Hi,all I want to get a relatively accurate cpu usage of a domain. I have a few questions about virDomainGetInfo: struct virDomainInfo{ unsigned char state : //the running state, one of virDomainState unsigned long maxMem :// the maximum memory in KBytes allowed unsigned long memory :// the memory in KBytes used by the domain unsigned short nrVirtCpu :// the number of virtual CPUs for the

http://libvirt.org/html/libvirt-libvirt.html#virDomainInfo http://libvirt.org/html/libvirt-libvirt.html#virVcpuInfo Both virDomainInfo and virVcpuInfo have a nanosecond cpuTime field. How do the two related to one another? With some experiementing, it appears the virDomainInfo::cpuTime is equal to the host CPU time used by the qemu-kvm process for the domain. It also appears that the

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

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, Regards, Sherif

Hi All, I am using the libvirt-0.5.1.jar and downloaded from this link ftp://libvirt.org/libvirt/java. 1) To find the os type of domain I use this method getOSType(). But it returns the kvm or hvm instead of windows and linux. Is the any way to find the original os type of domain? 2) Please give is there any option or method available to find the ipaddress of domain? Thanks & Regards

Hi,        Is it possible to get the CPU usage of a guest through a virsh command? I have tried almost all the commands (vcpuinfo, cpu-stats, etc.) that gets the details of a guest cpu, but it only returns the cpu time. Is there any command that returns the cpu usage (just like the graph that virt-manager displays) of a guest? Or do I have to create a program using libvirt API? Thanks in

Hi Team, I have written below code to get the VM state at run time. I found, though the VM is in shut-off state, when I use the function virDomainGetInfo(); I get state as running. Could you please let me know what wrong I am doing. To know the actual VM state I used 'virsh list' and it clearly shows the VM is in shut-off state. Please find the log and code snippet below. Log from virsh:

Hi everyone, I’m testing the new openstack kilo on ubuntu15.04 and hypervisor is xen4.5. I can creat instance successfully , but live migration is always failed.

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

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.

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

I have a Windows XP vm and would like to know how should I set its cpu so it is seen by the vm as a proper 32bit one. In its xml file, I have <os> <type arch='i686' machine='rhel6.2.0'>hvm</type> <boot dev='cdrom'/> <boot dev='hd'/> <bootmenu enable='yes'/> </os> And this is the machine I

The series introduces auto-generation of the type definitions used in the libxl interface followed by auto-generation of a destructor function for each type. In the future it may be possible to use the related data structures for other purposes, for example auto-generation of the functions to marshal between C and language binding data types. tools/_libxl_types.h should be identical both before

Hi all, This is the second take of a patch that I submitted some time ago for allowing specifying vcpu pinning taking NUMA nodes into account. IOW, something like this: * "nodes:0-3": all pCPUs of nodes 0,1,2,3;  * "nodes:0-3,^node:2": all pCPUS of nodes 0,1,3;  * "1,nodes:1-2,^6": pCPU 1 plus all pCPUs of nodes 1,2    but not pCPU 6; v1 was a single patch, this is

I understand that libvirt provides async events that are triggered once the block job reaches ready state and successfully pivots as it is reported by qemu. Whats the event that is triggered and what's the handler that we have to implement? To be more specific, I am looking for the onEVENT callback method that is invoked when the event is fired.

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
