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:
