Virtualization Support

Virtualization makes it possible for one or more operating systems to run simultaneously on the same physical system as virtual machines. This allows you to consolidate several servers onto one system, even if they are running different operating systems. Intel® Network Adapters work with, and within, virtual machines with their standard drivers and software.

See the following subsections for more information.

Note:
  • Some virtualization options are not available on some adapter/operating system combinations.

  • The jumbo frame setting inside a virtual machine must be the same, or lower than, the setting on the physical port.

  • When you attach a Virtual Machine to a tenant overlay network through the Virtual NIC ports on a Virtual Switch, the encapsulation headers increase the Maximum Transmission Unit (MTU) size on the virtual port. The Encapsulation Overhead feature automatically adjusts the physical port’s MTU size to compensate for this increase.

  • In Microsoft Windows Server* 2022 and later, the number of virtual functions (VFs) that the Windows driver advertises to the host may differ from the number of VFs advertised in PCIe configuration space, due to a limitation of hardware resources such as receive queue resources.
