37 Commit changes to the disk images (if -snapshot is used) or backing files.
38 If the backing file is smaller than the snapshot, then the backing file will be
39 resized to be the same size as the snapshot. If the snapshot is smaller than
40 the backing file, the backing file will not be truncated. If you want the
41 backing file to match the size of the smaller snapshot, you can safely truncate
42 it yourself once the commit operation successfully completes.

74 resizes image files, it can not resize block devices like LVM volumes.

189 Remove host block device. The result is that guest generated IO is no longer
190 submitted against the host device underlying the disk. Once a drive has
191 been deleted, the QEMU Block layer returns -EIO which results in IO
192 errors in the guest for applications that are reading/writing to the device.

194 actions (drive options rerror, werror).
