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...

...he 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 can't find the libvirt API call to get system info, such as total memory in the system, free memory, total disk space, available disk space, etc. There is virDomainInfo which shows memory total and free about a particular VM, I guess I can use active/inactive domain list and then use virDomainInfo on each of the VM's, but that does not give me hypervisor stats. I am wondering if I will have to enable SNMP and use that to get hypervisors stats. I am creating t...

Hi All, I am new to libvirt. Please explain about the units (which is bytes or KB or MB) and uses of DomainJobInfo and DomainBlockInfo methods. Like getMemRemaining(), getDataRemaining() etc. Using libvirt version is libvirt-0.5.1. Thank you Regards, Rathidevi

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 domain unsigned long long cpuTim...

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.

Hi, this is a mostly done attempt to switch to ocaml-libvirt, embedding the latest version of it from git. This way, it is possible to improve the way v2v connects to libvirt for both input, and output modules, and interacts with libvirt (e.g. no more virsh calls needed in virt-v2v). As side effect, virt-v2v now requires libvirt, as keeping it optional would create too much burden. I could not
