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 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

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| | |

Hi Guys I''m trying to measure the traffic of domUs using vnstat without luck. My configuration: Debian 6.0.3 xen 4.0.1 vnstat 1.11 I''m using bonding with two network cards. auto bond0 iface bond0 inet manual slaves eth0 eth1 bond-mode active-backup bond-miimon 100 bond-updelay 200 bond-downdelay 200 bond-primary eth0 auto br0 iface br0 inet static

Hi, I have 5 very identical server running xen 3.0.3 (Debian etch std. packages) with serveral DomUs. Theres my question: It is possible to keep thier lvm volume groups or singe logical volumes synchronized over network? Example: dom01 contains: domU1 on volume group xenserver1 with logical volume domU1 and LV domU1-swp domU2 on volume group xenserver1 with logical volume domU2 and LV

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

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

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 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")

Hello, We''ve recently started seeing several domUs on multiple machines losing all network connectivity. At least one of these machines (since they are customer machines I can''t verify it for all of them) give the error: $ sudo ifup eth0 eth0: full queue wasn''t stopped! About the only Google hit for this message is:

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,

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, 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, this is a question I wanted to ask you since a long time because there is something not too much clear to me, as regard the memory management in XEN. I don''t want to go too much in deep with such argument, but It''s just to understand what is the best setup for my environment. I know about memory ballooning (http://wiki.xensource.com/xenwiki/XenBestPractices) and the

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

You are very welcome. One thing that I am working on now involves removing the step toward the beginning: xe pif-reconfigure-ip uuid=<UUID of the bond created above> mode=static gateway=<GATEWAY> IP=<IP ADDRESS> netmask=<NETMASK> DNS=<DNS SERVER ADDRESS> I do not believe that this step is necessary since we will not use the pif directly. We will use

While I am still in the process of working through this here are the steps I am taking to set up each machine. 1) Since each of my servers have multiple NIC ports I bond them together (see page 34 of the Administrators Guide) first. This is best down from the physical server and not via the remote console. If you do it remotely you will then have to reconfigure the management port before

I have Xen3 installed on Ubuntu 6.10 server, $ sudo xm list Name ID Mem(MiB) VCPUs State Time(s) Domain-0 0 250 8 r----- 748.2 but whenever i try to create a new domain with anything listed for kernel at all, i get this: $ sudo xm create domu1 Using config file "domu1". Xend has probably crashed!

Hi All, I find that I am able to attach a disk device do a Xen domain, using virDomainAttachDevice(), running as a non-root user, but I am unable to use virDomainDetachDevice() - it results in an "unknown failure". Using "virsh [attach|detach]-device" exhibits this behviour. $ virsh attach-device domu1 attach.xml Device attached successfully $ virsh detach-device domu1

Hello, I have a network issue in dom0; I''m not sure if it''s a configuration problem or a design problem in my setup. My setup: The server (dom0) runs Ubuntu 7.10, Xen was installed using apt-get (means version: Xen 3.10, Kernel 2.6.22-14). This server has 4 NICs. I use bridged networking with my own script which creates 4 bridges ("$dir/network-bridge"
