Description David Kutálek 2016-04-13 08:57:40 UTC 
Description of problem:
This happens for me when resuming paused Windows 10 guest in which 
I run CDK, ie. Vagrant controlled Virtualbox machine with RHEL 7.2.

So this is nested virtualization setup:
L0 = this RHEL 7.2 host
L1 = Windows 10 Enterprise
L2 = RHEL 7.2 with Virtualbox 5.0.16 as hypervisor (controlled by Vagrant)

It happened to me several times, not sure whether always.

Factor could be that between pause/resume of L1 I also suspended L0
(it is my notebook I carry around).

Can try to reproduce again if needed - what more debug data would you like?

Version-Release number of selected component:
qemu-kvm-rhev-2.1.2-23.el7_1.6

                         ^^^^^^^

This appears to be the RHEL-7.1 version, not RHEL-7.2.
Please update qemu, try again and report back.

High chance to be a bug 1128992 duplicate,
should be fixed in qemu-kvm-rhev-2.3.0-20.el7 and newer.

Thanks for hint, I updated the package and crash occurs no more.

The problem was hidden in having updated RHEL 7.2 
mixed with non updated Openstack source.
