similar to: Routing network daemon to xenbr1

I am not quite sure if this issue relates to iptables, routing or Xen virtual machines. Too many variables for my simple mind, so I'm asking some advice :) This is my network setup: Internet --- eth2 + CentOS dom0 / firewall / router + eth1 (xenbr1) --- LAN with private IPs --- separate file server and workstations + eth0 (xenbr0)

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

As I received no response on the general CentOS list, I'll repost it here as the question is about Xen virtual machine routing. This is my network setup: http://pastebin.com/kyWpTQYU Lets assume my dom0's eth2 public ip is 1.2.3.33 and my dmz network 11.22.33.96/255.255.255.224 . I have created NAT from my LAN with iptables. You can see my /etc/sysconfig/iptables here:

Dear Xen users, I was wondering if there is a way to change the xen bridge (vif) of a running domain. For example, if I have booted a domU with xenbr1 as vif. Now is it possible to change the vif to xenbr2 while the domU is running? If yes, then can someone guide me a little so as to where to start looking?

Hello folks, I have this really strange routing problem that no amount of googling and experimenting has been able to solve. Then again, I''m new to Xen and "advanced" networking, so I could be missing something very basic. Summary: an unprivileged domU with PCI frontend for a NIC is used as a router; icmp gets routed, but tcp/ip only partially. I''m using a

Dear I need create second bridge xenbr1 for separate traffic between my virtual machine , I following this step but show message that Link veth0 is missing, how I can create veth0 ? When I run script for create xenbr1 ./network-bridge netdev=eth1 bridge=xenbr1 start Shwo this message Link veth0 is missing. This may be because you have reached the limit of the number of interfaces that the

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

Hello, I''m new to Xen (and this mailing-list) and facing some problems with the network. I''m stuck and don''t know how to continue. And Google isn''t very helpful either... My setup: - Ubuntu 7.10 for dom0 and Debian 4.0 for all domU - 4 physical NIC (DHCP from my ISP, internal LAN, DMZ & WLAN) - 1 Dom as firewall/router - 1 domU with internal services

I am attempting to create an IDS appliance proof-of-concept using Xen to virtualize the management server and sensors. To keep things simple, I am just trying to get one domU sensor and the domU management VM working together for now, but plan on using multiple domU sensors eventually. The VMs are all configured and ready to go, but the problem I am running into is an inability to see all the

I am having issues with guest OSes running on SLES10 (Sun 4200) hosts. Periodically, the guest OS system drops off the network. From the general network it is not pingable, consequently, ssh fails. If however, I log into the SLES10 server that is hosting the guest OS and ssh to the guest OS, then it becomes immediately pingable and accessible to the rest of the network. Almost like the

Hi, until now, i have been using Xen 3.0.2. Now i upgraded to Xen 3.0.4. Can anybody confirm, that the ordner in the config files for the network interfaces has not changed? My config file used to read: vif = [ ''bridge=xenbr0'', ''bridge=xenbr1'' ] So inside the DomU, eth0 was attached to xenbr0 on the host and eth1 was attached to xenbr1. Now i upgraded to

I have a Xen DomU configuration that was made in the days before libvirt and virt-install. In this configuration I have: vif = [ ''mac=00:16:3e:05:06:01, bridge=xenbr0'', ''mac=00:16:3e:05:06:0a, bridge=xenbr1'' ] and then in xend-config.sxp I define (network-script my-network-bridge) where my-network-bridge is in the scripts directory and looks like this:

Hello all, I have been running xen for a while now with two interfaces: dummy0 for host only communication, and eth0 for the outside network. my script looks like this: (/etc/xen/scripts/network-bridge-more) ------------------------------------------------------------------ #! /bin/sh dir=$(dirname "$0") "$dir/network-bridge" "$@" vifnum=0 netdev=dummy0

Hi, XEN confused me very much. In the config file I had: vif = [ ''mac=00:16:3e:ff:3b:18,bridge=xenbr0'', ''mac=00:16:3e:c0:92:08,bridge=xenbr1'' ] The idea was to connect eth0(peth0) via xenbr0 to DomU''s eth0, and eth1(peth1) via xenbr1 to DomU''s eth1. However it turned out that the first address is assigned to "eth2" in DomU,

Hi! I''m not new to Xen but I''m new to this list. I''m having a truely bizarre problem with Xen bridged networking at the moment. This is a new install, on RHEL4. The symptom is that any domU set up simply fails to talk to anything else. It''s there, and running, and it has an ethernet device, but there''s never any response. After digging through the

Hello, I am having a frustrating time trying to get bridge networking working. I''ve gone over the Wiki page on the topic, a few of the howtoforge pages and everything that I am doing is failing utterly. What I want to achieve is to have Dom0 be a stub running two DomUs. One DomU being a router/firewall and the other being the rest of what is on the current machine.

Hi, I''m working a lot with xen and migration. Now I switched to Xen 4.2 which is really nice. But there is one big problem. A performence issue. I used Xen 4.1 with a networkbridge by using the following line in the vm-config: vif = [ "bridge=eth0,script=vif-bridge" ] In Xen 4.2 this is not possible anymore so that i have entered the following in my /etc/network/interfaces: #
