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

libguestfs usually needs qemu. However it only requires an emulator for the same architecture, not for all architectures. libvirt-daemon-kvm pulls in qemu which pulls in emulators for all architectures, as well as a bunch of other stuff we don't need at all like network interface support and nwfilter. There are no Fedora TCG-only arches, so drop the conditional section. I also made support

Hi, everyone I'm writing a virtual machine monitor based on libvirt. As I read the api reference, I found I'm confused by some terms. 1, What is cumulative I/O wait CPU time? API reference says that VIR_NODE_CPU_STATS_IOWAIT indicate cumulative I/O wait CPU time. I'm confused by this time. As far as I know, when cpu meets IO wait situation, it will schedule another task, so,

i've reported this issue before, so i guess this is a regression. looks like the python bindings for 0.9.3 are leaking file descriptors: root at cloud1:~# python Python 2.6.6 (r266:84292, Dec 26 2010, 22:31:48) [GCC 4.4.5] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import libvirt >>>

HI, I am using ubuntu host machine and KVM is present as guest in that machine.Two virtual machines are there.I am using Python binding to query on the hypervisor and extract the VM related information. Here is my simple code: #!/*usr*/local/bin/*python * import libvirt import sys conn = libvirt.openReadOnly(None) if conn == None: print *'Failed to open connection to the

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:

Yes, I am sure because other information pulled are correct. And the same way we have used libvirt APIs to extract other informations at different places. My question is if VM is in shut-off state does it mean running ? IF not, what is the correct state for this VM. I am wondering why the state is 'unsigned char' in virDomainGetInfo, why it could not be 'enum' as it is returning

Hi, all I am trying to get used memory of a running vm using libvirt and then to calculate the memory usage, but with no luck. 1.The used memory returned by virDomainGetInfo is equal to max memory with no virtio balloon driver set. When using virtio balloon driver and setting currentMemory less than memory in the xml, the used memory returned by virDomainGetInfo is nearly equal to

Hi,     Does anyone know where I could view the source code of virt-manager? Because I'm trying to learn how the virt-manager gets the CPU usage of a VM(the graph it displays). I'm trying to make a program using java that gets the CPU usage of a VM in KVM. Anybody have suggestions on where I could start?Thanks regards, Marco

Hi, all, We were running OpenStack with Ubuntu and libvirt 0.9.10. We found that libvirt monitor command not working well. There were a lot of error in libvirtd.log like this 2013-02-07 06:07:39.000+0000: 18112: error : qemuDomainObjBeginJobInternal:773 : Timed out during operation: cannot acquire state change lock We dig into libvirtd by strace and find one of the thread only have the following

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

how do i print the features of a domain from functions that return a domain object? for instance mydomain =?virdomain=libvirt.virConnect.lookupByID(conn,domainid) so mydomain is?virDomainPtr, which is?typedef virDomain * virDomainPtr i am not sure on how to print the domain object features in python, such as name, disk size, etc

Hi, I am trying to connect to a server running esx and collect system metrics like cpu usage, network and disk iops. I am able to establish the connection successfully and obtain VM information such as ids, domain names, config xml etc. But I am unable to collect statistics. I am using the python interface and if I do , conn=libvirt.openAuth(uri, auth, 0) dom-conn.lookupByID(id) // Where id is

Hi , I am using ubuntu host machine and KVM is present as guest in that machine.Two virtual machines are there.I am using Python binding to query on the hypervisor and extract the VM related information.I like to print memory stat of the VM like SWAP_IN , SWAP_OUT,free memory, mem cached etc.So, the code, I have written for this, is : #!/usr/local/bin/python import libvirt import sys conn =

hi experts: I am a freshman of libvirt, I have got a domU's info like: libvirt.open, lookupByID, info. But now I want to use libvirt to get a xen domU 's cpu usage ratio , how can I fulfill it ? I cannot find the API. -------------- next part -------------- An HTML attachment was scrubbed... URL:
