qemu-iotests: Test I/O in a single drive from a throttling group iotest 093 contains a test that creates a throttling group with several drives and performs I/O in all of them. This patch adds a new test that creates a similar setup but only performs I/O in one of the drives at the same time. This is useful to test that the round robin algorithm is behaving properly in these scenarios, and is specifically written using the regression introduced in 27ccdd52598290f0f8b58be56e as an example.

qemu-iotests: Add 093 for IO throttling 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.
