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

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 *.*, This is a continuation on the 2 NICs thread after some more testing. Just to remember my goal. --------------------------- I want to create a domU with 2 virtual NICS. One of them will contact the outside world, the other one will contact a VPN. No reason in concrete for choosing the bridging protocol, only because its the default one. I installed the dom0 with the 2 NICs active, with

Hello all, I have a Xen server with 6 network interfaces, I want a bridge on all of them. I use a personal network script like this : #!/bin/bash dir=$(dirname "$0") "$dir/network-bridge" "$@" vifnum=0 netdev=eth0 bridge=xenbr0 "$dir/network-bridge" "$@" vifnum=1 netdev=eth1 bridge=xenbr1 "$dir/network-bridge" "$@"

Hello all, I would like to use two network interfaces. It is working but I notice that both bridges hace the same id. #brctl show bridge name bridge id STP enabled interfaces xenbr0 8000.feffffffffff no peth0 vif0.0 vif10.0 xenbr1

I have seen those documents, I did not see anything that indicates how _automatic_ bridge configuration could be enabled with xl. For my specific set up I have two bridges (xenbr0 -> peth0 & xenbr1 -> peth1). If I have to configure this manually with ifcfg scripts I will, but if an automatic method is provided or is possible with xl I'd prefer to use that. -Gene On Thu, Jan 29,

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

CentOS 5.5 Xen "standard" Xen Installation. I have two nics. I just put the second one to DHCP and modified the ifcfg-et01 and so far I am holding, but I am not confident. Prior they were sequential IP Addrs on same subnet. arpwatch has indicated flip flips. I can find no rhyme or reason to predict them. I know I missed I must have missed a step somewhere. I want to keep the

I am writing this email in the hopes of getting some advice from Xen users. My main concern is performance and stability. Before I get any further, let me explain the environment: 1. I am using redhat enterprise linux 5 with the xen kernel (2.6.18-8.1.1.el5xen). This is on a Sun X4200 with two dual core AMD processors, 16Gb of RAM, a Sun StoredgeTek 3320 attached to the X4200,

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

I have a OpenSuse 10.3 with xen 3.1.0 running and it''s been running fine for a few months. This past weekend it suddenly started to act up and after some troubleshooting I can now say that it seems like the guests(domU) loose the outgoing network pipe, from the console I can see that the TX counter is stuck at the same value but it''s no errors. It behaves as if whatever I try to

Hello, The basic details of my host and XEN configuration and network configuration all appear below. Whilst I have come this far, a lot of it has been intuitive so I now have plenty of questions. Firstly I would like some help and clarification with regard to ebtables and especially how it works in a Virtualized environment on Novell SUSE 10 SP1 (1) ebtables Installation ebtables was not

Hi list! I''m trying to figure out a way to use network configuration scripts provided by the distribution to manage network/bridge configuration with xen.. This means I dont''t want use xen "network-bridge" (or any other) script at all, because they are a bit limited in functionality. I want to setup VLAN interfaces with the scripts/tools provided by the

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

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 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

Hi, I''ve set up identical (what I think) machines using SLES 10 x86_64, but a new one of those is saying frequently in /var/log/messages: kernel: bond0: received packet with own address as source address A short summary of ifconfig looks like this: bond0 Link encap:Ethernet HWaddr 00:14:4F:2A:12:9C inet addr:132.199.176.78 Bcast:132.199.255.255 Mask:255.255.0.0 eth0

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, 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
