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")

Hi, These set of patches are affected by replacing bios_relocate hook with bios_load hook in hvmloader. The patches for code files config.h and hvmloader.c also contains part of the contents of Enabling UEFI BIOS(OVMF) support in Xen-unstable HVM. Is there any problem with these patches? Thank you very much. # HG changeset patch # User gbtju85@gmail.com # Replace bios_relocate hook with

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

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

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

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 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 ''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

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!

A buggy or malicious frontend should not be able to confuse netback. If we spot anything which is not as it should be then shutdown the device and don''t try to continue with the ring in a potentially hostile state. Well behaved and non-hostile frontends will not be penalised. As well as making the existing checks for such errors fatal also add a new check that ensures that there

Netback and netfront only use one event channel to do tx / rx notification. This may cause unnecessary wake-up of process routines. This patch adds a new feature called feautre-split-event-channel to netback, enabling it to handle Tx and Rx event separately. Netback will use tx_irq to notify guest for tx completion, rx_irq for rx notification. If frontend doesn''t support this feature,

time_after_eq() only works if the delta is < MAX_ULONG/2. For a 32bit Dom0, if netfront sends packets at a very low rate, the time between subsequent calls to tx_credit_exceeded() may exceed MAX_ULONG/2 and the test for timer_after_eq() will be incorrect. Credit will not be replenished and the guest may become unable to send packets (e.g., if prior to the long gap, all credit was exhausted).

This patch adds code to handle SKB_GSO_TCPV6 skbs and construct appropriate extra or prefix segments to pass the large packet to the frontend. New xenstore flags, feature-gso-tcpv6 and feature-gso-tcpv6-prefix, are sampled to determine if the frontend is capable of handling such packets.

VM traffic is already limited by a throughput limit, but there is no control over the maximum packet per second (PPS). In DDOS attack the major issue is rather PPS than throughput. With provider offering more bandwidth to VMs, it becames easy to coordinate a massive attack using VMs. Example: 100Mbits ~ 200kpps using 64B packets. This patch provides a new option to limit VMs maximum packets per

This dependence is undesirable and logically incorrect. It''s undesirable because Xen network protocol should not depend on a OS-specific constant. It''s incorrect because the ring slots required doesn''t correspond to the number of frags a SKB has (consider compound page frags). This patch removes this dependence by correctly counting the ring slots required.

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

Hi Attilio I have updated to the upstream Xen and try to boot into OVMF bios. Instead of fetching the OVMF code from the git mirror, I just copy the OVMF bios to ovmf directory. I use the bios="ovmf" in the HVM config file. But, there is an error when I create the domain. root@gavin-laptop:~# xl create hvm_ubuntu.hvm Parsing config file /root/hvm_ubuntu.hvm WARNING: specifying

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| | |
