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

Hello, While using xen 4.1-testing.hg (r23202) I noticed that the ''vifname'' config value is not handled by xl, but is handled by xm. Is there a workaround or patch for this? My firewall and scripts depend on static vifnames. XM works good - it adds multiple interfaces to multiple bridges and configures them appropriately. But with xl it differs -- here only tap devices are

Hi folks, sorry for my bad english, but I am not a native speaker. I want to setup a virtual firewall-host in a UML-Session. I''m using Kernel 2.4.27-um1 and shorewall 2.2.2-2 from Debian sarge. I have 4 nic''s in my System: eth0 -> localnet 0 eth1 -> localnet 1 eth2 -> wlan eth3 -> DSL/ppp0 I''m using four bridges br0,br1,br2,br3. The UML firewall host is

I'm looking for some information regarding the interaction of KVM, VLANs, firewalld, and the kernel's forwarding configuration. I would appreciate input especially from anyone already running a similar configuration in production. In short, I'm trying to figure out if a current configuration is inadvertently opening up traffic across network segments. On earlier versions of CentOS

Hi, We have a Dell server with 4 Ethernet interface. I would to aggregate them in a bond. Everything work but the default gateway doesn?t work on the ? bond0 ? interface and I have no links.

hi- i''ve been trying to setup an outgoing queue that prioritizes traffic depending on whether it recognizes the MAC address the packet is destined to -- and i''ve not been having any luck. i think my ebtables rule is correct as the packet count when i do an --Lc is increasing in an expected way, but when i look at the tc statistics, i don''t think the packets are

Dear list, Being a libvirt noob, I have some trouble understanding. It is about getting two different guest in the same network. *********** I've defined a network with libvirt. This is the source xml: <network> <name>private2</name> <uuid>9684f2c6-6fd0-491b-9cb5-80ee268b01ce</uuid> <bridge name='br2' stp='on' delay='0'/>

We just went to replace the bridge/firewall services one one server with the same on another. It's pretty simple, and I literally cloned (w/ rsync) a third server that does this onto the one that will be the new one. Then copied the /etc/sysconfig/iptables from the one being replaced, and brought it up this morning. Nope. We had to put everything back the way it was. The new one sees the two

Hello, I?m trying to configure a CentOS 7 server to act as a host for a bunch of virtual servers (KVM). I have an 802.3ad bonded Ethernet connected to the server with a bunch of tagged VLANs. I want to be able to build a bridge interface on the server for each VLAN and then attach that to the bond interface and the virtual clients. I also want to attach a host interface to one of the VLANs

Hi all, I have one bridge system (used for controlling bandwidth) connected to three different DSL ISP provider. I have the following setup below: - +-------------+ | br0 | | -> eth1 | -> DSL_1 | -> eth2 | +-------------+ | br1 | | -> eth3 | -> DSL_2 | -> eth4 | +-------------+ | br2 | | -> eth5

Running CentOS 5.4 x64. Have successfully bridged eth2 with br2 by following the instructions here: http://wiki.libvirt.org/page/Networking (under the RHEL section) Have been running several KVM VMs successfully via this bridge. I am now trying to bridge additional interfaces by using the same routine. Each bridge is named to correspond with the ethX device its bridged with. Example of

A number of weeks ago I had huge help from many of you configuring routing on a server with multiple Internet facing nics. Thanks for all of your help!!!! I am still having a routing issue that I am hoping someone can help me tweek. This server, besides acting as our gateway to the internet, is also our web and email server. The server has 4 nics. Two are connected to the internet and the

Hello everybody!

A CentOS 6.3 box ("host") runs several KVM virtual machines, each of which has two interfaces attached to the two bridges br1 and br2 (and each thus has two IP's; one on 192.168.0.0/22 and one on 192.168.4.0/22); net.ipv4.ip_forward on the host is 1. Simplified diagram: host +---------------+ |

One of the primary benefits of virtualization and other containers is isolating the applications you run from the base OS. Putting services other
