Description John Snow 2015-10-09 13:10:26 EDT
Description of problem:

The tests/ide-test qtest has a flush_test that races during the qemu-kvm build process. It may fail on sufficiently fast hardware.

Version-Release number of selected component (if applicable):


How reproducible:

Depends on your hardware. If it is sufficiently fast, it can be close to 100%.

Steps to Reproduce:
1. Attempt to build RPM
2. Build process fails while running make check

Or, if you build the source manually from the exploded tree:
1. configure --target-list="x86_64-softmmu"
2. make
3. make check

Actual results:

RPM build process fails due to test failure.

Expected results:

RPM build process reliably succeeds.

Additional info:

The flush test relies on the "qemu-io" HMP command to pause execution of the flush command in order to perform the test reliably without races. The qemu-io HMP command was not introduced until upstream qemu 1.6.0, so the test as it exists downstream races, leading to occasional failures.
