Re: [libvirt] cpu values



As an example to show xm and virsh are reporting the same values:

$ sudo virsh dominfo 0
Id:             0
Name:           Domain-0
UUID:           00000000-0000-0000-0000-000000000000
OS Type:        linux
State:          running
CPU(s):         1
CPU time:       74108.3s
Max memory:     no limit       
Used memory:    763924 kB

$ sudo /usr/sbin/xm vcpu-list                  
Name                              ID VCPUs   CPU State   Time(s) CPU Affinity
Domain-0                           0     0     0   r--   74108.6 any cpu
rhel5_01                           1     0     0   -b-   18642.5 any cpu

$ cat /proc/stat | grep cpu
cpu  414247 1485212 523903 1116332612 350887 0 262 488367
cpu0 414247 1485212 523903 1116332612 350887 0 262 488367

Hi Dan.

Ok, thanks.  I am trying to play around with this and noticed that my code with does use libvirt reports the exact same values as xm.  Either way, I do not see the values even being close.  Is this expected and if so why??

Here is an example of what I am seeing on both:

  I'm aftaid you're confused. xm is the xen direct command line tool
it doesn't use libvirt at all. libvirt command line tool equivalent is
virsh,
