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

I've run into a problem on my KVM host where a single guest will be unreachable to other guests on the same host. This host has 2 bridged devices and guests assigned to each have the same issue. I've noticed that when I can't reach the problematic guest, the ARP entry for that system is incorrect. This issue seems to only be a problem about 75% of the time when making connections

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

I am running Fedora 16 64bit and installed libvirt. I have the VM running with arm emulation with this one issue I can't figure out. I used Virtual Machine Manager to manage the VM and can access its console there. The Ethernet appears to be eth1 and the guest can set an IP on it etc. However, I cannot see any traffic from the Host when dumping any of the interfaces. I've tried

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

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:

Hi list! I would like to modernize my server at home which is still running Shorewall 3. The server will be running CentOS 6.2 but i also want to use KVM virtualization to run a Windows host on the same box that i can log in to remotely. I looked through the documentation samples on the shorewall site and found several bridging configurations but they do not match my setup, yes it will

Greetings, I'm attempting to get several virtual machines setup on a Fedora19 host system, with the traditional bridge network devices (br0, br1, etc). I've done this many times before with older versions of Fedora (16, 14, etc), and it just works. However, for reasons that I cannot figure out, the bridge doesn't seem to be working in Fedora19. While I can successfully connect to

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. #

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi list, I searched the web for bug reports regarding this phenomenon I see on *multiple* machines of a customer, however, I didn't find an exact fit. So, I'd like to ask here whether anyone else has run into this. I have multiple CentOS 6 machines running using KVM to virtualize a bunch of machines on them (LVM-based). Software releases

I just wrote this to assist some Red Hat folks understanding what libvirt does with iptables, and thought it is useful info for the whole libvirt community. When I have time I'll adjust this content so that it can fit into the website in relevant pages/places.

I need some help in understanding libvirt's virtual networking. I have configured bridged networking (shared physical device) on libvirt+KVM system which is working fine. Also, I am using default NAT network on with virbr0 bridge device and virbr0-nic. I would like to get better understanding on virbr0-nic works in this virtual network configuration. I understand that traffic from virbr0

I encounter a problem about the network when using virt-manager to create and run a VM. when I want to establish a network bridge for the guest OS, I generally use two kinds of ways described as fellow : First method : create a bridge with the help of linux commad: brctl, or Second method : using

Hi We have the following situation: A hypervisor using KVM-Qemu/libvirt with a single VM. The VM has the internal IP 192.168.122.151 on the default network pool using virbr0 on the hypervisor. We've set up netfilter rules to DNAT requests on one IP of the hypervisor to the VM. So, first of all, forwarding to the internal IP range is allowed: > $IPTABLES -I FORWARD -m state -d
