Hello, Just did a fresh install of xen-4.0 and using the 2.6.31.13 dom0 kernel. I have 6 linux debian guests running, and on my host console i am getting these errors rolling pretty constantly. "Attempting to checksum a non-TCP/UDP packet, dropping a protocol 1 packet" I tried doing the ethtool -K eth0 tx off and same thing on peth0, using bridged mode for network config. Any tips?

Hello I've stumbled upon a problem for inversion of a matrix with large values, and I haven't found a solution yet... I wondered if someone could give a hand. (It is about automatic optimisation of a calibration process, which involves the inverse of the information matrix) code: ********************* > macht=0.8698965 > coeff=1.106836*10^(-8) >

Package: xen-utils-common Version: 4.0.0-1 Hello guys, Ik running Debian stable (squeeze). I run a virtual pfsense firwall in a DomU. I created multiple bridges. The interfaces itself (except eth2 (connected to br_lan)) itself don't have a IP assigned. I use them to connect to other devices. grep my-network /etc/xen/xend-config.sxp (network-script my-network-script) root at

Hi all, it''s happening a strange thing: After I boot the xen dom0 network is unavailable: I have to unload the network modules and load it again ( rmmod / modprobe) and execute a service network restart) This is strange, what do you suggest me to check?

Hello everyone, I''m studying XEN these days, and totally a newbie for XEN world. Recently, I''m assigned to move our OS to run on XEN, I means, paravitualization. I know a bit about XEN technique, and I tried to look into Linux code, but it seems too many threads to get understood it ... Now, I have no idea how to proceed my project... Can anyone give some advice? Any suggestion

Hi, I have two physical machines connected through a switch in a 192.168.1.* subnet. Dom0''s are assigned static ip addresses 192.168.1.100, 192.168.1.101 respectively. Dom0''s can ping each other. Each physical machine has a domu guest and static address assigned to domu''s are 192.168.1.200, 192.168.1.201 respectively. However domu''s can neither ping each other

Hi, Creating a new domain is a lot easier in opensuse 11. I follow the instruction on the website and build a virtual machine which uses opensuse 11 as well (I installed it from iso image). Everything works fine except the network. I cannot access the Internet from DomU. Here is some information. P.S. the DomU id is 1. "brctl show" in Dom 0: bridge name bridge id STP

Hi, I have the following piece of code that is part of a larger function. This piece is the most time consuming part of the function, and I would like to make this a bit more efficient. Could anyone suggest a way to do this faster? In particular, I would like to replace the nested "for" loop with a faster construct. I tried things like "kronecker" and "outer"

Package: xen-utils-common Version: 4.0.0-1 Severity: normal Tags: patch do_ifup() in network-bridge exits badly, if the interface doesn't have a default gateway. Since it's wrapped in xen's locking script it causes it to be retied 100 times and sleep for 95 seconds before it continues. In my setup this amounts to: 16 vlans without a default gateway * 95 secs / bridge = 25 minutes

I am moving this to r-devel. The problem and solution below posted on r-help could have been a bit slicker if %*% worked with multidimensional arrays multiplying them so that if the first arg is a multidimensional array it is mulitplied along the last dimension (and first dimension for the second arg). Then one could have written: Tbar <- tarray %*% t(wt) / rep(wti, each = 9) which is a bit

Recently I installed Xen on my computer.But there are some problems during the starting time. The /var/log/xen/xend.log is follows: [2011-06-10 14:24:36 1395] DEBUG (XendDomainInfo:1794) Storing domain details: {''cpu/3/availability'': ''online'', ''description'': '''', ''console/limit'': ''1048576'',

Hi, I''m using Xen 3.0.3 on two servers with Debian Etch (amd64). These servers have 10 nics (2 onboard and 8 in two 4-port cards) so that every vm can have its own interface. This worked so far with the Xen Version from Etch with a wrapper script wich started 10 bridges at boot time. But now I''ve updated Xen on one of these server to Xen 3.2.0 from backports.org and now the

I'm also seeing this error in a very similar setup $ cat /etc/xen/scripts/network-dualbridge #!/bin/sh dir=$(dirname "$0") $dir/network-bridge "$@" vifnum=0 netdev=eth0 bridge=xenbr0 $dir/network-bridge "$@" vifnum=1 netdev=eth1 bridge=xenbr1 but in my case, each interface that is setup with a bridge already has an IP assigned to it via /etc/network/interfaces

Hi, I just tested in the lab the new CentOS 5.1 Xen and find out it breaks network connectivity, at least in my setup. It seems it is somehow making use of the 3.1 Xen version (altought I am not sure about that) but whatever changes it introduce is not documented at the location one would expect, the obvious new thing (at least for me) is this thing I will call out of guessing a virtual

Hi Keir, For HVM guests, all cpuid Fn''s going through domain_cpuid() iterate over the loop and then return 0 for all four registers. Guests OS''s and cpuid tools in HVM which query for cpuid Fn 0000.0000 %eax and 8000.0000 %eax, see the value 0 and think, Xen emulates oldish 386/486 CPUs. This leads to strange boot failures, "your CPU does not support long mode" or

Hello. I need your help, DomU xen network diconnects randomly, how do you monitoring this? When I connect to vnc server in the hosts, DomU is running, then I open the DomU, after that guest network responds. DomU Debian 6.03 over Centos 5.7 and Xen 3.03. My network configuration: eth0 Link encap:Ethernet HWaddr 68:B5:99:78:AA:6D inet addr:192.168.5.230 Bcast:192.168.5.255

I am currently using a Dell PowerEdge server R610 with Xen 4.0 installed and the 2.6.31.13 pvops kernel. I am accessing the server console using the iDRAC KVM feature of the dell management console. Does anyone know how to configure the console option in the grub menu so that all the boot messages can be seen on the mgmt console? Currently I can view only the Xen bootup messages if I dont specify

Hi there guys. I''m using CentOS 5.4, I was able to compile my custom Dom0 kernel and boot it, now I''ve got some doubts. I''d like to compile a custom DomU image, the problem is that when I do, make kernels KERNELS="linux-2.6-xen0 linux-2.6-xenU" it tries to download the kernel from the HG repository which seems to have old 2.6.18 kernels, I want to use the GIT

Hi everyone, I am working on a project whose goal is evaluating the performance of the vTPM Manager. For this project I am using Xen 4.1, Kernel 2.6.31.13 with Fedora11. I I finished all installation and configuration parts. Now I need to boot the system with Xen but while booting, it is freezing at the step "scrubbing free ram". What can be cause this problem and how can I figure it
