	Even it is not very useful, users may create images of size 0. Without the special option CONFIG_ZERO_MALLOC, qemu_mallocz aborts execution when it is told to allocate 0 bytes, so avoid this kind of call.

2010-05-17	block: Avoid unchecked casts for AIOCBs	Kevin Wolf	1	-1/+1
	Use container_of for one direction and &acb->common for the other one. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2010-05-03	block: Open the underlying image file in generic code	Kevin Wolf	1	-20/+9
	Format drivers shouldn't need to bother with things like file names, but rather just get an open BlockDriverState for the underlying protocol. This patch introduces this behaviour for bdrv_open implementation. For protocols which need to access the filename to open their file/device/connection/... a new callback bdrv_file_open is introduced which doesn't get an underlying file opened. For now, also some of the more obscure formats use bdrv_file_open because they open() the file themselves instead of using the block.c functions. They need to be fixed in later patches.

2010-01-08	block/vdi: allow disk sizes not multiple of block size	François Revol	1	-2/+5
	The disk image I created from my old laptop disk with VBoxManage internalcommand converthd obviously was not a multiple of 1MB as when created from scratch. This fixes QEMU refusing it. We still require the size to be a multiple of sector size though. It then boots correctly. Allow opening VDI images with size not multiple of 1MB (as when converted from a raw disk).

2009-10-04	Check availability of uuid header / library	Stefan Weil	1	-2/+2
	If available, the Universally Unique Identifier library is used by the vdi block driver. Other parts of QEMU (vl.c) could also use it. Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2009-08-27	block/vdi.c: Fix several bugs	Stefan Weil	1	-4/+9
	* The code for option '-static' was wrong, so image creation always created static images. * Static images created with qemu-img did not set header entry blocks_allocated. * The size of the block map must be rounded to the next multiple of SECTOR_SIZE, otherwise the block map is only read partially for block map sizes which are not a multiple of SECTOR_SIZE.

2009-08-10	Add new block driver for the VDI format (only aio supported)	Stefan Weil	1	-0/+951
	This is a new block driver written from scratch to support the VDI format in QEMU. VDI is the native format used by Innotek / SUN VirtualBox. Latest changes: * stripped down version (code for synchronous operations and experimental code removed) * don't open VDI snapshot images (with uuid_link or uuid_parent) * modified vdi_aio_cancel Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> Message-Id:
