What features of kernel are required to support virDomainGetCPUStats?
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

virDomainGetCPUStats missing in Java API bindings ?
Hi All
I am trying to get the performance statistics for KVM using Java bindings.
I found some api's for getting memory stats but not able to find any for
cpu stats.
I found virDomainGetCPUStats which look like its going to return cpu stats
for a VM at http://libvirt.org/html/libvirt-libvirt.html and
http://libvirt.org/hvsupport.html .
I couldnt find these methods getting called from java

What does cpu_time returned by virDomainGetCPUStats mean?
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

Can you please retry with libvirt 1.1.4? There have been some bug fixes
in this area, and it's not worth debugging old versions if the new
version is already fixed.

problem when get the vm cpu stat
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?

fuse in libivrt-lxc
Hi,
I created an LXC domain via libvirt (on Fedora 20), but when I'm trying to
mount a FUSE filesystem, like sshfs, I'm getting a following error:
$ sshfs 172.30.15.2:/<mntdir> /<mntpoint>
fuse: device not found, try 'modprobe fuse' first
I see that there's no /dev/fuse device. Is there a way to make it work? Can
I get it working via libvirt domain xml file

What's the precision of the domain cpu stats?
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

getCPUStats of a domain by a non-root user - libvirtError: Requested operation is not valid: cgroup CPUACCT controller is not mounted
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:

Is this Race Condition?
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

Libvirt Java API to get CPU usage of VM (KVM)
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

Help needed regarding "virsh cpu-stats test_vm"

We are implementing feature called CPU separation in the platform. So,
guest VMs will have dedicated cores allocated using cgroups (cgroups
hierachy related VMs managed by libvirt).
virsh cpu-stats command is not working in our platform :

[SPAM] The Infamous "Device 0 (vif) could not be connected. Hotplug scripts not working."
When I start my domU, I get the infamous and UNINFORMATIVE! error message:
"Device 0 (vif) could not be connected. Hotplug scripts not working."
What could be the cause?
There are strange things occuring. When I boot the host, I can start
zero, one or two VM before it happens (most often zero), and then no
other VM may be started successfully.
It fails the same whether I try to boot

libvirt v1.0.2 fails to boot LXC container, but v1.0.0 works
Hello.
tl;dr = v1.0.0 can boot my LXC containers, v.1.0.1 and v.1.0.2 fails.
Paraphrased error message: "lxcContainerMountProcFuse:616 : Failed to
mount ..../meminfo"
I'd like to know if my host is misconfigured, or my domains, or
... why 1.0.2 and 1.0.1 are not working for me.
I've been using libvirt for a while to manage QEMU instances. I
have experimented with lxc.
