[Qemu-devel] [PATCH v4 00/11] Add make check tests for Migration

From: Juan Quintela
Subject: [Qemu-devel] [PATCH v4 00/11] Add make check tests for Migration
Date: Fri, 5 Jan 2018 22:52:35 +0100


In v4:

Based-on: address@hidden

- rebase on top on v4 info_migrate patches
- Tune sleeps to make patches fast
- Create a deprecated test for deprecated commands (i.e. make peterxu happy)
- create migrate_start_postcopy function
- fix naming/sizes between power and x86
- cleanup comments to match code

Please, review.



- No more tests for deprecated parameters. Now I only use
  migrate_set_parameter.  If there is a deprecated command for that,
  we tests it there.
- free "result" string, always good to return memory (Peter found it)
- use the new tcp_port parameter from info migrate.  So we are
  handling well the tcp case.
- lots of code movement around to make everything consistent.
- Several patches already integrated upstream.

Later, Juan.

- to make review easier, I started renaming postcopy-test.c to migration-test.c
- Did cleanups/refactoring there
- Don't use global-qtest anymore
- check that the parameters that we sent got really set
- RFH: comrpress threads tests is not working for some weird reason.  Using the 
same code on command line works.
  still investigating why.


- tcp: after discussions with dave, we ended in conclusion that we
  need to use the 0 port and let the system gives us a free one

  But .... that means that we need to be able to get that port back somehow.
  "info migrate" woring on destination side?

- compression threads.  There is some weird interaction with the test
  hardness and every migration thread get waiting in a different
  semaphore.  Investigating if it is a race/bug/whateverr

- deprecated commands: There was a suggestion to make
  migrate_set_parameter look at the parameter name and test old/new
  depending on something.  Not sure what to do here.

- testing commands: Is there a way to launch qemu and just sent
  qmp/hmp commands without having to really run anything else?

- add test for precopy for unix/tcp
  exec and fd to came, don't know how to test rdma without hardware
- add tests using deprecated interfaces
- add test for xbzrle
  Note to myself, there is no way to set the cache size with 
- Add test for compress threads
  disabled on the series, right now it appears that compression is not working 
at all
- Move postcopy to use new results
  Idea is to move it on top of migration-test.c, but first I want some reviews 
on basic idea

Juan Quintela (11):
  tests: Remove deprecated migration tests commands
  tests: Migration ppc test was missing arguments
  tests: Consolidate accelerators declaration
  tests: Use consistent names and sizes for migration
  tests: Add deprecated commands migration test
  tests: Add migration precopy test
  tests: Add basic migration precopy tcp test
  tests: Add migration xbzrle test
  tests: Create migrate-start-postcopy command
  tests: Adjust sleeps for migration test
  [RFH] tests: Add migration compress threads tests
