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

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 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:

Hi, I've been using CentOS & Xen on a server that has 2 VM's configured. The default configuration includes one physical iface that is propagated (by a default bridge) to the VM's. Since I wanted to configure additional physical iface, define a new bridge and propagate it to the viface-s of the VM's, i configured the bridge/phys. iface and brought it up (here are

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 all, I have observed a problem with a diskless PXE client I am attempting to configure. PXE/NFS/DHCP/TFTPd server is running CentOS5.1 and the Diskless workstation's root and kernel was extracted from a CentOS5.1 (custom kernel due to setting to enable Root File System support). Problem: When the diskless client boots and logs in I notice that my root user is being squashed, even if I

Hi Everyone, I''m seeing this message pop up on my console every now and again (or something similar): blkback: ring-ref 8, event-channel 6, protocol 2 (x86_32-abi) Is this a cause for concern? I''m using Xen 4.1.0 from Gitco and using the CentOS Dom0 kernel (2.6.18-238.12.1.el5xen) Any help is appreciated Thanks _______________________________________________ Xen-users

Hi. I have another question, hopefully easier than my last: Do all physical interfaces in dom0 need to have an IP addresse in order to be used as a bridge by guest domains? I thought that the interface would have to merely be "up" but not necessarily have an IP address configured since bridging is done at layer 2. But alas, if I don''t configure an IP address on dom0 the bridge

Here are three small patches that I have applied to the Fedora xen builds and I think are are suitable for xen-4.1.0. The first patch fixes an anomaly in /etc/xen/scripts/network-route. Currently this script contains netdev=${netdev:-eth${vifnum}} ie. netdev is set to eth${vifnum} by default. Unfortunately vifnum is not set anywhere in the xen code so the default is actually the broken

I''m getting the error: xend (12, ''Cannot allocate memory'') From the command line after the Dom-0 goes through a period of heavy memory usage. I don''t have any hard numbers on how to duplicate it, but I''ll give you the steps I''ve gone through to duplicate the problem. First, some information about my setup. It''s a new setup, and has

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,

Hello!

Hi all, Up until now, we''ve been using Xen 3.0 on CentOS 5.x. Under this setup, dom0 was given a virtual ''ethX'' with the original ''ethX'' (now ''pethX'') IP address. Under this older config, neither ''pethX'' or ''xenbrX'' had an IP address. The logic was to keep traffic from the domU''s, through

Hello All, Consider a CentOS-5.1 Xen server (2.6.18-53.1.4.el5xen) hosting two domains running CentOS-5.1 (2.6.18-53.1.4.el5). One domain has a fairly accurate clock, the other domain has a clock that gains ungodly amounts of time, roughly one minute every two or three minutes. For a fix, one suggestion is to run this command in DomU: echo 1 > /proc/sys/xen/independent_wallclock This

Hi, One of my servers in a IDC in another country mysteriously went down this morning, and when I contacted the IDC, I was told that XEN doesn''t boot up, as follows: [QUOTE] This is error message on the screen " Error 19: Linux Kernel must be loaded before initrd" Server is currently up with 2nd kernel. Please check the grub.conf. [/QUOTE] Looking at grub.conf, I see the

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" "$@"

Hi there, I have a Dell T3400 Workstation with CentOS5.1 as dom0. I have hidden a network interface in dom0 to pass it to domU. The domU can come up with the NIC when it''s OS is CentOS5.1 or RHEL5. But when it comes to RedHat4.5 , the NIC can not be found. As I type the command "lspci" in RHEL4.5 domU, it returned: pcilib: Cannot open /proc/bus/pci

Hi all. What is the canonical way of getting xen to fully work with 802.1q (vlans) ? After (re)searching i found many ways but so far none is working. platform is gentoo (x86/32) and netwerk card a tg3. xen is v3. my config is as follows ... eth0 is simply up (with no ip) and i created several eth0.x interfaces corresponding to several vlans. eth0.10 is de ''default'' vlan

Hey all I''m new to Linux and Virtualizing. I''m trying to dedicate my nic''s to each virtual server. For instance, virt server A would use nic1 and virt server B would use nic2 and so on. I''ve been reading some stuff for this list and to tell you the truth I''m a bit overwhelmed. We are going to run SLES10.1 and Xen. I would appreciate any assistance.
