Hi I''m testing around with xen 3.0 snapshot from last week. And i''m now having a problem with a xenbr which is based on a vlan if (dot1q). this is all in dom0 os: debian testing network: tg3 I can start the bridge based on my normal physical eth0 which is working without any problems. My clan without bridge is also working. I can start the bridge based on a vlan if with help

Hello, Despite of reading a lot of descriptions I don''t understand the network configuration. I simply have too little experience. I work remote with the machine via ssh. My dom0 is running. I copied an existing installation into a LV and created the following file: # cat /etc/xen/domu-sarge # -*- mode: python; -*- kernel = "/boot/vmlinuz-2.6.18-4-xen-686" #kernel =

Hi all, i have a xen 4.3 installation and would like to have a bridge bond szenario: *** eth0 eth1 | | bond0 | br0 | vif = [ ''bridge=br0,mac=xx:xx:xx:xx:xx:xx'' ] *** With the network script in debian wheezy *** /etc/network/interfaces auto bond0 iface bond0 inet manual slaves eth0 eth1

I want to add the following route command route add -net 192.168.2.0/27 gw 192.168.2.3 via the normal network setup. The result should be the following routing table (the first line): 192.168.2.0/27 via 192.168.2.3 dev xenbr1 scope link 192.168.2.0/27 dev eth2 proto kernel scope link src 192.168.2.4 192.168.2.0/27 dev xenbr1 proto kernel scope link src 192.168.2.3 192.168.1.0/24 dev xenbr0

Hi, I'd want to configure persistent static routes, ie in config files, but I can't configure static routes, I tested: [root at centos7 ~]# cat /etc/sysconfig/network-scripts/routes-enp0s3 ADDRESS0=10.10.10.0 NETMASK0=255.255.255.0 GATEWAY0=192.168.1.1 logs says nothing: ago 27 15:38:29 centos7.vhgroup.corp NetworkManager[2299]: <info> Activation (enp0s3) Stage 5 of 5 (IPv4

Dear Friends I have 2 netcards (eth0 to Internet and eth1 to internal network) in CENTOS 4.2, bit when I boot system the up eth0 and et1i [OK]. When I run ifconfig the eth1 has not IP configure, then I run command ifdown eth1 and ifup eth1, after eth1 is work perfect. Below I show file /etc/sysconfig/network-scripts/ifcfg-eth1 # Please read /usr/share/doc/initscripts-*/sysconfig.txt # for

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

The network-bridge script is fragile because of how grep is used. As one example, if I already have "xenbridge", I can''t create "xenbr". (It''s actually worse than that, because it''s even grepping the header output by brctl show.) Assuming dom0 is on Linux with /sys mounted (is that a safe assumption?) we can check for the existence of a bridge, and

Hi, We have configured several xen guest OSes on a server running SLES10. The physical server is a Sun 4200 with 3 NICs installed, configured, and working. Each of the xen guest OSes have three virtual nics, configured for RAC, Interconnect, and public IPs as follows; eth0 - public (routable and registered in DNS) eth1 - private (not routable, uses a seperate network subnet for

Hi list, kernel-xen-2.6.18-53.1.14.el5 and kernel-xen-2.6.18-53.1.19.el5 do not detect/initialize/whatever my eth1 network card any more. With kernel-xen-2.6.18-53.1.13.el5 everything is working as expected. With the two recent kernels I only get an Interface named __tmp786686833 which is not added to xenbr... lspci -v to the adapter in question says 02:00.0 Ethernet controller: Intel

Hello list, Please don''t shoot me. I know I''m doing something with bonding that bonding wasn''t made for. I just want to give it a try. I want a simple mechanism to have a failover on a 24Mbit line to a 2Mbit line in case the 24Mbit line goes down. Between A and B there are two lines: a 24Mbit and a 2Mbit. I use two OpenVPN tunnels with tap devices: +-- tap0 (A)---

took a couple months off due to road blocks, hoping a fresh look would allow me to use my server as desired. I have three ports, eth0-2 over two nics. I want to bond them, and then use a bridge to connect to virtual machines on the virtual host computer. Never having done this, I am confused on some parts. Here is where I am at now and any pointers helpful. Single server, centos 6.x My issue

Hi, We would like to use VLAN tagged packets to be sent/received by the guest VMs running on xen hypervisor. Does xen bridging support vlan tagged packets arriving on the physical nic from outside of the xen host to be passed through with the vlan tag to the vif of the guest with the guest VM receiving the tagged packet ? We have a xenbr configured with two interfaces - eth3 (physical

Greetings all. This has been an ongoing issue for me for a few months, and I''ve been trying to get an answer. My server has two NICs, and I want to set up the following: NICs (x2) -> bond (mode 5) -> Xen Bridge -> Doms ...however, trying to configure this doesn''t seem to work: network-bridge steals eth0 instead of bond0, which breaks the bond AND my networking. The

Hi all, First, i''m french and my english is approximately, thanks to be indulgent. I have 2 Xen server 4.0 on Debian Squeeze with this kernel : 2.6.32-5-xen-amd64.

Hi guys, Greetings for the new year The problem faced by me is simple, I cannot get channel bonding to work perfectly with Xen. I am trying to boost the bandwidth of guest domains by using link aggregation (a.k.a channel bonding). I have tried round robin (mode 0) and high availability (mode 1). I know that mode 1 will not give me bandwidth boost. But strangely once i try mode 1 for the guest, I
