similar to: KVM - Network bridge issue - lots of overruns

Hi, Over the past few days I've been trying to get a prototype working of a stateful firewall for a Virtual Machine using Libvirt's network filters. My goal is to replace the current custom Python/Java code in the Apache CloudStack [0] project by Network Filters of Libvirt. Both IPv4 and IPv6 should work, but I started off with IPv4 and I have issues with accepting back

I am running NOX controller with a python script that prints out the destination mac and the source mac for each packet arriving at the now controller and then floods it out. So here's what happening: With em1 connected, all the packets that arrive at em1 are coming to the controller and printing out the details. However, without em1 connected to the OVS, when I have the following setup:

Hey, I have KVM installed on my Fedora 17 box. I added the network interfaces of the virtual machines to the openvswitch bridge as follows: ____ ____ / VM1\______br0_______/ em1\ \____/ | \____/ | _|_ /VM2\ \____/ virbr0 is the virtual network switch VM1 and VM2 are on the same subnet having tap interfaces vnet0 and vnet1 respectively. em1 is the default

Hi, I have tried the qemu-ifup script as below with nmcli command as brctl is deprecated on rhel8, but the guest network can not work. I think the script needs update. Could you please help to have a look? Thank you in advance. 1. prepare a linux bridge on the host named br0; 2. prepare the qemu-ifup script as below: # cat /etc/qemu-ifup #!/bin/bash # A br0 bridge should be already set up. #

Hello, I'am trying to efi-netboot a HP ProLiant DL120 Gen9[1], that has multiple NICs, one embedded 2-port and an extra 4-port, so I got to the HP/EFI/multinic problem. I read through the multinic mailthreads and using current master[2], it booted successfully to syslinux but then another problem manifested: Syslinux for some reason asks the gateway and not next-server about ldlinux.e64 (I

Hi, I would like to run a network firewall as a VM on a KVM host. There are ~ 25 VLANs delivered to the KVM host on three dedicated links, no LACP or other things. I have the VLANs 100-180 on the host's enp1s0, the VLANs 200-280 on the host's enp2s0 and the VLANs 300-380 on the host's enp3s0. To save myself from configuring all VLANs on the KVM host, I'd like to hand the entire

I used openvswitch with virt-intall I defined a network <network> <name>private</name> <bridge name='virbr0'/> <forward mode='bridge'/> <virtualport type='openvswitch'/> </network> But get no ip for the ovs port when I launch the instance. Is this correct? ci-info:

Hi All, I'm trying to identify a new server as a replacement for what our customer actually has (DELL PowerEdge 860). The server will mount the Digium board TE121, we already have, with echo cancel onboard. I need to know if someone could suggest a new server that's compatible with this board. With "compatible" I mean that's not having any problem like IRQ sharing, IRQ miss

Hello: I have a host running two KVM guests. The guests use br0 and each has a static IP address. I am trying to figure out if there is a way to use snmpd on the host to measure the traffic usage of the guests. I do not want to require anything running on the guests since I do not control them. Looking at netstat -in on the host, I see this info: Kernel Interface table Iface MTU Met

I am running KVM virtualization with libvirtd (libvirt) 0.10.2 in bridged network mode, however I still have the default virtual network bridge/interfaces and dnsmasq on the host. What I am trying to understand is whether or not dnsmasq and the virtual network (*virbr0, Vnet0 and Vnet1*) still play any role. If not, can I remove them? On most virtual hosts I see they are left around even when a

Hi Folks, I'm trying to auto-create a VM using a kickstart server and gPXE with my VMs. The underlying physical host is CentOS 6.0 running libvirt-0.8.1-27, and libvirt-python 0.8.1-27, virt-manager 0.8.4-8. The underlying network config on the physical host is: # ip -o -4 addr show 1: lo inet 127.0.0.1/8 scope host lo 6: vnet0 inet 10.8.31.61/23 brd 10.8.31.255 scope global vnet0 7:

G'day, I have a host running two kvm guests. One of them gets very poor network performance, testing with iperf I get ~10MBit/sec to guest A, >400MBit/sec to guest B (running iperf between the host/guest). Both guests are using the same bridge: Guest A: <interface type='bridge'> <mac address='54:52:00:75:24:91'/> <source
