Hello. I''ve just started with Xen and configuring Dom0. My hardware is Core2Duo based Xeon server and I installed Debian etch for amd64 architecture. The Xen related pachages installed are the following. linux-image-2.6.17-2-xen-amd64 linux-modules-2.6.17-2-xen-amd64 xen-hypervisor-3.0.3-1-amd64 xen-tools xen-utils-3.0.3-1 xen-utils-common My problem is that when xend is

Hello, Where can I find a link (or docs) to *working* network config for xen 4.1.2? My tests (s. below) were not successful. Thank you in advance for any hints. Regards, Mark # --- root@xen411dom0:~# cat /etc/network/interfaces # Used by ifup(8) and ifdown(8). See the interfaces(5) manpage or # /usr/share/doc/ifupdown/examples for more information. auto lo iface lo inet loopback auto bond0

Hi, we''re running 4 xen servers on our network with multiple network cards. During HighLoad we experince degeneration of inbound network traffic through our loadbalancer. I might found a reason for it, in Dom0 dmesg output looks as follows: [1157421.975910] eth0: received packet with own address as source address [1157421.975957] eth0: received packet with own address as source

Package: src:xen-api Severity: wishlist I've tried to configure VLAN using XCP + openvswitch using Wheezy, though it's still not fully working, I think VLAN configuration on dom0 can be better documented. It's fair easy to configure VLAN in Debian. First you need to ensure that your physical switch is in trunk mode, which means it will pass all kinds of VLAN tagged network flow, and

It appears that this issue may be a result of documentation problems When I was having this problem, I had xenbr0 declared in my /etc/network/interfaces file. I have now stripped out everything in the interfaces file except the loopback interface, rebooted, and now my xcp+openvswitch system appears to be adding domUs to the bridge automatically, so the problem is no longer there. Specifically,

Hi, I am an old hand at chemistry but a complete beginner at statistics including R computations. My question is whether you can carry out nonlinear multivariate regression analysis in R using neural networks, where the output variable can range from -Inf to + Inf., unlike discriminant analysis where the output is confined to one or zero. The library nnet seems to work only in the latter

I have some questions regarding xen: My setup is like this: 2 1TB disks with each with /boot and LVM. These two are in RAID1 configuration on the two disks.Also, I have installed Debian 4.0r5 (etch) with kernel 2.6.18. So here are some concerns: Shall I create a new user, chroot it and then create the VMs under this user? I need to check if this is possible. If it would, then would it provide

Hi, I tried to use Intel quad-port ethernet adapter on a server running Ubuntu 12.04.1 (kernel 3.2.27), but the igb driver (version 3.2.10-k) failed to work on Xen 4.1.2 kernel in bridge mode. The content of /etc/network/interfaces follows :- auto xenbr0 iface xenbr0 inet static address ..... ...... bridge_ports eth0 auto eth0 iface eth0 inet manual I checked with brctl and there was no

Hi R users! One thing I cannot understand with R is the frequently appearing " Correlation of coefficients". I do not find a through going explanation of this concept either on the help pages of R or on the internet. A Google search has shown many examples of R/S-Plus outputs but no explanations of meaning. I am afraid this turns out to be a silly and unworthy question. Would anyone be

Hi, Sorry of this is the wrong list, trying to find some help. I am trying to set up 2 KVM hosts using Debian 9 (connecting to a 3 node Centos 7.4 gluster cluster) To get the bandwidth I have bonded 2 NICS each end. However while the network works fine for the Debian VM host the VM guests cannot connect/get an IP using DHCP connecting to br0. (Same setup on the Centos end works fine however)

Hi There. I am in the process of "upgrading" my Xen 2.0.7 server with a Xen 3.0.2, though I am doing so on a different machine. My firewall will be running as a DomU, asit also does on the existing server. The new server is Ubuntu 6.06 and the existing server is Debian Sarge. On the existing server, I have the WAN interface hidden from Dom0 with the two other physical interfaces

hi, i cleared all the stuffs(everything) related to xen and libvirt. i installed freshly xen-4.2.1 from the source. *Installation steps are as follows:* apt-get build-dep xen apt-get install libc6-dev libglib2.0-dev libyajl-dev yajl-tools libbz2-dev bison flex zlib1g-dev git-core texinfo debhelper debconf-utils debootstrap fakeroot *OR* apt-get install bcc bin86 gawk bridge-utils iproute

Dear List, I am trying to solve a problem by the neural network method(library: nnet). The problem is to express Weight in terms of Age , Sex and Height for twenty people. The data frame consists of 20 observations with four variables: Sex, Age, Height and Weight. Sex is treated as a factor, Age and Weight are variables normalized to unity, as usual. I wanted to construct a neural network, and so

Hi everyone, I just got a brand new server by Hetzner.de. The thing is, when you have additional IP, to use routed mode (precisely a subnet of IP, story of exposed MAC in their data center etc.) Bridged mode is NOT possible for getting connectivity in VM''s. Traditionally, I''m more confident with "standard" Xen setup, so it''s easy to switch from bridged to

Hello all, I am new to Linux Ethernet bridging. Let me first start with what I am trying to achieve. Well you see - I am attempting to have 2 main firewall running at the same time - one as a master and the other one as a slave. Yes, I would like to make use of Ethernet bridging in this scenario - as I understand it, all I need are two machines and STP enabled. I am running Debian

I can’t seem to find info about layer 2 tinc tap interface bridge with local physical nic. I have successfully created two nodes configuration with tinc acting as switch. My problem is ethernet packets only flow between two nodes and not to hosts on bridged nic. Example: Server 1 - eth0 bridged with tinc tap device, then bridge gets IP via dhcp server on physical nic subnet. Server 2 - local

I''m converting my network from a "one interface per segment" to a "single connection with vlans", well, some hardware I have requires using different vlan IDs. suffice it to say I need bridges to connect a few different vlans that should all be one but can''t be because of firmware constraints. so my first step is to get shorewall to know about bridges.

Dear R users, I have a data set of 25 cases with 150-160 explanatory variables(the number of which depends on what I choose from 200 odd digitalized spectrum strength numbers) and one dependent variable(a sensory test result). My natural choice is to work on a principal component analysis using the explanatory variables, thus enabling to characterize and describe the data space, and make a

Hi everyone, I have some trouble with the network on a domu on a new host : I''ve made a bridge and configured it but when I start the domu, I can''t ping any network... seems like the bridge is not working :''( I''ve created the bridge directly in /etc/network/interface and I''m using Xen 3.0.3 on a debian etch, bellow are the xen packages installed on
