Structure of the Xen source code hi all, I installed Xen on my Gentoo machine successfully from source. Now i am going through the code. instead of banging aimlessly for a week or so i thought i should ask the mailing list the following small doubts. I noticed that following directories are there in my xen-3.0.3_0-src directories. 1. linux-2.6.-xen-sparse 2. pristine-linux-2.6.16.29 3.

paging mechanism clarification Hi All, The Xen uses 2 level Paging Mechanism to resolve the Virtual Addresses into frame numbers from domU.The first level is taken care by the MMU for the domU i.e translation from virtual address to the physical address just like normal paging mechanism. The second level of translation is done by the Xen hypervisor.It translates the pseduo physical address

Package: xen-utils-3.0 Version: 3.0.2+hg9681-1 Severity: normal I get this error with xen after some debug cycles, start / stopping nodes. I found this fix on the net, which fixes the problem: http://lists.xensource.com/archives/html/xen-users/2006-04/msg01070.html in /etc/init.d/xen: start) + modprobe loop max_loop=64 + cd /dev && /dev/MAKEDEV loop xend start

I am setting up Xen for the first time and have run into a problem. My system was initially setup with Fedora Core 4. I was able to successfully create a File-backed VBD. When I boot the domain,I get an error message that is listed at the end of the below boot messages. I suspect the problem is casued by my fstab. However, I am not sure how it should be configured. Fstab listed also. Any pointers

Hello, I just upgraded my 64-bits dom0 from Etch to Lenny, I am still running the 2.6.18 Xen kernel by apt-pinning it (see later). But now xend does not start anymore: ------------ xen:~# /etc/init.d/xend start Starting XEN control daemon: xendTraceback (most recent call last): File "/usr/lib/xen-3.0.3-1/bin/xend", line 40, in <module> from xen.xend.server import SrvDaemon

Just wondering if this is a known bug? Trying to migrate the VM off to a diff dom0 results in the below error. Other VMs migrated off fine (started at around the same time as this vm) and I''ve tried a few different target servers, all resulting in the same thing.

Hi all, after an emerge I wasn''t able to run xen correctly. Everytime I try the command xm list, I receive the error: Error: Unable to connect to xend: Connection refused. Is xend running? Inspecting /var/log/xen/xend.log i found that xend doesn''t find something at line 1 column 0. But I don''t know what is it. I tried with kernel 2.6.16.52 and with 2.6.20-r4 but

Hi, I have recompiled xen-3_3.4.3~rc3-1 in Lenny, together with the 2.6.32-10 kernel. While my dom0 boots without issue under Xen, xend refuses to start. I have cut/past my xend.log is bellow. Is there any reason why a backport of this version of Xen wouldn't work in Lenny? Should I try the already compiled SID binaries in Lenny without trying to build myself? Cheers, Thomas When I start

Hi everyone, I managed to install xen 4 on ubuntu lucid. I managed to read around what kernel configuration options are needed. The problem is that xend can''t start.

Once Xen calculates nr_nodes properly, all nr_cpu calculations based on nr_nodes * sockets_per_node * cores_per_socket * threads_per_core are broken. The easy fix is to replace those calculations with a new field, nr_cpus in physinfo which is calculated by num_online_cpus(). This patch does so and attempts to change all users over to nr_cpus field in physinfo. This patch touches

Testing on an 8-node 128-way NUMA machine has exposed a problem with Xen''s nr_cpus calculation. In this case, since Xen cuts off recognized CPUs at 32, the machine appears to have 16 CPUs on the first and second nodes and none on the remaining nodes. Given this asymmetry, the calculation of sockets_per_node (which is later used to calculate nr_cpus) is incorrect:
