> PR 1647 [1] proposes dropping support for Ubuntu 12.04 from 4.9.2.0+.  The primary motivation
for its removal is that the age of its libvirt and qemu versions greatly complicate maintenance
of the KVM integration.  However, Ubuntu 12.04 will be supported until April 2017 [2]. What
would be the impact to our user community of removing support for Ubuntu 12.04 before its
EOL in April 2017?  If we don’t drop support for it in 4.x, would it be acceptable to drop
support for it in 5.0.0 which is currently scheduled for release at the end of 2016 [3]?

The PR was supposed to go into 4.9 already, it just took way to long to get merged. So that's
why it would now go into 4.9.2

> If we do chose to drop support for Ubuntu 12.04 in 4.x, I propose that we remove it in
4.10.0.0 rather than 4.9.2.0.  First, it is reasonable for users to expect that upgrading
between patch releases (i.e. 4.9.x.x -> 4.9.x+1.x) would not require system changes.  Dropping
a distribution would violate such an expectation.  Second, 4.9 is an LTS branch.  Therefore,
maintaining 12.04 support in 4.9 would provide LTS users with support for Ubuntu 12.04 until
May 2018 — well after its EOL.  Does this approach seem reasonable if we elect drop Ubuntu
12.04 in 4.x?

Again, this PR had to be merged earlier, not later. It's just very difficult packaging wise
to keep supporting 12.04 and 16.04 at the same time.

The Qemu and libvirt versions in 12.04 are truly ancient. I doubt anybody is running stock
12.04 with CloudStack 4.8 right now for example.

The Ubuntu 12.04 debate has been popping up multiple times in the last year.

This PR has been open way to long, that's imho the main problem here.

I'm in favor of dropping 12.04, should have been done in 4.9 already and not wait any longer.
