similar to: Measuring performance using Xenmon

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

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

Hello, When I install guest OS on xen using "xm create /path/of/file/ubuntu.cfg -c" , I am getting an error message *"Error*: Device 0 (*vif*) could not be connected. Hotplug scripts not working <http://markmail.org/message/24aj3qs6ddrtwdks>" . I also saw that hotplugs and udev are prerequisites to be installed before compiling xen. I could not find hotplugs in Yast.

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, 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

Hi list, I''m working on monitoring CPUs usage per domU, I/O.... using xenmon parsing its output and finally polling the results with cacti. Any advices? If all works OK I will post my work to the list.

In XenMon''s file appending mode, a lot of times I''ll get a strange first data point, e.g., the cpu% for dom0 will be 99.9 but the rest of the readings will be 19-21 which are sane for the run. I''ve been throwing the data point out, but was curious about it. Is it unavoidable? Thanks, Tim _______________________________________________ Xen-devel mailing list

Hi, I read about RPC interface for xenmon in this presentation: www.xensource.com/files/xs0106_xenmon_brief.pdf Has such interface been implemented yet by anyone?

Hi, I am facing the below error while compiling dom0.

Hi, Libvirt provides classes such as Xen_ComputerSystem, Xen_Processor etc., in order to build applications using libvirt-api which can interact with the Xen Hypervisor. I would like to know what are the corresponding classes for the KVM hypervisor, so that I can use libvirt-cim to communicate with the hypervisor. Would it be Kvm_ComputerSystem or Qemu_Computersystem? Any help in this regard

All, similar to some mail threads found in this forum and some other xen-related threads, I had problems with the network performance of my test system: * software base of dom0/domU: RHEL5 (Xen 3.0.3, Redhat 2.6.18-8el5xen SMP kernel) * ibm x306 servers with 3Ghz P4 /MT support; coupled via Gigabit Ethernet switch * standard xen bridging network configuration * test tool: iperf * Xen

Hi, In continuation with my previous mail, I changed the vif entry in the config file as, vif = ["mac=00:16:3e:43:b7:99,bridge=xenbr0"] and I was able to boot into the guest, but I was not able to ping any system from the guest. I have attached the snapshot of the boot error messages. Thank you Regards Ananth -----Original Message----- From: CB, Anantha Padmanabhan Sent: Wednesday,

Hi, I am trying to connect to libvirt on KVM host from a remote python client, using the connection string "qemu+ssh://<IP Address>/system" If I setup password less SSH (Public key) between the machines, I am able to proceed with the connection. But If I have not setup the public key authentication, my code hangs trying to connect to libvirt, and there is a prompt for entering

This is probably very simple but my brain has frozen over. (I'm trying to warm it with coffee) I have observations of around 22000 individuals over 13 successive years: they were either 'interviewed' at time t or 'not interviewed'. What's the most appropriate function/approach to use to find out the extent to which individuals' event outcomes are temporally
