[Qemu-devel] [kvm-unit-tests PATCH v6 0/3] run_tests: support concurrent test execution

[Peter Xu <peterx@redhat.com>]

v6:
- some tunes on how to rm/mv logs/logs.old [Drew]
- fix errno to 2 when param parse fail [Drew]
- add one more patch to fix *) case errno [Drew]
  (please either take/squash/... this one)
- comment fix again [Drew]

v5:
- add "/" at start/end of line where proper [Drew]
- remove useless newline in Makefile [Drew]
- don't check "mv" since it won't fail [Drew]
- avoid using '"s in (( )) [Drew]
- comment fix [Drew]

v4:
- add .gitignore for logs/ [Drew]
- instead of create globals.bash, renaming function.bash into
  common.bash, put globals inside [Drew]
- instead of removing logs/ directly when start run_tests, move it
  into logs.old so we at least have the last time result cached [Drew]
- s/ut_/unittest_/ through the whole series [Drew]
- remove unittest_log_summary var [Drew]
- remove radim's s-b in patch 2 since it does not suite [Drew]
- tiny fix on the usage lines [Drew]
- use bash arithmetic where proper [Drew]
- remove ut_in_parallel since not used [Drew]

v3:
- better handling for ctrl-c during run_tests.sh [Radim]

v2:
- patch 1: do per-test logging in all cases
- patch 2: throw away task.bash, instead, take Radim's suggestion to
  use jobs

run_tests.sh is getting slower. Maybe it's time to let it run faster.
An obvious issue is that, we were running the tests sequentially in
the past.

This series provides another new "-j" parameter. "-j 8" means we run
the tests on 8 task queues. That'll fasten the script a lot. A very
quick test of mine shows 3x speed boost with 8 task queues.

Please review, thanks.

  run_tests: fix errno for param parsing
  run_tests: put logs into per-test file
  run_tests: allow run tests in parallel
