getting CPU usage of VMs through libvirt
Greetings everyone,
I just want to ask if it is possible to get the CPU usage of the VMs in KVM through libvirt? I mean, how does the virt-manager produce the graph it displays? Is there a way get this graph? But instead of the graph itself, I just need to get it in percentage(%) form. I'd like to know how. Thank you and your help will be greatly appreciated.

how virt-manager gets CPU usage of Guest
Hi,
Does anybody know how virt-manager is getting the CPU usage of the guests? I need to know how to get the CPU usage of the guests and this is the only way I can think of. In other words, how does virt-manager produce the graph of the CPU usage of EACH guest in KVM? I don't actually need the graph, I just need to get the percentage(%) since I'm trying to create a Java program to get

Libvirt Java API to get CPU usage of VM (KVM)
Hi all libvirt-users,
Is there a counterpart on Java of the function virDomainGetCPUStats that is based on C API? Because I am trying to create a program based on
java to get the CPU usage of a Guest/Domain/VM in KVM using the Libvirt
Java API.
Honestly, I am having a hard time in starting my program. I have no
idea where to start. I mean, what functions do I need to get the CPU

ESX(i) implemented functions
Dear All,
I would like to know what functions and classes are implemented in the
ESX(i) driver ? i am trying to use virsh to retrieve some simple information
such as vcpuinfo domain, but it is not working, so I would like to know what
functions are implemented in libvirt ESX(i) driver. Also i checked the
http://libvirt.org/drvesx.html and nothing is mentioned there.
Thank You,

About the change of a VM's vcpu count in runtime?
Hi,
We know that there is a command "setvcpus" in virsh used to "change
number of virtual CPUs", now we just have the need to change vcpu count
dynamically for a running VM, so I tried this command (the vcpu count is
2 in the VM xml file), below is the result:
virsh # setvcpus 3 --count 4
error: invalid argument: requested vcpus is greater than max allowable
vcpus for the

using more than 1 core by a virtual machine
My virtual machine xml file has <vcpu>2</vcpu> clause while the host has
2 physical cpus (cores).
Is this enough to cause a VM running 2 endless loop threads to use the 2
cores ?
In my case the VM running reports (cat /roc/cpuinfo) that it has 2 vcpus
but it uses only 1 core (at a time) because
the 'top' at the host shows 100%cpu (out of total 200%) used by the

vcpupin and kvm
Hi.
Can anyone confirm if vcpupin works correctly with kvm? If set I pin a
vcpu it shows up correctly via vcpuinfo, but querying via taskset shows
the cpu is not pinned.
Thanks,

How can openstack retrieve the CPU usage of a lxc via libvirt?
