On closer examination it turned out to be a mismatch error (missing "'"
in a distant part of the spec).

Now it passes the syntax check, but I get a "permission denied" error
on the /dev/input/... line:

Error starting domain: internal error: process exited while connecting
to monitor: 2017-04-30T23:08:12.041484Z qemu-system-x86_64: -object
input-linux,id=kbd,evdev=/dev/input/event3,grab_all=on: Could not open
'/dev/input/event3': Permission denied

Any thoughts? virt-manager requires root so I don't see where this is
coming from.
