Subject RE: [ACS42][QA]Test Plan for "Affinity / Anti-affinity Rules"
Date Mon, 08 Apr 2013 21:23:01 GMT
Thank you for the review comments Prachi.

For the test cases relating to UpdateVMAffinityGroup() , I will add the testcases where the
Vm cannot be started on the last host on which it was running before being stopped.

For live migration test case , I will update the expected result as per the review comments.

-Thanks
Sangeetha

Hi Sangeetha,

The test plan looks fine. A few comments

1) UpdateVMAffinityGroup API - We should add to the testcases, the scenario where an already
existing VM say on host1, is  updated to have affinity group A1 that asks to avoid host1.

In this case, the VM cannot restart on host1, but should start on some other host within or
outside cluster.

2) And #66 Live migration - Live migration of Vms which are associated with anti-affinity
group failing - The live migration will still succeed since it is Admin's choice to use host2
even if it is not suitable.
We just indicate if the host is suitable or not, but CS should not stop Admin from live migrating.


Prasanna,
Affinity Group Processing is a pre-planning step. It will set the scope for the deployment
planners, there is no conflict between the planner strategies and affinity groups. These are
separate steps of deployment planning.


Thanks,
Prachi

There are planning decisions that are controlled in the global settings that do similar things
as do affinity groups.
UserConcentration and UserDispersion are two kinds of allocators that affect planning decision
very similar to affinity and anti-affinity.
Some cases surrounding the conflicts arising from these settings would need to be added. Rest
of the tests look good given that the scope of the feature is only a single anti-affinity
processor at this time.
