Hi Daniel, Thanks a lot for your reply. We have mounted all the cgoup controllers at "/dev/cgroup_<controller>" as mentioned below. ls /dev/ | grep cgroup cgroup_cpu cgroup_cpuacct cgroup_cpuset cgroup_mem On further debugging we dound that the "VCPU" directories are not being created for our domains and hence the comamnd "cpu-stats

Hi Daniel, Thanks for your immidiate reply. The starting of virtual guest was ok on our machine. We are facing this issue while executing the "cpu-stats <domain name>" command. I have collected the debug logs as you suggested and attaching the same. <<libvirt_testing_starting_VG.log >> --> Log collected while starting the virtual guest

Software in use: *Source hypervisor:* *Qemu:* stable-2.12 branch *Libvirt*: v3.2-maint branch *OS*: CentOS 6 *Destination hypervisor: **Qemu:* stable-2.12 branch *Libvirt*: v4.9-maint branch *OS*: CentOS 7 I'm experiencing an intermittent live migration hang of a virtual machine (KVM) with a ceph RBD volume attached. At the high level what I see is that when this does happen, the virtual

When using a vtsc, hvm_set_guest_time changes hvm_vcpu.stime_offset, which is used in the vcpu time structure to calculate the tsc_timestamp, so after updating stime_offset we need to propagate the change to vcpu_time in order for the guest to get the right time if using the PV clock. This was not done correctly, since in context_switch update_vcpu_system_time was called before vmx_do_resume,

Hi, We have upgraded the libvirt version from libvirt-1.0.5 to libvirt-1.0.6-1 on our linux machine. After this upgrade "virsh cpu-stats <domain>" command is not working on our HardWare. *virsh # cpu-stats test error: Failed to retrieve CPU statistics for domain 'test' error: internal error error accessing cgroup cpuacct for vcpu* ** *# cat /proc/cgroups #subsys_name

Hi Eric, Thanks for your valuable time and comments. >> Are you sure cpuacct was mounted prior to libvirtd starting? Yes, we are mounting cpuacct before starting the libvirtd daemon. >> Libvirt won't mount cgroups; Yes, Agree. >>it only uses what was mounted at the time it was started. But we are mounting it well before it is started. We are facing the issue only while

Hello, I'm trying to use libvirt as a non-root user to obtain statistics on the CPU usage by VMs using the Python API. I'm performing basically the following steps: import libvirt conn = libvirt.openReadOnly(None) dom = conn.lookupByUUIDString('268e38ea-1bc7-41e4-c19e-8eff682e58e4') dom.getCPUStats(True, 0) However, they result in the following error: libvir: QEMU Driver

Respin of the paravirt clock patch series. On the host side the kvm paravirt clock is made compatible with the xen clock. On the guest side some xen code has been factored out into a separate source file shared by both kvm and xen clock implementations. This time it should work ok for kvm smp guests ;) cheers, Gerd

paravirt clock source patches, next round, with a bunch of changes in the host code according to Avi's review comments and some minor code tweaks. cheers, Gerd

paravirt clock source patches, next round. There is now a pvclock-abi.h file with the structs and some longish comments in it and everybody is switched over to use the stuff in there. Some minor tweaks after super-fast review by Jeremy. The queue is on top of the kvm git tree. The first two patches should have no kvm dependencies and should apply to linus tree just fine. cheers, Gerd

Hello, I want to emit a structured log entry (in YAML) for every request that hits my Rails app. For example, an entry in this log would look something like: --- SYSTEM_TIME: 0.0166666666666667 USER_TIME: 0.0999999999999996 DB_TIME: 0.00247621536254883 REAL_TIME: 0.091976 STATUS_CODE: 500 SESSION_ID: 64ad46a8841c66bbf64e93335cedc50d REQUEST_ID: 32d6a42f-da58-43e2-ab27-09d3e2a775cb

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?

I have another problem. As in java bindings there is no way to obtain cpu stats I decided to use a python script. It gives me, for the guest domain, cpu time, system time and user time. Now, what does it mean cpu time? I though that it could be the overall cpu time given to this vm...but the sum doesn't add up: user_time+system_time != cpu_time. As I would need to get a %cpu usage, like
