Re: What's the best way to make use of VLAN interfaces with VMs?
Even more puzzling, I reverted back to the old configuration to confirm what I had seen and found that it works in one direction but not the other: i.e. from 192.168.0.110 to 192.168.0.120, but not the other way around. Must be something with my configuration....which I can follow up on. So, thanks again for your help. Richard On 12/3/19 11:36 AM, Richard Achmatowicz wrote: > Laine >

Hi Laine What you have suggested sounds eminently reasonable. Thanks for your advice. I'm going to give it a shot and report back.

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: # brctl addif br0 vnet14

What's the best way to make use of VLAN interfaces with VMs?
Hello I have a problem with attaching VMs to a VLAN interface. Here is my setup: I have several physical hosts connected by a physical switch.  Each host has two NICs leading to the switch, which have been combined into a team, team0. Each host a has a bridge br1, which has team0 as a slave. So communication between hosts is based on the IP address of bridge br1 on each host. Up until

Hi, I''m setting up my first xen machine, and I''m trying to setup two Virtual Machines, each mapped to a physical adapter on a different network.

changue bridge name, libvirt refuses to take new name
hi all, (this events ocurred before my previous mail about the uuid incident) so, I installed a vm host: rhel6 guest: centos6 network: bridge (br0, eth1 as slave) but then, I changed the name of the bridge from br0 to br1 (because br1<->eth1 seems pretty than br0<->eth1) so: - mv /etc/sysconfig/network-scripts/ifcfg-br0 /etc/sysconfig/network-scripts/ifcfg-br1 - edited

Bug#571634: bridge loosing connection
Hi, I'm not sure but I think I suffer under the same problem with a bit different setup with squeeze testing and xen 4.0rc5. In fact I'm using bridges in the dom0 and the connections to the domU get lost sporadically. In don't see where's a solution to the problem... Is it now a bug? When it's an iptables bug, where's the corresponding bug in the iptables bugtracker

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.. --- Howard Leadmon

Starting libvirtd cuts off host access to external network
I've spent some hours on this without success - any help greatly appreciated. I've just done a new RHEL6 setup, with a KVM guest (first time). The basic installation works fine until I start libvirtd; at this point, the host machine loses access to the external network: step 1: ping from host to network works; external machine on network can ping both eth0 and br1 on the host step

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: error: XML error: Attempted double use of PCI Address '0:0:4.0' Here is one of my network entries: <interface

shorewall6: IP fragementation getting blocked?
Hey, I have a setup that has one machine communicating to a server using UDP over IPv6. For specifics, it is using collectd with a boosted MaxPacketSize in the network config. What this means is there is some IP fragmentation happening, and that is getting REJECTed. My policy is to REJECT, and I have an ALLOW for the particular communication I want. What I''m getting in my logs is

[Bridge] bridge is not forwarding the packet
Hi Rahul, If you're certain that your problem isn't as Stephen suggested, you might want to have a look at this: --- (From http://ebtables.sourceforge.net/brnf-faq.html <http://ebtables.sourceforge.net/brnf-faq.html> ) How do I let vlan-tagged traffic go through a vlan bridge port and the other traffic through a non-vlan bridge port? Suppose eth0 and eth0.15 are ports of br0.

CentOS 6 - VM network bridge issue
I built a CentOS 6 machine to host several CentOS 6 guest servers. As all guests will be Internet facing I set up the host with two bridged NICs and assigned an Internet facing IP address to br0 and a local IP address to br1. Each guest was installed using br0 and br1 with virtio drivers. On each I assigned an Internet facing IP address to eth0 and a local IP address on eth1. So far so good. I
