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

Maybe my google-fu is failing me, but I have spent the past couple hours looking at how to add a vnet? Device to my KVM host running CentOS 6, and for the life of me I can't get this going. >From all my research if I want to add a device I should just do 'brctl addif br1 vnet14' if I want to add a vnet14 to bridge br1. When I do this, I get: # brctl addif br0 vnet14

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

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

Can i assign static vnet* device for some guests?

Tried that as well, but this has to be something that gets set at the OS level and loaded, as if you look at dmesg output, you can see all the vnet?? nodes as the OS comes online. So the question is, what is virt-install doing that creates the needed vnet interface that is part of the bridge. I really had to kill and reload the VM just to load a second interface.. --- Howard Leadmon

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 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:

How do you decide what MAC address to use for that VM interface? As I just tried to change the MAC to some other value close, like I made '52:54:00:34:e1:21' into say '52:54:00:34:e1:32', and when I try and load it in, I get the following: error: XML error: Attempted double use of PCI Address '0:0:4.0' Here is one of my network entries: <interface

-----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

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

I have a computer I am using to host a virtual machine. Centos 6, for both, 64 bit. The host machine's network connection seems fine. No problems. Trying to access the virtual machine is usually fine. but then, poof, ssh, http, ftp, all lose connection for about a minute. Then they come back up. I looked in all the logs on both machines, could find nothing, but not sure where to look. My

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
