CentOS virt - Apr 2016 - version(qemu-kvm) with parallel port support

Whether  there  is a version of the qemu-kvm with support for parallel
port  (passthrough).  I  need  parallel  port for Windows VM (security
dongle LPT).

I use
on one host
# /usr/libexec/qemu-kvm -version
QEMU emulator version 2.3.0 (qemu-kvm-ev-2.3.0-31.el7_2.10.1)

another host
 /usr/libexec/qemu-kvm -version
QEMU emulator version 1.5.3 (qemu-kvm-1.5.3-105.el7_2.3)


Both versions do not support parallel port and generate error:

qemu-kvm: -device isa-parallel,chardev=char parallel 0,id=parallel
0: 'isa-parallel' is not a valid device model name

This says that parallel dongles don't work well in any hypervisor:

Yes on CentOS / RHEL this is not supported, you can open a RFE about it on
bugzilla.redhat.com.
