[libvirt] Cannot determine QEMU argv syntax with KVM 85

With KVM 85, it is impossible to start domains with libvirtd anymore (I tried both libvirtd 0.6.1 and 0.6.3): # virsh start Cooker error: Failed to start domain Cooker error: internal error Cannot determine QEMU argv syntax /usr/bin/qemu-kvm When I downgrade to KMV 84, everything is working again.
