Hmm, this is strange. I made some modifications for the tests
in 0001 of the series (qcow2: introduce compression type feature).

Among the other test related changes, the patch contains the hunk:

+++ b/tests/qemu-iotests/common.filter
@@ -152,7 +152,8 @@ _filter_img_create()
          -e "s# refcount_bits=[0-9]\\+##g" \
          -e "s# key-secret=[a-zA-Z0-9]\\+##g" \
          -e "s# iter-time=[0-9]\\+##g" \
-        -e "s# force_size=\\(on\\|off\\)##g"
+        -e "s# force_size=\\(on\\|off\\)##g" \
+        -e "s# compression_type=[a-zA-Z0-9]\\+##g"
  }

which has to filter out "compression_type" on image creation.

But you say that you can see the "compression_type" on the image creation.
May be the patch wasn't fully applied? Or the test related modification 
were omitted?

I've just re-based the series on top of:

Author: Peter Maydell <peter.maydell@linaro.org>

and run the tests with 'make check-block'

and got the following:

Not run: 071 099 184 220 259 267
Some cases not run in: 030 040 041
Passed all 113 iotests

May be I do something wrong?
