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
Akshar

Both OSes are heavily outdated, you lack YEARS of updates. ??? Regards ??? Manuel -------------- next part -------------- An HTML attachment was scrubbed...

Hi Thanks for the reply We have seen the same guest VM freezing on vmware ESXi machine also , so we were interested in know in the internal condition of the guest vm when the freeze happened How can we analyse the core file generated by "virsh dump " Thanks and regards Akshar On Wed, Jan 9, 2019 at 1:58 PM Manuel Wolfshant <wolfy at nobugconsulting.ro> wrote:> On 1/9/19 10:24 AM, Akshar Kanak wrote: > > Dear team > I am running a centos guest VM which freezes for every few days .
