The --aio=MODE option enables Linux AIO or Windows overlapped I/O. The #ifdef CONFIG_LINUX_AIO was a layering violation that also prevented Windows overlapped I/O from being used. Now that raw-posix.c prints an error when Linux AIO has not been compiled in, we can unconditionally compile the option into qemu-nbd. After this patch qemu-nbd --aio=native works on Windows.

raw-posix.c silently ignores BDRV_O_NATIVE_AIO if libaio is unavailable. It is confusing when aio=native performance is identical to aio=threads because the binary was accidentally built without libaio. Print a deprecation warning if -drive aio=native is used with a binary that does not support libaio. There are probably users using aio=native who would be inconvenienced if QEMU suddenly refused to start their guests. In the future this will become an error.

2015-10-16util - add automated ID generation utilityJeff Cody2-0/+45
Multiple sub-systems in QEMU may find it useful to generate IDs for objects that a user may reference via QMP or HMP. This patch presents a standardized way to do it, so that automatic ID generation follows the same rules. This patch enforces the following rules when generating an ID: 1.) Guarantee no collisions with a user-specified ID 2.) Identify the sub-system the ID belongs to 3.) Guarantee of uniqueness 4.) Spoiling predictability, to avoid creating an assumption of object ordering and parsing (i.e., we don't want users to think they can guess the next ID based on prior behavior). The scheme for this is as follows (no spaces): # subsys D RR Reserved char --| | | | Subsystem String ----| | | Unique number (64-bit) --| | Two-digit random number ---| For example, a generated node-name for the block sub-system may look like this: #block076 The caller of id_generate() is responsible for freeing the generated node name string with g_free().

2015-10-16block: Add and use bdrv_replace_in_backing_chain()Kevin Wolf4-26/+49
This cleans up the mess we left behind in the mirror code after the previous patch. Instead of using bdrv_swap(), just change pointers. The interface change of the mirror job that callers must consider is that after job completion, their local BDS pointers still point to the same node now. qemu-img must change its code accordingly (which makes it easier to understand); the other callers stays unchanged because after completion they don't do anything with the BDS, but just with the job, and the job is still owned by the source BDS.

2015-10-16blockjob: Store device name at job creationKevin Wolf3-9/+17
Some block jobs change the block device graph on completion. This means that the device that owns the job and originally was addressed with its device name may no longer be what the corresponding BlockBackend points to. Previously, the effects of bdrv_swap() ensured that the job was (at least partially) transferred to the target image. Events that contain the device name could still use bdrv_get_device_name(job->bs) and get the same result. After removing bdrv_swap(), this won't work any more. Instead, save the device name at job creation and use that copy for QMP events and anything else identifying the job.

2015-10-16block: Implement bdrv_append() without bdrv_swap()Kevin Wolf2-29/+85
Remember all parent nodes and just change the pointers there instead of swapping the contents of the BlockDriverState. Handling of snapshot=on must be moved further down in bdrv_open() because *pbs (which is the bs pointer in the BlockBackend) must already be set before bdrv_append() is called. Otherwise bdrv_append() changes the BB's pointer to the temporary snapshot, but bdrv_open() overwrites it with the read-only original image. We also need to be careful to update callers as the interface changes (becomes less insane): Previously, the meaning of the two parameters was inverted when bdrv_append() returns. Now any BDS pointers keep pointing to the same node.
