Hi, I have a PC with 3 ethernet interfaces. I am trying to a) assign 2 ethernet interfaces exclusively to one domU by using the late binding method and b) to use a bridge between the third interface and dom0 (that works fine). The goal is to not to have to use bridges for the exclusively assigned interfaces. Is it possible? (If not, no need to read the rest) The problem I have is that I

Hello, I have a server with 4 NICS running CentOS 5.2. I have bonded the interfaces together such that 'bond0' consists of eth0-3. This is not a problem, and works fine. However, I now need to create a virtual interface. In a non-bonded server I would just create something like eth0:1, but with a bonded interface I am a bit confused. I have created bond0:1 simple by copying the

Hello Everyone, I have set up a xen server with 10 physical network devices using the bridge mode of XEN. This is because I want to split and separate the network traffic for security reasons. Maybe the best way is to use pci back hide. But I want to understand what is going on here. For all testings I have only activated eth[0-3]. My first tests were successful. I have created a VM using

Hi, I would like to ask concerning problems after installing xen 3.3 on Centos 5.2 I use 2.6.18.8-xen (xen3.3.1 testing - installing with mercurial). After done with make world and make install, I did mkinitrd and placing it in /boot changing the grub and reboot.. succeded I do not install libvirt and the domUs from the previous xen 3.0 (built-in Centos 5.2) are NOT able to start : [root@wing

I have followed the nat advice from this guide: http://wiki.kartbuilding.net/index.php/Xen_Networking#Routed_Networking_with_NAT_2 I have googled internet for weeks and read almost every thread in this forum without getting a working NAT on my system. My main question is how exactly will the iptable rules with MASQUERADE or POSTROUTING look like if you want access to the internet from Dom U ,

Hi I;ve trixbox installed with 2 NICs. One NIC carries the MPLS-VPN traffic (only a 1 MB link without internet for carrying voice to another site) while the other NIC has a connection with public IP for internet services on that machine. the first NIC (eth0) has IP of 172.16.0.1 and is connected to router with WAN IP: 10.18.6.254 , the second IP is 203.234.82.98 (eth1). i want to have the

I just did a fresh install of centos 5.0 from cd, followed by yum update which installed 399 packages. No failures or errors that I can see. I have three nics in the box, but am only setting up one at the moment. The box can ping others in my network, but if I try ssh, telnet, ftp, etc I get this: [root at cm network-scripts]# ftp watchdog ftp: connect: No route to host ftp> [root at cm

We had problem using tagged vlans inside domU. Testing shows that this is caused by changing network interfaces in network-bridge script. Following patch should allow to use vlans in guest. Testing scenario: configure vlan network (e.g. vlan 1 on eth0 => eth0.1) start xend create domU and configure same vlan inside it You can see that vlan is still <interface>.<vlan_id>. You can

OK, I have a strange problem. It is probably something simple/stupid, but I cannot figure it out. I have a nice new PowerEdge T20 that I installed CentOS 6 (6.5) on with Virtualization (KVM). I then installed Ubuntu 14.04 in a virtual machine, with a bridged network: ------ begin ub140464.xml------------------ <domain type='kvm' id='2'>

I am running Xen on Debian wheezy. I switched from routed networking to bridged networking. Now I can''t seem to get eth0 to come up. When the network script tries to bring it up, it gets an error: RTNETLINK answers: File exists Any tips? details below brian root@trout:/etc/xen# egrep -v ''#|^ *$'' xend-config.sxp (network-script network-bridge) (vif-script vif-bridge)

I''ve been using Puppet now for a month or so and I''ve come to a problem that may warrant an additional Puppet metaparameter. I''m advocating the addition of a metaparameter called "preaction" (or something like that), which will perform some arbitrary action before the resource is modified. There may be a way to do this within Puppet already (with some

Hi all, I have a strange problem with GPL PV 0.8.8 (0.6.4 did work). On my 2nd vif I cannot establish TCP connections. The 3rd IP packet (ACK from XEN-Image) is not forwarded by XEN/DOM0-Bridge. If I boot Windows without /GPLPV option, everything works fine. I did some investigation and found out that the packages arrive differently if GPLPV is enabled. "br_inet" is a bridge

Has anyone ran into this issue before? 2 physical nics: eth0 hooked up to 10.175.8.0/21 eth1 hooked up to 10.150.8.0/24 Ifconfig -a looks like this: [root@mgixen1 ~]# ifconfig -a eth0 Link encap:Ethernet HWaddr 00:19:B9:F2:1B:C3 inet addr:10.175.8.158 Bcast:10.175.15.255 Mask:255.255.248.0 inet6 addr: fe80::219:b9ff:fef2:1bc3/64 Scope:Link UP

Hi, I''m using Xen 3.0.3 on two servers with Debian Etch (amd64). These servers have 10 nics (2 onboard and 8 in two 4-port cards) so that every vm can have its own interface. This worked so far with the Xen Version from Etch with a wrapper script wich started 10 bridges at boot time. But now I''ve updated Xen on one of these server to Xen 3.2.0 from backports.org and now the

Package: xen-utils-common Version: 4.0.0-1 Severity: important If using ethernet bonding and network-bridge with xen the network-bridge scripts breaks the network. I have run through the commands manually in irder to establish the culprit. In the op_start function (Starting on line 214) everything is fine up until line 251. At this point the bridge has been created, devices renamed and the

Hi Folks: I have a strange problem with multiple (2) NICs on a CentOS 5.5 dom0 setup running xen 3.4.3 and have been struggling to fix it for some time. I could not find anything by googling or searching through this list but that is probably because I couldn''t figure out the correct search terms. After I configure my bridges the command "system network restart" fails for eth1

In /etc/shorewall/masq I have: eth0 eth1 eth0 vmnet1 eth0 vmnet8 ------------- eth0 is my default route to the Linksys router connected to the cable modem. eth1 is my connection to 192.168.1 subnet and it is the gateway for all other machines on this subnet. My routing table is: # netstat -nr Kernel IP routing table Destination

Apologies, there is a slight change required to the solution. replace the do_ifup line as follows: if [ -n "${slaves}" ]; then ip link set dev $bridge up [ -n "$gateway" ] && ip route add default via ${gateway} else do_ifup ${bridge} fi -- Philip Ward Unix Systems Administrator 01786 467274 (ext 7274) -- The Sunday Times

We have been using Xen as our vm only recently (about a year now). We recently started to look at the tcp flow control that is coming in and out of the VM. Our configuration is that a physical interface on the host, peth1, is connect to vif1.1 by bridge br1, vif1.1 is instantiated as eth1 inside the vm. We have a data source attached to eth1 that over subscribe the data capacity of peth1.
