Using the same pktgen script (i.e with clone=0) I see that a veth-->bridge-->veth configuration gives about 400K PPS forwarding performance where

Hi I am trying to install xen (64bit) on a Dell PowerEdge 2900. The installation process was something like the following: ----- apt-get install iproute bridge-utils python-twisted binutils zlib1g-dev python-dev transfig bzip2 screen ssh debootstrap libcurl3-dev libncurses5-dev x-dev build-essential gettext python-pyopenssl python-pam python-xml latex tetex-extra tetex-base

Hi, I am using Xen 4.1.1 with Linux 3.0.1 kernel. Previously (Xen 3.4.4 and linux kernel 2.6.18) Xen by default created veth0 <--> vif0.0 pair in dom0. With Xen 4.1.1 these pairs are missing in dom0. Using command ''ip link add type veth'' I can create veth0 and veth1 but vif0.0 is still missing in dom0. (When new domU created I can see vif1.x created) Could you please help

Hi, I am using the latest unstable and when I boot my xen, I do not see any veth devices. This happens even after I start xend. Xend gives this message on a "xend start" SIOCSIFNAME : Device or resource busy Presumably the creation of veth and peth is failing because of this. Any suggestions -Padma _______________________________________________

Hi all ! It seems, that new kernel 2.6.24 offers new feature, that enables me to create pair of virtual Ethernet devices and connect them to each other. This module is called "VETH". However, I have not found any userspace app to use this feature. Please help ! -- -Alexey Eremenko "Technologov"

Hello, I have some problem with poor network performance on libvirt with qemu and openvswitch. I’m using libvirt 1.3.1, qemu 2.5 and openvswitch 2.6.0 on Ubuntu 16.04 currently. My connection diagram looks like below: +---------------------------+ +---------------------------+

Hello, I have no queue configured on tap and veth devices, quest type is of course KVM and I’m using virtio model for VM’s NIC. What we found is that on Xenial (where performance is poor) during test ovs-vswitchd process is using 100% CPU and there are some messages in ovs logs: 2017-05-12T14:22:04.351Z|00125|poll_loop|INFO|wakeup due to [POLLIN] on fd 149

Thanks Cole. I need to use network type="ethernet" with LXC instead of Qemu. I have reopened my bug.
