Hi, I am trying to fix a problem I have for about a week now. The environment is: --several independent servers with Centos5.4 on the latest patchlevel (example will be server2) All of them are working properly. --a machine with Xen installed to host some virtual machines (xenserver1) --domu servers on xenserver1 (crmserver1, winserver1) The whole network is connected with a Lancom router to a

Hi, I updated a server yesterday from "kernel 2.6.18-128.7.1.el5xen" to "kernel 2.6.18-164.el5xen" After rebooting, my message log is flooded every second or so with this error messages: Oct 6 14:52:20 xenserver1 kernel: EDAC MC0: UE row 0, channel-a= 0 channel-b= 1 labels "-": NON-FATAL recoverable (Branch=0 DRAM-Bank=0 Buffer ID = 0 RDWR=Read RAS=0 CAS=0

Hi Keir, I find that you are the author of the netback driver of linux-2.6.18-xen Dom0 and I hope I can get some help from you. I want to quickly have a knowledge about how a data packet is transferred between two VMs on the same Xen hypervisor if the TCP/IP protocol is used. I am not sure whether a data packet from DomU1 to DomU2 is transferred like this: DomU1(front-end network

I am having some problem with partitioning schemes on DomU. I have 10 LV ACTIVE ''/dev/virtualization/domu1-swap'' [4.00 GB] inherit ACTIVE ''/dev/virtualization/domu1-disk'' [146.00 GB] inherit ACTIVE ''/dev/virtualization/domu2-swap'' [4.00 GB] inherit ACTIVE

Hi everyone! I have the following setup: domain0 |-domU1 |-domU2 |-domU3 I am running this with libvirt on a XEN server. Right now the server is connected to our office network, but later it will be in a hosted environment. I need domU1 and domU3 to have a public IP, and all of the domUs and the dom0 should have an internal IP address to communicate with each other. So this is what I would like

Hi all, I installed xen-3.3.1 and configured two DomU with 2.6.18.8-xen kernel. Now the DomU1 and DomU2 could work and the network is ok. But I used the filesystem image from jailtime, so the X-Window mode can''t work. Thus, I tried two ways to make the GUI-mode work: (1) yum install X-Window in Guest OS, and the GUI configuration Wizard shows up. When done with the configuration, the

Hello, is pxelinux intended to work with Token Ring Cards ? cause i have a nice IBM Token Ring PCI Card (olympic) and sadly pxelinux hangs when trying to get the configfiles via tftp... last message: "Trying to load: pxelinux.cfg/<hexip>" but no tftp packet was sent (serverlog empty, ethereal shows no packet either) i tried versions 1.67, 1.75, 2.00-pre4... using ethernet,

Hello I use XEN 3.0 in debian sarge. I have a domU1 for routing and firewall. This domU1 use 2 network interfaces which is on a bridge ''gate'' and the other on bridge ''lan''. dumU2 use one interface (eth0) on bridge ''lan''. Then I make a ping out of domU2 to www.debian.de so I get no answer. The name isn''t resolved. A ping to IP of

Hello everyone. I just installed Xen 3.0.3 in a debian etch box. Linux server1.example.com 2.6.18-6-xen-686 #1 This server1 has two real nic (eth0 with real MAC 00:13:72:57:7B:AE and eth1 with real MAC00:13:72:57:7B:AF). I made a network-bridge custom like this: ----------------------------------------------------------------------- #!/bin/bash dir=$(dirname "$0")

I installed XEN from source, since the binary did not install. The Xen source includes also tools/firmware/hvmloader To compile firmware it only shows a message: WARNING: Install dev86 package to build firmware! At the referred page http://www.cix.co.uk/~mayday I could not find anything about dev86. What do I need to do? I want to install as DomU2 Windows XP and need hvmloader. bye Ronald

I''ve been brainstorming... I want to create a 2-node HA active/active cluster (In other words I want to run a handful of DomUs on one node and a handful on another). In the event of a failure I want all DomUs to fail over to the other node and start working immediately. I want absolutely no single-points-of-failure. I want to do it with free software and no special hardware. I want

Hi all, I use CentOS5.x + Xen in production for virtualization. I use it with bridged vlan networks and bonding (active-backup) like that: eth0 eth1 | | ------- | bond0-------bond0.10---------bond0.12 ... | | | | vlanbr10 vlanbr12 dom0 | | ------------- -------------- | |

Hi, I have some problems with my OpenVPN server in a Xen DomU. OpenVPN works fantastic but theres a problem connecting other DomUs on this server. I have the following iptable rule to forward the requests to the internet. iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -j MASQUERADE This works fine. I can connect to other DomUs on the same server but they can''t answer the

Hi, I ''ve got a CentOS 5.2 server running xen 3.0 with 2 DomUs also running CentOS 5.2. All my boxes are up-to date. I''m experiencing trouble with networking. Dom0 can reach the outside world when no DomU are started. It can also reach the outside world when only one DomU is running. The troubles begin when I start the second DomU. At first, this new DomU, called DomU2,

Hi Guys I''m trying to measure the traffic of domUs using vnstat without luck.

Hi All, I have been trying to solve the issue of Xen-based Virtual Machines (as I described earlier); I have the problem of ethernet ports locked to a single Mac address in my lab--hence VM''s can''t communicate using bridging other than their own dom0. To further test/confirm, yesterday I took my laptop at home and connected to my Home-Hub (which issues DHCP based IPs); I

hi, for some reason i can not get vista ultimate to install. i get to the page where i enter the user name and password and at the next reboot, it just gets stuck in the boot loader - see attachment. the cpu usage goes to 50% and that was it. has anyone else experienced this ? it does boot a couple of times, but i guess that it is from the installation image. created domU using the virtual

Hello everybody, I am in the process of setting up a really cool xen serverfarm. Backend storage will be an LVMed AoE-device on top of DRBD. The goal is to have the backend storage completely redundant. Picture: |RAID| |RAID| |DRBD1| <----> |DRBD2| \ / |VMAC| | AoE | |global LVM VG| / | \ |Dom0a| |Dom0b| |Dom0c| | |

In the Xen case if you can get the Xen dmesg one too (which you may not from a initrd) that would be useful as well.
