2017-10-06hbitmap: Rename serialization_granularity to serialization_alignEric Blake
The only client of hbitmap_serialization_granularity() is dirty-bitmap's bdrv_dirty_bitmap_serialization_align(). Keeping the two names consistent is worthwhile, and the shorter name is more representative of what the function returns (the required alignment to be used for start/count of other serialization functions, where violating the alignment causes assertion failures).

2017-09-29tests/docker/run: don't source /etc/profileAlex Bennée
The usual behaviour of /etc/profile is to set the default PATH for users. This runs into problems when we have updated PATH in our dockerfile e.g. to access a cross-compiler in a non-standard location. It shouldn't be needed anyway as we inherit the env from the image when it was setup.

2017-09-29docker: Fix test-mingwFam Zheng
Feature "dtc" is explicitly required by test-mingw, but is not detected by the run script since we switched to archive-source.sh in b7f404201e4. Since it isn't available in the Fedora image which runs this test on patchew, the way we get dtc is still from submodule. archive-source.sh takes care of bundling the submodule files already, so what we need to do is just checking if files are there. Makefile is chosen because it is one that is unlikely to get renamed in the future.

2017-09-26qemu-io: Drop write permissions before read-only reopenKevin Wolf
qemu-io provides a 'reopen' command that allows switching from writable to read-only access. We need to make sure that we don't try to keep write permissions to a BlockBackend that becomes read-only, otherwise things are going to fail. This requires a bdrv_drain() call because otherwise in-flight AIO write requests could issue new internal requests while the permission has already gone away, which would cause assertion failures. Draining the queue doesn't break AIO requests in any new way, bdrv_reopen() would drain it anyway only a few lines later.

A basic set of qemu options is initialised in ./common: export QEMU_OPTIONS="-nodefaults -machine accel=qtest" However, two test cases (172 and 186) overwrite QEMU_OPTIONS and neglect to manually set '-machine accel=qtest'. Add the missing option for 172. 186 probably only copied the code from 172, it doesn't actually need to overwrite QEMU_OPTIONS, so remove that in 186.

2017-09-26tests/boot-sector: Increase timeout to 600 secondsThomas Huth
If QEMU has been compiled with the flags --enable-tcg-interpreter and --enable-debug, the guest is running incredibly slow. The pxe boot test can take up to 400 seconds when testing the pseries ppc64 machine. While we should still look for ways to speed up the test on the pseries machine, it's better to increase the timeout in this test to 600 seconds anyway to allow the test to pass successfully now with this unusal configuration already.
