[Qemu-devel] [PATCH] raw-posix: Fix /dev/cdrom magic on OS X

[Kevin Wolf]

The raw-posix driver has code to provide a /dev/cdrom on OS X even
though it doesn't really exist. However, since commit c66a6157 the real
filename is dismissed after finding it, so opening /dev/cdrom fails.
Put the filename back into the options QDict to make this work again.

On Mac OS X v10.5.8 ppc64 I get:

qemu-system-x86_64: -cdrom /dev/cdrom: could not open disk image
/dev/cdrom: No such file or directory

On ppc I get a crash even without options, seems unrelated though.
