This patch adds experimental VMDq support (AKA Netchannel2 vmq) to the ixgbe driver. This applies to the Netchannel2 tree, and should NOT be applied to the "normal" development tree. To enable VMDq functionality, load the driver with the command-line parameter VMDQ=<num queues>, as in: $ modprobe ixgbe VMDQ=8 Yo...

The addition of VMDq support to ixgbe completely broke normal RSS receive operation. Since RSS is the default operating mode, the driver would cause a kernel panic as soon as the interface was opened. This patch fixes the problem by correctly checking the VMDQ_ENABLED flag before attempting any VMDQ-specific call. S...

The correct kernel configuration for VMDq support is CONFIG_XEN_NETDEV2_VMQ, not CONFIG_XEN_NETDEV2_BACKEND.

Hello, Did 3.4 come with vmdq, sr-iov, etc.. (netchannel2) support included? If so, is there any documentation available on how to make use of it? Also, these techniques seem like a good way to improve network performance on hardware that supports it, but for folks that want to use iptables and other network management utiliti...

Hello, Is there a HowTo or tutorial about the configuration of VMDq or SR-IOV with XEN? Thanks in advance.

Hi, all: Does xen 4.1 & kernel 3.4 support intel VMDq? How can i make our domU benefit from this? -- 高永超 (flex) 运维工程师 Douban Inc.

The attached patches add vmq (multi-queue) support for netchannel2. (also known as VMDq) These patches were based on a previous implementation written for netchannel1 by Kaushik Kumar Ram. These patches are based on the latest netchannel2 public trees. Patches 1 and 2 are for the Xen tree and patches 3 and 4 for the linux tree. This version provides the basic multi-queue functionali...

What it is: vhost net is a character device that can be used to reduce the number of system calls involved in virtio networking. Existing virtio net code is used in the guest without modification. There's similarity with vringfd, with some differences and reduced scope - uses eventfd for signalling - structures can be moved around in memory at any time (good for migration) - support memory

Guys, I''ve successfully ran dom0/domU (both Debian) in my local laptop using 2.6.32.15 dom0 with xen-4.0.1-rc3-pre. Great. Now I want to install it into couple of test-machines without compiling from source. So I did following.. a. make dist-xen b. make dist-tools PYTHON_PREFIX_ARG="--install-layout=deb" c. make dist-stubdom This
