From: Markus Armbruster <arm...@redhat.com> Such devices have always been unavailable and omitted from the list of available devices shown by device_add help. Until commit 18b6dad silently broke the former, setting up nasty traps for unwary users, like this one:
$ qemu-system-x86_64 -nodefaults -monitor stdio -display none QEMU 1.6.50 monitor - type 'help' for more information (qemu) device_add apic Segmentation fault (core dumped) I call that a regression. Fix it.
