I've got a spec written up at http://wiki.qemu.org/Features/QCFG.
Initial code is in my QAPI tree.
One question about a small detail on this wiki page:
typedef struct BlockdevConfig {
char * file;
struct BlockdevConfig * backing_file;
struct BlockdevConfig * next;
} BlockdevConfig;
What is the 'next' pointer used for,
This is a standard part of QAPI. All types get a next pointer added
such that we can support lists of complex types.
are you going to store a list of
all -blockdev options used? And why isn't it a QLIST or something?
Two reasons. QLIST requires another type for the head of the list which
would complicate things overall. Second is that these types are part of
the libqmp interface and I didn't want to force qemu-queue on any
consumer of libqmp.
