similar to: CPU Usage and Memory Usage for VM and Host

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

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 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

Sorry but I misunderstood your last post completely :-D but now I tried what you said, using the CVS version. I also dumped the "ret" value from virXen_getdomaininfo. The output was simple: ret=1, domain_flags=0 (right after XEN_GETDOMAININFO_FLAGS!!!). Sadly I don''t have much time to dig deeper but it seems to me that this happens very seldom or sometimes not at all (hard

[PATCH 3/4] modify account_system_time() to add cputime to cpustat->guest i= f we are running a VCPU. We add this cputime to cpustat->user instead of cpustat->system because this part of KVM code is in fact user code although= it is executed in the kernel. We duplicate VCPU time between guest and user to allow an unmodified "top(1)" to display correct value. A modified

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

sched_sedf.c used o have its own mechanism for producing tracing-alike kind of information (domain block, wakeup, etc.). Nowadays, with an even not so high number of pCPUs/vCPUs, just trying to enable this makes the serial console completely unusable, produces tons of very hard to parse and interpreet logging and can easily livelock Dom0. Moreover, pretty much the same result this is struggling to

to whomever that was. i deleted your email but I think below does what you want. as always, there's probably some improvement that could be done. whether it's ? minor or major, i'm not sure ? also, 3 things:? ? A)there are some Inf's in the output because of division by zero but I wasn't sure how you wanted to handle that. B) it also assumes that an n=1

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

I was getting vCPU use time outside of guest with libvirt-python API, and them calculate utilization with (cpuTime2 - cpuTime1) / (t2 - t1).

I have a small S4 class for which I've written a page grouping many of the accessors and replacement functions together. I would be interested in people comments on the approach I've taken. The code has a couple of decisions for which I could imagine alternatives. First, even simple get/set operations on class elements are wrapped in functions. I suppose I could just use myinstance at
