Thanks to pointing to that bug report. 

I downgraded from 

qemu-kvm-0.12.1.2-2.506.el6_10.1.x86_64
qemu-img-0.12.1.2-2.506.el6_10.1.x86_64 

to 

qemu-img-0.12.1.2-2.503.el6_9.6.x86_64
qemu-kvm-0.12.1.2-2.503.el6_9.6.x86_64

and booted into

kernel-2.6.32-754.3.5.el6.x86_64

unfortunately no positiv effect.

The system/host/workstation crashes/panics immediately after 
starting a guest system (EL6) with virsh start guest-name.


BTW upstream bug report:
