B.2. How to Set Up Red Hat Virtualization Manager to Use Ethtool
You can configure ethtool properties for host network interface cards from the Administration Portal. The ethtool_opts key is not available by default and needs to be added to the Manager using the engine configuration tool. You also need to install the required VDSM hook package on the hosts.
Adding the ethtool_opts Key to the Manager
On the Manager, run the following command to add the key:
# engine-config -s UserDefinedNetworkCustomProperties=ethtool_opts=.* --cver=4.0
# systemctl restart ovirt-engine.service
On the hosts that you want to configure ethtool properties, install the VDSM hook package. The package is available by default on Red Hat Virtualization Host but needs to be installed on Red Hat Enterprise Linux hosts.
# yum install vdsm-hook-ethtool-options
The ethtool_opts key is now available in the Administration Portal. See Section 9.4.2, “Editing Host Network Interfaces and Assigning Logical Networks to Hosts” to apply ethtool properties to logical networks.
