The upper_mem field of the Multiboot information struct doesn't really contain the RAM size - 1 MB like we used to calculate it, but only the memory from 1 MB up to the first (upper) memory hole. In order to correctly retrieve this information, the multiboot ROM now looks at the mmap it creates anyway and tries to find the size of contiguous usable memory from 1 MB. Drop the multiboot.c definition of lower_mem and upper_mem because both are queried at runtime now.

When the BIOS returns ebx = 0, the current entry is still valid and needs to be included in the Multiboot memory map. Fixing this meant that using bx as the entry index doesn't work any more because it's 0 on the last entry (and it was SeaBIOS-specific anyway), so the whole loop had to change a bit and should be more generic as a result (ebx can be an arbitrary continuation number now, and the entry size returned by the BIOS is used instead of hard-coding 20 bytes).

length is a ram_addr_t, so RAM_ADDR_FMT must be used instead of %ld. This fixes a recently introduced regression for w64 builds. Using RAM_ADDR_FMT also changes decimal output to sedecimal. This is good here because length and block->length should both use the same base in the error message.

.has_zero_init defaults to 1 for all formats and protocols. this is a dangerous default since this means that all new added drivers need to manually overwrite it to 0 if they do not ensure that a device is zero initialized after bdrv_create(). if a driver needs to explicitly set this value to 1 its easier to verify the correctness in the review process. during review of the existing drivers it turned out that ssh and gluster had a wrong default of 1. both protocols support host_devices as backend which are not by default zero initialized. this wrong assumption will lead to possible corruption if qemu-img convert is used to write to such a backend. vpc and vmdk also defaulted to 1 altough they support fixed respectively flat extends. this has to be addresses in separate patches. both formats as well as the mentioned ssh and gluster are turned to the default of 0 with this patch for safety. a similar problem with the wrong default existed for iscsi most likely because the driver developer did oversee the default value of 1.

When creating image with backing file, the driver tries to calculate the relative path from created image file to backing file, but the path computation is incorrect. e.g.: $ qemu-img create -f vmdk -b vmdk-data-disk.vmdk vmdk-data-snapshot1 Formatting 'vmdk-data-snapshot1', fmt=vmdk size=10737418240 backing_file='vmdk-data-disk.vmdk' compat6=off zeroed_grain=off $ qemu-img info vmdk-data-snapshot1 image: vmdk-data-snapshot1 file format: vmdk virtual size: 10G (10737418240 bytes) disk size: 12K -> backing file: disk.vmdk The common part in file names, "vmdk-data-", is incorrectly forgotten by relative_path(). As the VMDK specification has no restriction on parentNameHint to be relative path, we simply remove this by using the backing_file option.

GlusterFS volumes can be backed by block devices, in which case bdrv_create() doesn't make sure that the image is zeroed out. It is currently not possibly to detect whether a given image is backed by a file or a block device, and incorrectly assuming that it is zeroed corrupts images during qemu-img convert, so let's err on the side of caution and always return 0.

This patch adds a transactional version of the drive-backup QMP command. It allows atomic snapshots of multiple drives along with automatic cleanup if there is a failure to start one of the backup jobs. Note that QMP events are emitted for block job completion/cancellation and the block job will be listed by query-block-jobs. @device: the name of the device whose writes should be mirrored. @target: the target of the new image. If the file exists, or if it is a device, the existing file/device will be used as the new destination. If it does not exist, a new file will be created. @format: #optional the format of the new destination, default is to probe if @mode is 'existing', else the format of the source @mode: #optional whether and how QEMU should create a new image, default is 'absolute-paths'. @speed: #optional the maximum speed, in bytes per second @on-source-error: #optional the action to take on an error on the source, default 'report'. 'stop' and 'enospc' can only be used if the block device supports io-status (see BlockInfo). @on-target-error: #optional the action to take on an error on the target, default 'report' (no limitations, since this applies to a different block device than @device).
