similar to: Monitoring and statistics through libvirt

Hi, I am trying to create a report across all my KVM hypervisors using libvirt API and I need some assistance in figuring out the right API calls. My report will contain the total available memory, CPU, disk across all hypervisors, versus the amount used by the virtual machines. This report will help figure out if we are running low on hypervisor disk, CPU or memory and if we need to add more. I

Would it be possible to list the Host sFlow project in the Monitoring section of http://libvirt.org/apps.html? Host sFlow <http://host-sflow.sourceforge.net/> Host sFlow is a light weight agent running on KVM hypervisors that links to libvirt library and exports standardized cpu, memory, network and disk metrics for all virtual machines using sFlow protocol. Thanks, Peter

Hi Guy, I am trying to figure out how & where can i get the bandwidth usage utilization statistic info for all the VM, so in the end i will be able to use it for metering purpose.. Anyone got any idea ? Regards, Peter -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hello, Recently I''ve received some complaints that there is excessive but intermittent latency of network traffic to domUs on some of my servers. Upon investigation it seems that on some servers, indeed traffic is occasionally delayed by up to 140ms where something like 5ms RTT would be expected. The average RTT is not unusual; since this is only occasional packets it only affects the

Hi, I have noticed that virt-manager has the ability to show me the current cpu- and memory-usage of both the host and running guest machines. How does it do that? I could make good use of that information myself in the client applications I'm writing, however, from what I can see on http://libvirt.org/html/libvirt-libvirt.html, I have no idea how to go about getting it from libvirt. In

Hi all, For anyone that's interested in setting up TLS with libvirt, but hasn't gotten around to it yet, there's a decent guide on the wiki now: http://wiki.libvirt.org/page/TLSSetup It's user focused (ie SysAdmin's), and has lots of pics explaining concepts, plus shows what needs to be done, and shows how to do it. Please note, it doesn't cover SASL, it's just

Hi all, I''ve got XCP 1.0 up and running nicely and would like to use it in production. However I''m struggling with the concept of bandwidth management. It seems like such a common problem that everyone must have, but I can''t find any clear direction in which to go. The dedicated host I am using (Hetzner) gives me a 5TB monthly bandwidth quota which needs to be shared

Hello, I am trying to run SCO unix 5.0.5 with KVM. I have created the Virtual Machine with virt-manager. The installation runs correctly, but when the virtual machine reboots from hard disk, i obtain this message : "FATAL: No bootable device." If i run manually the virtual machine without the suboption "boot=on" in the "-drive" option, the virtual machine boots

Hi, I''m a long ext3 user (rpmfind.net). I propagated ext3 on some of our server box (W3C webservers are ext3 based too now). I might be tempted of testing out your kernel RPMs but unavailability or the source RPM and the SMP version are definite showstoppers. Please provide them. In the meantime I will stick to my own set of kernel ext3 RPMs at ftp://rpmfind.net/pub/veillard/ext3/

Hi Guys I''m trying to measure the traffic of domUs using vnstat without luck. My configuration: Debian 6.0.3 xen 4.0.1 vnstat 1.11 I''m using bonding with two network cards. auto bond0 iface bond0 inet manual slaves eth0 eth1 bond-mode active-backup bond-miimon 100 bond-updelay 200 bond-downdelay 200 bond-primary eth0 auto br0 iface br0 inet static

Hi, Is there any way you can save a xen domain without suspending it or stopping it? I want to set up something so if my xen session crashes I can fire up another xen session from the save file that I created 5 minutes before the crash and hopefully minimize downtime.

I keep getting an error when I try to attach a device in the libvirt api through python The python code is: conn=libvirt.open('qemu:///system') dom = conn.lookupByName("fedoratest") if dom.info()[0]==1: dom.attachDevice('net.xml') And I keep getting: "libvirtError: XML description not well formed or invalid The xml is a simple network

If you need to continuously track libvirt metrics, you might want to install Host sFlow agents on each of your KVM hypervisors: http://host-sflow.sourceforge.net/ The Host sFlow agent is a lightweight daemon that links to the libvirt library on the hypervisor and sends hypervisor and VM metrics using the sFlow protocol to a central collector. You could use an sFlow analyzer like Ganglia to

I converted a system disk from a virtualbox VM and added to the config on a qemu VM. All seems well until I try to mount it. The virtual machine shows data for the disk image using commands like: pvs lvs lvdisplay xena-1 but there is no /dev/xena-1/root to be mounted. I also cannot seem to figure out whether the lvm related modules are available for the virtual machine kernel. Has anyone

I've not seen this asked since I've been on the list; but was wondering... I'm currently sticking to the 2.2 line and have no plans to move to 2.4 right now. Is there any attempt to back port some of the changes in the newer 2.4 line back into 2.2? ext-0.0.7a.tar.gz has been stable thus far, but it's getting kind of old. NEM

Hi all, I'm using libvirt java binding (libvirt-java-0.4.6) I'd like to know if the Domain class offers an API to query volumes attached to a particular domain or should I parse the XML domain description?

Has support for creating or using lxc containers on remote machines been added to libvirt yet? https://help.ubuntu.com/12.04/serverguide/lxc.html says "Libvirt is a powerful hypervisor management solution with which you can administer Qemu, Xen and LXC virtual machines, both locally and remote." so I assume it's been done and I'm just having trouble seeing it... otoh, I hear

Hi, IIR/UC there have been a couple of discussions lately about possible evolution of libvirt's network management features to eventually support more kinds of virtual networking technologies like Openvswitch, VDE,... Could a kind and informed soul keep us on touch with progress in the field ? Thank you very much in advance PS: I wish this will be available before/for 1.0 release...

Are there any recommendations as to how often a new connection should be made versus reused? Right now we create a new connection *every time* we hit libvirt for something. We can easily change this so that a single connection is made for a series of libvirt calls, or even so that a single connection is used for the lifetime of the running application. What are the issues to consider when making
