A future patch will be using a 'name':{dictionary} entry in the QAPI schema to specify a default value for an optional argument (see previous commit message for more details why); but existing use of inline nested structs conflicts with that goal. This patch fixes one of only two commands relying on nested types, by breaking the nesting into an explicit type; it means that the type is now boxed instead of unboxed in C code, but the QMP wire format is unaffected by this change. Prefer the safer g_new0() while making the conversion.

The image field in BlockDeviceInfo should never be null, however bdrv_block_device_info() is not filling it in. This makes the 'info block -n -v' command crash QEMU. The proper solution is probably to move the relevant code from bdrv_query_info() to bdrv_block_device_info(), but since we're too close to the release for that this simpler workaround solves the crash.

qemu-io should behave like a guest, therefore it should use BlockBackend to access the block layer. There are a couple of places where that is infeasible: First, the bdrv_debug_* functions could theoretically be mirrored in the BlockBackend, but since these are functions internal to the block layer, they should not be visible externally (qemu-io as a test tool is exempt from this). Second, bdrv_get_info() and bdrv_get_specific_info() work on a single BDS alone, therefore they should stay BDS-specific. Third, bdrv_is_allocated() mainly works on a single BDS as well. Some data may be passed through from the BDS's file (if sectors which are apparently allocated in the file are not really allocated there but just zero). [Fixed conflicts around block_acct_start() usage from Fam Zheng's "qemu-io: Account IO by aio_read and aio_write" commit. Use BlockBackend and blk_get_stats() instead of BlockDriverState. --Stefan] Signed-off-by: NMax Reitz <mreitz@redhat.com> Reviewed-by: NEric Blake <eblake@redhat.com> Message-id: 1423162705-32065-14-git-send-email-mreitz@redhat.com Signed-off-by: NStefan Hajnoczi <stefanha@redhat.com>

由 Jeff Cody 提交于
On some image chains, QEMU may not always be able to resolve the filenames properly, when updating the backing file of an image after a block job. For instance, certain relative pathnames may fail, or drives may have been specified originally by file descriptor (e.g. /dev/fd/???), or a relative protocol pathname may have been used. In these instances, QEMU may lack the information to be able to make the correct choice, but the user or management layer most likely does have that knowledge. With this extension to the block-stream api, the user is able to change the backing file of the active layer as part of the block-stream operation. This allows the change to be 'safe', in the sense that if the attempt to write the active image metadata fails, then the block-stream operation returns failure, without disrupting the guest. If a backing file string is not specified in the command, the backing file string to use is determined in the same manner as it was previously.

this patch tries to optimize zero write requests by automatically using bdrv_write_zeroes if it is supported by the format. This significantly speeds up file system initialization and should speed zero write test used to test backend storage performance.

'kdump-snappy': kdump-compressed format, with snappy-compressed Without 'format' being set, it is same as 'elf'. And if non-elf format is specified, paging and filter is not allowed. Note: 1. The kdump-compressed format is readable only with the crash utility and makedumpfile, and it can be smaller than the ELF format because of the compression support. 2.
