That has to be fixed before this can be applied. Yes, I have qemu 1.6.1 in my test box, this is probably the reason why I haven't noticed this misbehaviour before. This is a point I wanted to discuss because I'm not sure how to properly achieve this.

Yes, it is. What I want to achieve here is to pre-fill the capabilities cache, by using the function I exported in a previous patch on this series, with the test data. The intent is of course to use only the data from the testsuite and to be independent from the installed QEMU, if any, as you pointed out above. I tried a few different attempts but looks like I'm still missing the point. How can I improve this test to achieve this objective? There is an unit-test I can learn from? Any advice is welcome, I want to fix this.
