Attached is the second release of XenMon, which is a unique performance monitoring tool for Xen. Instead of using hypervisor calls to get domain information, we use the xentrace facility to provide fine-grained monitoring of various metrics (see README below). We have written up a small case study that demonstrates the usefulness of the tool and the metrics that it reports. This will be

Cycling around many CPUs in XenMon''s curses mode can get cumbersome. This trivial patch adds bindings to move to the previous CPU. The next/previous binding seems more natural to me than the earlier cycle binding, but we can keep them all for now. # HG changeset patch # Node ID 146b5c76086c07fad61bea7ccf60f2f4fd66abbd # Parent 7dd31dbf16e75f0f70e0f9c44b2bb2b5fc6eecf1 Add next/previous

Here are some patches I compiled to get sedf_get to the XendClient API... sadly, however, the current xc frontend is missing a variable (weight) and needed to be edited. Below are my "homemade" patches (I did this since my code base is EXTREMELY old... however the code is still valid) tools/python/xen/lowlevel/xc/xc.c line 766 static PyObject *pyxc_sedf_domain_get(PyObject *self,

Hi. I am a student at University of Zurich and I''m doing a homework about Cloud Computing regarding accounting and billing. Because the "big" players use Xen Hypervisor I installed a Xen (3.3.0) on an Ubuntu 8.04 to test some things and get more familiar with Xen regarding accounting. I have two questions: 1. CPU monitoring +++++++++++++++++ I have discovered something

Hi, This patch adds the argument check of "--ms_per_sample=" option. For "--ms_per_sample=", a negative value should be invalid. e.g. % xenmon.py -n --ms_per_sample=-1 usage: xenmon.py [options] xenmon.py: error: option --ms_per_sample: invalid negative value: ''-1'' Signed-off-by: KUWAMURA Shin''ya <kuwa@jp.fujitsu.com> -- KUWAMURA

Hi, I am using Xenmon to measure performance of Credit and SEDF schedulers. But as you know, the metrics displayed by xenmon keep refreshing on the screen. When I tried redirecting the xenmon output, I am seeing the attached file. Is there any better way to record results which I can use to draw graphs? Please guide.. Thank you Warm Regards Ananth

I rebooted xenU from console (dom2) and exited (ctr-]). xm list does not report 2 anymore yet I can log into 2 via console and it is running just fine. Is this a bug? I''ll pull/rebuild and see what happens.. (this is xen-2.0, cset 1.1321.1.1, rh7.3 dom0/dom1) ------------------------------------------------------- This SF.net email is sponsored by: IT Product Guide on

Hi, Can someone clarify for me the numbers that show up in Xenmon? Specifically, I''m curious about the "domain31" entry which always shows up. It looks like this represents the free resources. Also, does anyone know what would happen if more than 30 domain0''s were started (or more likely, I did enough migrations to raise the next domain ID to above 30)? Thanks for

Package: xen-utils-3.0.3-1 Version: 3.0.3-0-2 For some reason, xenmon.py is not in the search path - maybe an issue of the wrapper used by the xen Debian packages seems to be only a link to the wrapper is missing the program exists in the package xen-utils-3.0.3-0-2 and the follwoing make it work: ln -s ../lib/xen-common/bin/xen-utils-wrapper /usr/sbin/xenmon.py ln -s

Package: xen-utils-3.0.3-1 Version: 3.0.3-0-3 Severity: grave Tags: security Justification: user security hole Xen versions 3.x, and 3.1 contain a tool for processing Xen trace buffer information. This tool uses the static file /tmp/xenq-shm insecurely allowing a local user to truncate any local file when xenbaked or xenmon.py are invoked by root. Sample session: # setup. skx

This patch adds new control messages for vcpu hotplug events. Via the xm vcpu_hotplug sub-program, VCPUS in domains can be enabled/disabled when CONFIG_HOTPLUG_CPU is enabled in the target domain''s kernel. Currently there is nothing that tracks whether a VCPU is up or down. My previous [1]patch added a new per-VCPU flag (VCPUF_down) which could be used to keep track of which VCPUS are

Hi, All This is a patch for xentrace.c. This routine checks the trace buffer is initialized or not. If not, the trace buffer is initialized by using this patch. This is avoiding following message. ERROR: Failure to get trace buffer pointer from Xen (22 = Invalid argument) This routine is based on the specification of the trace buffer control function trace.c/tb_control(). The function checks

Right now xm will return 1 if you run `xm list non_existant_domain` Wouldnt it be a better idea to have a specific error code for this error so that scripts wrapping around xm can better determine if the domain does not exist or if xm just failed for whatever reason? ~Shaun _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com

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

Hi, I have installed Xen 3.3.1 with Ubuntu 8.04 as dom0 and fedora9 (from jailtime.org) as Dom1. I have more instances of the same fedora9 with separate config files running as other guest domains. But these guest domains dont have any program / application running. So, xm list shows that they are in blocked state as no activity is happening. I wrote a shell script that counts upto large numbers
