From: Markus Armbruster <[email protected]>
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.
