[abrt] new crash was detected
Description of problem:
The virtual instance (qemu-kvm process) disappears after virsh suspend & resume operations.
qemu
Version-Release number of selected component (if applicable):
qemu-kvm-0.12.1.2-2.160.el6.x86_64
qemu-kvm-debuginfo-0.12.1.2-2.160.el6.x86_64
qemu-kvm-tools-0.12.1.2-2.160.el6.x86_64
libvirt-0.8.8-1.el6.x86_64
libvirt-client-0.8.8-1.el6.x86_64
libvirt-devel-0.8.8-1.el6.x86_64
How reproducible:
It is very easy to reproduce especially with a non-virtio base image. A non-virtio image somehow can not be reproduced every time.
Steps to Reproduce:
1. virsh suspend instance_id
2. wait for a little while
3. virsh resume instance_id
Actual results:
That instance (qemu-kvm process) is gone!!!
Expected results:
The instance should continue to work
Additional info:

We need to ship our product based on RHEL6.1, and this is a real severe problem
which will block our shipment, it will be nice to fix it as soon as possible,
otherwise we have to switch to other OS or xen.
this issue is probably duplicate bz703554

Hi Red Hat ,
We tried with upstream qemu-kvm ( qemu-kvm-0.15.0) and not able to reproduce this issue. However I am not able to figureout the patch which fixed this issue.
Any update on this issue ? Will this be included in RHEL6.2 cycle ?
Thanks
Vasant

HI Kevin,
(In reply to comment #20)

> 6.2 packages. Can you give it a try?
I see that bz698537 is verified against qemu-kvm-0.12.1.2-2.172.el6. I have downloaded these package from RHN site. Let me give a try.
Will get back with result soon.
Thanks
Vasant

Hi Kevin,
Tried with qemu-kvm-0.12.1.2-2.172.el6 and its working fine for me. Can we assume this version will be included in RHEL6.2 ?
Thanks
Vasant
