Luiz Capitulino 8be7e7e4c7 qemu-option: qemu_opts_create(): use error_set()
This commit converts qemu_opts_create() from qerror_report() to
error_set().

Currently, most calls to qemu_opts_create() can't fail, so most
callers don't need any changes.

The two cases where code checks for qemu_opts_create() erros are:

 1. Initialization code in vl.c. All of them print their own
    error messages directly to stderr, no need to pass the Error
    object

 2. The functions opts_parse(), qemu_opts_from_qdict() and
    qemu_chr_parse_compat() make use of the error information and
    they can be called from HMP or QMP. In this case, to allow for
    incremental conversion, we propagate the error up using
    qerror_report_err(), which keeps the QError semantics

Stefan Hajnoczi c83c66c3b5 block: add 'speed' optional parameter to block-stream
Allow streaming operations to be started with an initial speed limit.
This eliminates the window of time between starting streaming and
issuing block-job-set-speed.  Users should use the new optional 'speed'
parameter instead so that speed limits are in effect immediately when
the job starts.

Stefan Hajnoczi fd7f8c6537 block: use Error mechanism instead of -errno for block_job_create()
The block job API uses -errno return values internally and we convert
these to Error in the QMP functions.  This is ugly because the Error
should be created at the point where we still have all the relevant
information.  More importantly, it is hard to add new error cases to
this case since we quickly run out of -errno values without losing
information.

Go ahead and use Error directly and don't convert later.

Stefan Hajnoczi e88774971c block: handle -EBUSY in bdrv_commit_all()
Monitor operations that manipulate image files must not execute while a
background job (like image streaming) is in progress.  This prevents
corruptions from happening when two pieces of code are manipulating the
image file without knowledge of each other.

The monitor "commit" command raises QERR_DEVICE_IN_USE when
bdrv_commit() returns -EBUSY but "commit all" has no error handling.
This is easy to fix, although note that we do not deliver a detailed
error about which device was busy in the "commit all" case.

Jeff Cody 8802d1fdd4 qapi: Introduce blockdev-group-snapshot-sync command
This is a QAPI/QMP only command to take a snapshot of a group of
devices. This is similar to the blockdev-snapshot-sync command, except
blockdev-group-snapshot-sync accepts a list devices, filenames, and
formats.

It is attempted to keep the snapshot of the group atomic; if the
creation or open of any of the new snapshots fails, then all of
the new snapshots are abandoned, and the name of the snapshot image
that failed is returned.  The failure case should not interrupt
any operations.

Rather than use bdrv_close() along with a subsequent bdrv_open() to
perform the pivot, the original image is never closed and the new
image is placed 'in front' of the original image via manipulation
of the BlockDriverState fields.  Thus, once the new snapshot image
has been successfully created, there are no more failure points
before pivoting to the new snapshot.

This allows the group of disks to remain consistent with each other,
even across snapshot failures.

Stefan Hajnoczi aa398a5c3a blockdev: make image streaming safe across hotplug
Unplugging a storage interface like virtio-blk causes the host block
device to be deleted too.  Long-running operations like block migration
must take a DriveInfo reference to prevent the BlockDriverState from
being freed.  For image streaming we can do the same thing.

Note that it is not possible to acquire/release the drive reference in
block.c where the block job functions live because
drive_get_ref()/drive_put_ref() are blockdev.c functions.  Calling them
from block.c would be a layering violation - tools like qemu-img don't
even link against blockdev.c.

Luiz Capitulino 6106e2492f qapi: Convert blockdev_snapshot_sync
Unfortunately, this conversion required an additional change.

In the old QMP command, the 'snapshot-file' argument is specified as
optional. The idea is to take the snapshot internally if 'snapshot-file'
is not passed. However, internal snapshots are not supported yet so
the command returns a MissingParamater error if 'snapshot-file' is not
passed. Which makes the argument actually required and will cause
compatibility breakage if we change that in the future.

To fix this the QAPI converted blockdev_snapshot_sync command makes the
'snapshot-file' argument required. Again, in practice it's actually required,
so this is not incompatible.

If we do implement internal snapshots someday, we'll need a new argument
for it.

Note that this discussion doesn't affect HMP.

Paolo Bonzini 025ccaa7f9 block: add eject request callback
Recent versions of udev always keep the tray locked so that the kernel
can observe "eject request" events (aka tray button presses) even on
discs that aren't mounted.  Add support for these events in the ATAPI
and SCSI cd drive device models.

To let management cope with the behavior of udev, an event should also
be added for "tray opened/closed".  This way, after issuing an "eject"
command, management can poll until the guests actually reacts to the
command.  They can then issue the "change" command after the tray has been
opened, or try with "eject -f" after a (configurable?) timeout.  However,
with this patch and the corresponding support in the device models,
at least it is possible to do a manual two-step eject+change sequence.

Markus Armbruster 2c6942fa7b block: Clean up remaining users of "removable"
BlockDriverState member removable is a confused mess.  It is true when
an ide-cd, scsi-cd or floppy qdev is attached, or when the
BlockDriverState was created with -drive if={floppy,sd} or -drive
if={ide,scsi,xen,none},media=cdrom ("created removable"), except when
an ide-hd, scsi-hd, scsi-generic or virtio-blk qdev is attached.

Three users remain:

1. eject_device(), via bdrv_is_removable() uses it to determine
   whether a block device can eject media.

2. bdrv_info() is monitor command "info block".  QMP documentation
   says "true if the device is removable, false otherwise".  From the
   monitor user's point of view, the only sensible interpretation of
   "is removable" is "can eject media with monitor commands eject and
   change".

A block device can eject media unless a device is attached that
doesn't support it.  Switch the two users over to new
bdrv_dev_has_removable_media() that returns exactly that.

3. bdrv_getlength() uses to suppress its length cache when media can
   change (see commit 46a4e4e6).  Media change is either monitor
   command change (updates the length cache), monitor command eject
   (doesn't update the length cache, easily fixable), or physical
   media change (invalidates length cache, not so easily fixable).

I'm refraining from improving anything here, because this series is
long enough already.  Instead, I simply switch it over to
bdrv_dev_has_removable_media() as well.

This changes the behavior of the length cache and of monitor commands
eject and change in two cases:

a. drive not created removable, no device attached

   The commit makes the drive removable, and defeats the length cache.

   Example: -drive if=none

b. drive created removable, but the attached drive is non-removable,
   and doesn't call bdrv_set_removable(..., 0) (most devices don't)

   The commit makes the drive non-removable, and enables the length
   cache.

   Example: -drive if=xen,media=cdrom -M xenpv

   The other non-removable devices that don't call
   bdrv_set_removable() can't currently use a drive created removable,
   either because they aren't qdevified, or because they lack a drive
   property.  Won't stay that way.
