vnetX interface name persistence
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

How to manually add a new interface to a bridge device?
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:

Network inoperable with QEMU arm example image
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

Right, so your VMs are on the same bridge group now (at Layer2 of OSI).

from vmdk to kvm
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.

How to manually add a new interface to a bridge device?
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..

OpenVswitch with KVM virtual machines
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

How to manually add a new interface to a bridge device?
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:

KVM integrated network (user mode) dying after inactivity
-----BEGIN PGP SIGNED MESSAGE-----

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).

network intermitent, not sure if virtualization issue
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.

Need info on vnet mapping to guests
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
