The kernel device driver ibmvnic provides support
for vNIC (virtual Network Interface Controller)
which is a PowerVM virtual networking technology
that delivers enterprise capabilities and simplifies network management
on IBM POWER systems. It is an efficient high-performance technology.
When combined with SR-IOV NIC, it provides bandwidth control
Quality of Service (QoS) capabilities at the virtual NIC level.
vNIC significantly reduces virtualization overhead resulting
in lower latencies and fewer server resources (CPU, memory)
required for network virtualization.
The kernel device driver ibmvnic is supported with SLES as follows:
* ibmvnic is supported with SLES 12 SP3, SLES 12 SP4, SLES 15, SLES 15 SP1, and forward. It is recommended to have the most current SLES kernel maintenance update installed.
* ibmvnic is fully supported on IBM POWER9 systems using the most current POWER9 firmware installed.
* ibmvnic is supported as Technology Preview only on IBM POWER8 systems.
* Attempting an installation of SLES 12 SP3 using an SR-IOV (Single Root I/O Virtualization) vNIC (virtual Network Interface Controller) interface results in unexpected behavior or failure to complete the installation on POWER.
The SLES 12 SP3 installation can be done using an alternative device, such as a virtual ethernet adapter.
After the SLES 12 SP3 installation is complete, a vNIC interface can be configured as normal.
