Test version:
rhevh-7.1-20150709.0.el7ev.iso
ovirt-node-3.2.3-11.el7.noarch
Red Hat Enterprise Virtualization Manager Version: 3.5.4-1.1.el6ev

Test steps:
1. Install rhevh-7.1-20150709.0.el7ev.iso
2. Register to RHEVM3.5.4.
3. Create VM through nfs storage.
4. Run command "pkill -ABRT -f 'qemu-kvm'" on host.
5. Run  ll /var/log/core/ on host.

Test result:
1. After step5, there is no VM's core dumps in RHEV-H 7.1.

So this issue is not fixed in rhevh-7.1-20150709.0.el7ev.iso. Change the status from ON_QA to ASSIGNED.

Thanks for testing, during my tests upstream I could kill the vm and generate the coredump but downstream I have reproduced your report. Based on that, I have send a new patch, moving the bug to POST.

Test steps:
1. Install rhev-hypervisor7-7.1-20150728.1
2. Register to RHEVM3.5.4.
3. Create VM through nfs storage.
4. Run command "pkill -ABRT -f 'qemu-kvm'" on host.
5. Run  ll /var/log/core/ on host.

Test result:
1. After step5, there is VM's core dumps in /var/log/core/.
# ll /var/log/core/
total 885280
