[one-users] 回复： Host resources statistical error!

[David]

Hi,
   I am using OpenNebula version is 3.2.1。
   The following strange usage values still exist in this release version， and there is no virtual machine of the same name.
   
   I saw a virtual machine used memory value is 4G, but It takes up belongs to host mem_usage value is 1G， this is very strange.
   
   What is the solution In this version ?  thanks!


Regards.

Hi,

What OpenNebula version are you using? There was a bug in older versions that sometimes caused these strange usage values. It was triggered when several VMs had the same name.

    AMEM（19.4G） greater than TMEM（16G）， this phenomenon often appear in other environment.
   It leads to obtain XML data was wrong.

        <USED_CPU>0</USED_CPU>
         <RUNNING_VMS>0</RUNNING_VMS>
    </HOST_SHARE>
   MEM_USAGE become negative ， at the same time the virtual machine scheduling is affected, also we call to XML-RPC have an effect.
   What was the reason for the cases above ? 
 
regards!
David.
