4.4. NetKVM driver parameters

Logging.Enable

A Boolean value that determines whether logging is enabled. The default value is Enabled.

Logging.Level

An integer that defines the logging level. As the integer increases, so does the verbosity of the log.

Assign MAC

A string that defines the locally-administered MAC address for the paravirtualized NIC. This is not set by default.

Init.Do802.1PQ

A Boolean value that enables Priority/VLAN tag population and removal support. The default value is Enabled.

Init.MaxTxBuffers

An integer that represents the number of TX ring descriptors that will be allocated. The value is limited by the size of Tx queue of QEMU.

The default value is 1024.

Valid values are: 16, 32, 64, 128, 256, 512, and 1024.

Init.MaxRxBuffers

An integer that represents the number of RX ring descriptors that will be allocated. The value is limited by the size of Tx queue of QEMU.

The default value is 1024.

Valid values are: 16, 32, 64, 128, 256, 512, 1024, 2048, and 4096.

Offload.Tx.Checksum

Specifies the TX checksum offloading capability.

In Red Hat Enterprise Linux 10, the valid values for this parameter are:

Offload.Rx.Checksum

Specifies the RX checksum offloading capability.

In Red Hat Enterprise Linux 10, the valid values for this parameter are:

Offload.Tx.LSO

Specifies the TX large segments offloading (LSO) capability.

In Red Hat Enterprise Linux 10, the valid values for this parameter are:

MinRxBufferPercent

Specifies minimal amount of available buffers in RX queue in percent of total amount of RX buffers. If the actual number of available buffers is lower than that value, the NetKVM driver indicates low resources condition to the operating system (requesting it to return the RX buffers as soon as possible)

Minimum value (default) - 0, meaning the driver never indicates low resources condition.

Maximum value - 100, meaning the driver indicates low resources condition all the time.
