Centos 7 Guest vm freezing

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 CentOS70 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 XXX-BServer01 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-
Thanks and regards

CentOS 7.0 and CentOS 6.5? Why so old? I'm rather surprised that it only
freezes every few days... KVM/QEMU was in early stages for RHEL/CentOS 5
and 6. I think you at least go to CentOS 6.10 for the host, but even this
seems terribly old as a software baseline to use for a production server...

In any case, not a CentOS developers discussion... more a question for
somebody who still supports these old versions. Even Red Hat has declared
6.5 end of extended update support some time ago...

I guess you should send this message to the centos list, not centos-devel.
There may be more people there to help you in this case.
