From your local computer, reboot your instance using the Amazon EC2 console or one of the following commands: To check whether an instance has the enhanced networking sriovNetSupport attribute set, use one of the following commands:. If another instance boots with this file, the operating system will be unable to find the device and eth0 might fail, causing boot issues. To enable enhanced networking instance store—backed instances. Post as a guest Name.

Download the source for the ixgbevf module on your instance from Sourceforge at https: Enhanced networking with the Intel VF interface is enabled if the ixgbevf module is installed on your instance and the sriovNetSupport attribute is set.
All hardware requirements listed apply to use with Linux.
All other operations are supported under Windows. Sign In to the Console. Use the following command to verify that the module is being used on a particular interface, substituting linyx interface name that you wish to check. If another instance boots with this file, the operating system will be unable to find the device and eth0 might fail, causing boot issues.
This file contains the MAC address for the Ethernet adapter of the original instance. Related topics Network Connectivity: Connect to your instance again and verify that the ixgbevf module is installed and at the minimum recommended version using the modinfo ixgbevf command from Testing Whether Enhanced Networking is Enabled.
Systems that use systemd or udev versions or greater can rename Ethernet devices and they do not guarantee that a single network interface will be named eth0. This file is regenerated at the next boot cycle, and any instances launched from the AMI create their own version of the file. The following procedure provides the general steps for compiling the ixgbevf module on an Ubuntu instance.
Is it possible without rebooting?

Active direct attach cables are not supported. The MSI-X interrupts in Linux as of the time this document is written are assigned randomly which means that each queue will deliver packets to a random core. Setting this attribute without the proper 82959 or module version can also make your instance unreachable. If you compile the ixgbevf module for your current kernel and then upgrade your kernel without rebuilding the driver for the new kernel, your system might revert to the distribution-specific ixgbevf module at the next reboot, which could make your system unreachable if the distribution-specific version is incompatible with enhanced networking.
Not all modules are applicable to all devices. For more information, see Accessing Amazon EC2. Sign up or log in Sign up using Google. Optional Connect to your instance and verify that the module is installed. Sign up using Email and Password. If the attribute isn’t set, SriovNetSupport is empty; otherwise, it is set as follows:. If you are using a single interface defaultit will be eth0. From your local computer, enable the enhanced networking attribute using one of the following commands:.
Follow the previous procedure until the step where you stop the instance. Developing efficient networking applications in Linux is not a straight forward task and requires a fair amount of understanding of the hardware and the network stack.
