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. #

Hi, I try to add 2 VF functions to VM via network. Livirt networks: vnet0: <network> <name>vnet0</name> <forward mode='hostdev' managed='yes'> <pf dev='eth0'/> </forward> </network> vnet1: <network> <name>vnet0</name> <forward mode='hostdev' managed='yes'> <pf

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

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 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

Hi all, How can I see what vnet is attached to a certain kvm guest?? For example: I have a kvmguest1. When I launch this guest with virsh command, virsh creates a new vnetX interface for this guest. How can I extract this virtual net interface (vnet0, vnet1, vnet2 or so on) using a script?? Thanks. -- CL Martinez carlopmart {at} gmail {d0t} com

Hi, I have a fedora22 host and trying to use virt-install to install a fedora22 guest. The host is configured with bridge networking, using eth0 as its local interface. It appears the guest is communicating on vnet0 instead of eth0, so it can never reach the outside to download the install files. Where is vnet0 configured? Is it set by default when a bridge is created? I have one other guest on

Hello all, I was reading http://www.etherboot.org/wiki/appnotes/autobootchainurl, and figured that as long as I was going to be modifying the code I might as well try a cleaner solution. ?Attached to this message is a patch that makes the following changes: 1) Allow the "dhcp" command to accept a list of interfaces and to try them in order until it succeeds, e.g.: ?gPXE> dhcp net0

Hi, I will try to explain my case, I hope this is rigth place to do it. My goal is migrate an Ubuntu 9.10 64bit VMWare VM from a Win2k8 64bit server to an Ubuntu 9.10 64bit server. Following some tutorials I've got a .qcow2 file from .vmdk and a .xml file from .vmx file Running virsh define/start all was fine, but VM is unaccessible: no ping, no ssh, also from hosting server. This is

Hi! I'm aware that (host side) vnetX are created when VM boots. But I'm trying to figure out a way ti create a persistence in vnetX names. What I mean is, say, I want to associate VMs vm0 to vnet0, vm1 to vnet1, vm2 to vnet2 and so forth, no matter which order the VMs are booted. I looked around network XML format, but did't find something... Since I'm using Open vSwitch as

I have centos 6 running kvm. IPv4 works perfectly works.

-----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
