The classes that set tests for the block-stream command with discard
option on are inherited from the existent classes in the 030 file.
Some QMP commands do not have the optional 'discard' argument because
the WRITE permission is not being granted when the filter is inserted.
For instance, it is tr
The discard option for block-stream command requires insertion of the
filter to write into the backing chain. In that case, the job will not
resume by device name. So, the node name is specified.

After node graph changes, we may not be able to resume_drive by device
name (backing files are not recursively searched). So, lets allow to
resume by node-name. Set constant name for breakpoints, to avoid
introducing extra parameters.

Hello everyone!
The given feature discards blocks with copy-on-read operation while the

command allows dropping a block in the backing chain after it has been copied

TestCase.assertEquals() is deprecated since Python 2.7. Recent Python
versions print a warning when the function is called, which makes test

Commit 40dce4ee6 "scsi-disk: fix rerror/werror=ignore" introduced a
bug which causes qemu to crash with the assertion error below if the
host file or disk returns an error:
qemu-system-x86_64: hw/scsi/scsi-bus.c:1374: scsi_req_complete:
Assertion `req->status == -1
time.clock() is deprecated since Python 3.3. Current Python versions
warn that the function will be removed in Python 3.8, and those warnings
make the test case 118 fail.
Replace it with the Timeout mechanism that is compatible with both
Python 2 and 3, and makes the code even a little nicer.
