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
