38If the backing file is smaller than the snapshot, then the backing file will be
39resized to be the same size as the snapshot. If the snapshot is smaller than
40the backing file, the backing file will not be truncated. If you want the
41backing file to match the size of the smaller snapshot, you can safely truncate
42it yourself once the commit operation successfully completes.

187Remove host block device. The result is that guest generated IO is no longer
188submitted against the host device underlying the disk. Once a drive has
189been deleted, the QEMU Block layer returns -EIO which results in IO
190errors in the guest for applications that are reading/writing to the device.
