Dear team 

    I am running a centos guest VM  which freezes for every few days . The qemu-kvm on  shows 100% cpu utilization.

    Ping to the guest might work or may not work .Please can you tell me what approach can i take to debug it .

    using "virsh dump" I can dump the core of the  guest vm but I am not sure how to analyse it . 

    Guest Centos VM : "Linux GUESTCentOS70 3.10.0-123.4.4.el7.x86_64 #1 SMP Fri Jul 25 05:07:12 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux"

  "CentOS Linux release 7.0.1406 (Core)"

  1 vcpu and 2 GB ram 

  

Host machine : "Linux HOST 3.10.51-1.el6.elrepo.x86_64 #1 SMP Fri Aug 1 13:14:11 EDT 2014 x86_64 x86_64 x86_64 GNU/Linux"

"CentOS release 6.5 (Final)"

qemu-kvm package used : qemu-kvm-0.12.1.2-2.415.el6_5.10.x86_64

Thanks and regards

I'd say that you should start by updating the OS on both host and guest. Both OSes are heavily outdated, you lack YEARS of updates.
