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 sum(virVcpuInfo::cpuTime) for a domain is not equal to the virDomainInfo::cpuTime. I...

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

...my bachelor-thesis. Eucalyptus bases on libvirt providing the KVM machines. Part of the thesis is kind of measurement for the uptimes of each instance in the cloud. As Eucalyptus is based on libvirt, i want to know if there is kind of tool already setup for monitoring a vm in terms of uptimes, cputimes and disk i/o. If not, can anyone give me a hint, how i could grep these facts? I found a tool called "virt-top" which monitors the vm, but for me there is to much overhead. Thanks for you support. cheers, Karsten

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

Last week we installed Samba 3.0.20b on one of our servers, worked fine and does it's job well. But today the load was rising due two smbd processes taking up all cputime. While looking for hints on what was going on the logfiles show two types of errors (I don't know at this time if it has anything to do with the load spike): lib/util_sock.c:write_data(554) write_data: write failure in writing to client 0.0.0.0 <http://0.0.0.0>.

...can pick up the output from within the jail. Maybe that's overkill. Perhaps if you run the user's code as an ordinary user and store the answers/results in a directory only root can read that would work (given no local root exploits). Other precautions could include limiting the runtime or cputime for the R session. It might be necessary to limit network access too. Anyone done anything like this? Personally I think there are too many other problems with automated systems like this, particularly that just because a program produces the correct output that makes it a good one. Sure, at the...

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
