Currently the qemu-iotest framework is focused on the x86 platform. The suite should be usable by other platforms as well.
To enable multi-platform usage, this patch set enhances the framework scripts to address this. By using the default machine
type of the platform one can add specific output files if it deviates from the default. Secondly, single test cases can
be adjusted as well when e.g. devices have different names or are not supported at all. 

Mao Chuan Li (9):
  qemu-iotests: run qemu with -nodefaults
  qemu-iotests: qemu machine type support
  qemu-iotests: add core_pattern access functions
  qemu-iotests: fix test 039
  qemu-iotests: s390x: fix test 071
  qemu-iotests: s390x: fix test 087
  qemu-iotests: s390x: fix test 041
  qemu-iotests: s390x: fix test 055
  qemu-iotests: s390x: fix test 051

This patch fixes an io test suite issue that was introduced with the
commit c88930a6866e74953e931ae749781e98e486e5c8 'qemu-char: Permit only
a single "stdio" character device'. The option supresses the creation of
default devices.

This patch adds qemu machine type support to the io test suite. Based on
the qemu default machine type the reference output file can now vary
from the default to a machine specific output file if necessary. That
shall allow all platforms to use this test suite.

To prevent core dump file generation, the new functions allow to clear
and restore the /proc/sys/kernel/core_pattern definition.

For successful execution of case 039, core dump need be
disabled. Just running "ulimit -c 0" command is not enough when the
/proc/sys/kernel/core_pattern indicates to pipe the dump to another
application. So we must erase the pattern in addition to the ulimit
command.

All the commands run by this test case are suitable for the s390 platform.
But the commands in this case produce slightly different output compared
to the default x86_64 platform.

There is no such device 'ide-cd' defined on the s390 platform, so
test_medium_not_found() test is skipped.

The tests for device type "ide_cd" are skipped for the s390 platform.
The default device id of hard disk on the s390 platform differs to that
of the x86 platform. A new variable device_id is defined and "virtio0"
set for the s390 platform. A s390 platform specific output file is also
needed.

Do you really want the user to be root to execute the iotests?

Hi,

I cannot think of a way; on the other hand, I don't think disabling the 
core dump is necessary either. Simply filtering out '(core dumped) ' is 
not pretty but still suffices for me (we can put that into a filter 
function in common.filter and if other people see other messages for a 
core dump, they can expand that list).

If we really want to disable core dumps, we should change qemu-io not to 
use abort() on -c abort (raise(SIGKILL) seems like a good alternative to 
me); or, alternatively, introduce a new command 'kill' which then does 
raise(SIGKILL) so we don't have to break compatibility.

Mao,

you can skip this a and the previous (3/9) patch from the series, please have a look to the patch
Max has posted to solve the issue.

To me, the main difference between the current test output and the new 
s390-specific seems to be lines about CD and floppy disk; due to patch 
1, they are gone from x86 as well, though. Therefore, we don't need 
special s390 output, but need to apply the changes directly to 071.out 
and 087.out.

Furthermore, after patch 1, tests 067 and 091 fail for me on x86, too. I 
don't know why 091 fails, but 067 fails because CD and floppy are 
missing from the block-query result and the DEVICE_TRAY_MOVED events are 
missing from QMP output in general (which is completely fine, we just 
need to adjust the reference output accordingly).

Ah, I know why 091 failed. I forgot -c writethrough and ran it in /tmp. 
My bad. So it's only 067 that needs fixing.

perfect, that's fully in our interest.

We have two more test 060 and 082 that fail with the following difference to
the reference output. We analyzed it and it turns out that the size on disk is
file system dependent. In our case it ran on a s390/ext3. Thus we think comparing
the size on disk should be filtered. With other file system like ext4 or tmpfs we
get also 196K. We don't want to enforce a specific file system to be used.    

060         - output mismatch (see 060.out.bad)

_img_info already filters the size out. The reason why it isn't used
here is that it also filters all of the format specific information out.
We could probably make that part optional and then reuse it here.

I'm not sure if this is the better solution then because one has to use a
new global variable to provide the parameter:

I was thinking along the lines of this (which leaves most of
the filtering in place, it just doesn't strip the format-specific
information):
