vpc: Add support for Fixed Disk type

The Virtual Hard Disk Image Format Specification allows for three
types of hard disk formats, Fixed, Dynamic, and Differencing. Qemu
currently only supports Dynamic disks. This patch adds support for
the Fixed Disk format....

vpc: Round up image size during fixed image creation

The geometry calculation algorithm from the VHD spec rounds the image
size down if it doesn't exactly match a geometry. During image
conversion, this causes the image to be truncated. For dynamic images,...

qcow2: Update whole header at once

In order to switch the backing file, qcow2 issues multiple write
requests that only changed a part of the image header. Any failure after
the first one would leave the header in an corrupted state. With this
patch, the whole header is written at once, so we can't fail in the...

qcow2: Keep unknown header extension when rewriting header

If we want header extensions to work as compatible extensions, we can't
destroy yet unknown header extensions when rewriting the header (e.g.
for changing the backing file). Save all unknown header extensions in a...

sheepdog: fix co_recv coroutine context

The co_recv coroutine has two things that will try to enter it:

1. The select(2) read callback on the sheepdog socket.
  2. The aio_add_request() blocking operations, including a coroutine
     mutex.

This patch fixes it by setting NULL to co_recv before sending data....

qed: replace is_write with flags field

Per-request attributes like read/write are currently implemented as bool
fields in the QEDAIOCB struct. This becomes unwiedly as the number of
attributes grows. For example, the qed_aio_setup() function would have...

qed: add .bdrv_co_write_zeroes() support

Zero writes are a dedicated interface for writing regions of zeroes into
the image file. If clusters are not yet allocated it is possible to use
an efficient metadata representation which keeps the image file compact...

iSCSI: add configuration variables for iSCSI

This patch adds configuration variables for iSCSI to set
initiator-name to use when logging in to the target,
which type of header-digest to negotiate with the target
and username and password for CHAP authentication....

qcow: Use bdrv functions to replace file operation

Since common file operation functions lack of error detection and use
much more I/O syscalls, so change them to bdrv series functions and
reduce I/O request.
