" (Doc ID 2975009.1)

Last updated on MAY 22, 2024

Applies to:

Linux OS - Version Oracle Linux 8.8 with Unbreakable Enterprise Kernel [5.15.0] and later
Information in this document applies to any platform.


With the UEK R7 kernel "5.15.0- through 5.15.0-202.135.2" on the KVM hosts, all network configurations related to a bond interface fail through OLVM Manager UI.
Operations like creation of bond interface, addition of vlan or logical network to a bond interface, removal of an interface etc fails.

For new installations, addition of KVM hosts and deployment of self hosted engine fails if the management network  is configured on a bond interface.

Below events are reported in the OLVM Manager UI. Note that the errors can differ and are related to the tasks that you perform. Please refer to the cause section to match the exact error events related to this issue.
