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: https://bugzilla.redhat.com/show_bug.cgi?id=1623692 -- LF
