similar to: [help] how can I use libvirt to get cpu usage ratio ?

Hi, ALL, I just look for the class and method to use blockcopy in libvirt-java on this page: http://libvirt.org/sources/java/javadoc/ However, I can not find out. Libvirt-java Support blockcopy ? Thanks. Best Regards, Star Guo

Hi Peter, Can you say a little bit more about what you're doing exactly with the information you're exposing and how? unfortunately, I don't have a concrete proposal in mind right now. That's in part because I don't quite understand the use case, but also because it's really hard to expose this kind of information in a way that both avoids breaking application with new

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

Dear friends maybe someone can help this freshman at R, by tell step by step how can I read files from windows 2003-2007 to Rgui, I had tried all, no see solution?? [[alternative HTML version deleted]]

Hi all, I am a freshman of R,but I am interested in it! Those days,I am learning pages on NIST,with url http://www.itl.nist.gov/div898/handbook/eda/section3/probplot.htm, I am meeting a problem about probability plot and I don't know how to plot a data set with R. Could somebody tell me the answer,and a example is the best! I will look forward to your answer. Thank you very much.

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

I am a freshman when it comes to RoR, and I haven''t been able to figure this out. I need to figure out how to query records in my database using form check boxes (or radio buttons) then display them in that same instance. What would this look? I have been told that just putting a question mark after here, :conditions => field = ?, but what would the argument look like? Thanks in

Hello, I am a student. Now I need to know EXACTLY about How Samba Works. I have the source on samba-3.0.28a, but it's too many for me to read and understand 'cause I was a freshman.

Can anybody help me to run the Elasticnet package of R to build some model, i am a freshman to R language , when i use the Elasticnet package to my data, it always reture a error, but i can't settle that problem. I consider if there is any constrant of the data to that package? Can anyone help me to run the elasticnet and check my data as you convenient? I put the data in attachment. Thank

Hi all, I try to get vm cpu stat by function "virDomainGetCPUStats", when the vm Cpu usage is 100%, I can see from the vm shell by "top", when the info Get by the "virDomainGetCPUStats" show only the "cpu_time" increased, "user_time" and "system_time" was not changed at all. Is that correct ? How can I get the vm cpu usage?

Hi, at first i have to mention, that i am an freshman in Linux. I am working with it since half a year and still trying to get the basic-knowledge. Nevertheless I've wanted to install Diablo, my favourite game, on Wine. But when I start the setup.exe with the 'Wine-Windows-Emulator' an dchoose the installation-path, only an video-sequence starts, then it returnes to desktop. When I

Hi, Weeks ago, I developed my app under ubuntu-11.10 (kernel 3.0) with lilbvirt-0.9.10. In my code , I used virDomainGetCPUStats to query cpu usage info of domains, and it worked well. However, today, I port my code to ubuntu-10.04.4 (kernel 2.6.32) with libvirt-0.9.10, I find the function virDomainGetCPUStats can't work and complains "this function is not supported by the connection

Hi, I am facing issue with the calls getCPUStats and getMemoryStats. Please find the error below. AttributeError: 'module' object has no attribute 'VIR_NODE_CPU_STATS_ALL_CPUS' >>> print con.getCPUStats(2, None, 0, 0) Traceback (most recent call last): File "<stdin>", line 1, in <module> File

Hi, everyone I'm using libvirt and resort to virDomainGetCPUStats for cpu usage by one domain. In my system, Ubuntu-11.10 64bit with 2 cores and Qemu Hyperviser, this function returns something like this: virTypedParameter[0] { field: "cpu_time" type: 4 value.ul 51640610899 } virTypedParameter[1] {

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 usage of

Hi Jean-Marc, We're exposing the opus_internal_flags data structure so that we can access the value assigned to prevSignalType. Here's a snippet of our code: error = opus_encoder_get_internal_flags(vad->opus, &internalflags); if (error != OPUS_OK) { return OPUSVAD_OPUS_ERROR; } cur_signal_type = internalflags.prevSignalType; if

Hi, everyone I'm writing application using libvirt and I need call virDomainGetCPUStats to get domain cpu stats . I learn from API reference that this function has to be called when domain is running. So my question is if there is an atomic way to test the domain's state and get its stats? Or, it's ok to call this function when domain is not active, but caller just gets error

Hi Peter, There's two main issues with a patch like the one you're proposing. First, the data is only valid when SILK is being used and is essentially undefined in CELT mode. The second issue is that by exposing internals, it makes it impossible to improve these algorithms since it would break API compatibility. I'm not fundamentally against trying to expose some information, but

hi, everyone. I find an 'interesting' thing involving virDomainGetCPUStats(). I call it for cpu usage consumed by a domain and get a array of virTypedParameter. My system is 2-core and hyperviser return 1 parameter per cpu. So the contents of the array is like this. virTypedParameter[0] { .fiedl = "cpu_time" .type = 4 .value.ul = 51640610899
