The following table describes known issues in this release and possible workarounds.
Internal Ref. | Bugzilla Ref. | Description |
2482177 | - | Description: RDMA device name for VFs may change after resetting all VFs at once. |
Workaround: Either reset interfaces one by one with a delay in between, or use a network interface naming scheme with predictable interface names, such as NAME_PCI or NAME_GUID: copy /lib/udev/rules.d/60-rdma-persistent-naming.rules to /etc/udev/rules.d/ and edit the last line accordingly. Note that this will change interface names. | ||
- | - | Description: RPM package kernel-modules-extra is required for supporting various OVS Hardware Offloads. To use OVS Hardware Offloads, make sure to install the kernel-modules-extra RPM package which provides various kernel modules that are required for supporting this functionality. |
2345747 | 1890261 | Description: RHEL installer fails to start when InfiniBand network interfaces are configured using installer boot options. |
Workaround: Create a new installation media including the updated Anaconda and NetworkManager packages, using the Lorax tool. For more information on how to do so, please see this page. | ||

1816660 | Description: When the NUM_OF_VFS parameter configured in the Firmware (using the mstconfig tool) is higher than 64, VF LAG mode will not be supported while deploying OVS offload. | |

Workaround: Unbind or detach VFs before you perform these actions as follows.
