[Animesh] Sebastian you have brought up a  good point dependency on QA team from Citrix is
an issue for the project. This was raised in the past as well and Alex's proposal [1] few
months back using CI was in my opinion is the optimal solution. Why? Because CloudStack is
a huge project and one single person cannot have the full knowledge to safely review all the
code and certainly cannot scale, which CI and automation can address

Keeping master stable is something no one would argue against and my point would match the
original proposal from Alex. May be we can  have a staging branch for master and then merging
the commit only after they have passed CI into master. The proposal got derailed and delayed
because as called out at that time community does not want to work with a process that has
a dependency on infrastructure that is not controlled by community. David and I are working
to get the hardware from Citrix into ACS infra. 

The approach for fixing issues in release branch first and master later is not practical as
we may miss out commits not made into master and future release regressing without the fixes.
Also as the release goes into hardening cycle there will be a number of fixes which will not
be allowed in release branch but need to be fixes for future, they should all go in master.
Master is the catch all default branch and in my opinion should get fixes first.

[Animesh] Completely Agreed

[Animesh] I have already expressed my opinion in favor of CI

[Animesh] I  followed up the release process as established by Chip for 4.2 and 4.3 release
for which I was the RM and frankly I did not feel it that way other than the pain of multiple
RCs. Folks may not like it but I am entitled to my opinion and I do feel part of the issues
for 4.4 were self- inflicted because of pre mature code freeze and too early cherry picking.
