2015-04-08qcow2: Fix header update with overridden backing fileKevin Wolf
In recent qemu versions, it is possible to override the backing file name and format that is stored in the image file with values given at runtime. In such cases, the temporary override could end up in the image header if the qcow2 header was updated, while obviously correct behaviour would be to leave the on-disk backing file path/format unchanged. Fix this and add a test case for it.

2015-02-16qemu-io: Remove "growable" optionMax Reitz
Remove "growable" option from the "open" command and from the qemu-io command line. qemu-io is about to be converted to BlockBackend which will make sure that no request exceeds the image size, so the only way to keep "growable" would be to use BlockBackend if it is not given and to directly access the BDS if it is. qemu-io is a debugging tool, therefore removing a rarely used option will have only a very small impact, if any. There was only one qemu-iotest which used the option; since it is not critical, this patch just removes it.

2015-02-16qemu-iotests: Add 093 for IO throttlingFam Zheng
This case utilizes qemu-io command "aio_{read,write} -q" to verify the effectiveness of IO throttling options. It's implemented by driving the vm timer from qtest protocol, so the throttling timers are signaled with determinied time duration. Then we verify the completed IO requests are within 10% error of bps and iops limits. "null" protocol is used as the disk backend so that no actual disk IO is performed on host, this will make the blockstats much more deterministic. Both "null-aio" and "null-co" are covered, which is also a simple cross validation test for the driver code.

2014-12-10block: Don't probe for unknown backing file formatKevin Wolf
If a qcow2 image specifies a backing file format that doesn't correspond to any format driver that qemu knows, we shouldn't fall back to probing, but simply error out. Not looking up the backing file driver in bdrv_open_backing_file(), but just filling in the "driver" option if it isn't there moves us closer to the goal of having everything in QDict options and gets us the error handling of bdrv_open(), which correctly refuses unknown drivers.

2014-09-12block: round up file size to nearest sectorHu Tao
Currently the file size requested by user is rounded down to nearest sector, causing the actual file size could be a bit less than the size user requested.
