I came across a bug that the command line generated for passthrough of the host parallel port /dev/parport0 by libvirt for QEMU is incorrect. It currently produces: -chardev tty,id=charparallel0,path=/dev/parport0 -device isa-parallel,chardev=charparallel0,id=parallel0 The first parameter is "tty". It sould be "parport". If I launch qemu with -chardev parport,... it works as expected. I have already filled a bug report ( https://bugzilla.redhat.com/show_bug.cgi?id=823879 ), the topic was already on the list some months ago: https://www.redhat.com/archives/libvirt-users/2011-September/msg00095.html Signed-off-by: Eric Blake <eblake@redhat.com>
