Funny you should mention that. I¹m not the RM obviously, but Daan asked me
if I could have a fresh look at the list of blockers and criticals. If you
want, consider me a temporary junior administrative assistant to the
release manager ;-). What¹s a chore for Daan is a good way for me to learn
more cloudstack!

Here¹s this afternoon's blockers against 4.4 ordered by creation date:

* Bug          CLOUDSTACK-6602
  [UI]         createNetworkACL API action param value passed incorrectly
  Assignee:    Jessica Wang
  Created:     5/8/14 5:55
  Updated:     6/3/14 13:08
  Leo¹s evaluation: seems like a blocker;
               _probably_ simple fix if you know the javascript?
  Leo¹s suggestion: fix for 4.4

* Bug          CLOUDSTACK-6779
  [OVS]        Expunging VM (deleting vif) deletes all the rules from ovs
               bridge flow table
  Assignee:    Murali Reddy
  Created:     5/27/14 12:49
  Updated:     6/6/14 12:43
  Leo¹s evaluation: seems like a blocker, work is in progress
  Leo¹s suggestion: fix for 4.4

  Updated:     6/8/14 21:28
  Leo¹s evaluation: stalled on info from tester
  Leo¹s suggestion: downgrade to major

* Test         CLOUDSTACK-6861
  [Automation] Test case test_01_snapshot_root_disk during mount
  Assignee:    **Unassigned**
  Created:     6/9/14 3:50
  Updated:     6/9/14 3:55
  Leo¹s evaluation: looks like it could be a test environment issue
               instead of a code issue?
  Leo¹s suggestion: downgrade to major

* Test         CLOUDSTACK-6863
  [Automation] test_09_delete_detached_volume failing inconsistently with
               during simulator run
  Assignee:    **Unassigned**
  Created:     6/9/14 4:03
  Updated:     6/9/14 4:04
  Leo¹s evaluation: seems like a blocker, looks scary
  Leo¹s suggestion: fix for 4.4, mark as bug, not test

* Test         CLOUDSTACK-6862
  [Automation] Test case
               faling during BVT
  Assignee:    **Unassigned**
  Created:     6/9/14 3:55
  Updated:     6/10/14 21:01
  Leo¹s evaluation: test for unfinished new feature is failing
  Leo¹s suggestion: if not easy to fix, defer feature to 4.5

I was going to give my suggestions to Daan to try and make a call on, but I
guess it¹s better if that can be done by y¹all, right here.

Note a lot of these are very recent coming out of ongoing QA, so I imagine
this list is still to grow before it shrinks.

Next, here¹s a bunch of older critical issues against 4.4:

As you can see, as far as I understand (which is not very farŠ), most of
these older issues are definitely serious. In other words, I think most of
them definitely deserve to be considered critical bugs, they¹re not
particularly mis-triaged. But, they¹re very specific / difficult to
reproduce / limited to a specific combination of components, so they
should perhaps not hold up a release, given where cloudstack is at right
now. For many of them, that¹s the same choice that was made when baking
the 4.3 release. It¹d obviously be great to not have to bump them again,
but, given this release is so late, it seems a reasonable choice.

Then there¹s another bucket of issues related to something called ³vmsync²
which need some follow up from someone that understands that stuff.

CLOUDSTACK-6063 also deserves a highlight. AIUI this was a dirty/quick fix
for 4.3 that should have received a proper fix in then-master now-4.4. I
didn¹t find yet whether it did.

I think tomorrow I¹m digging through the criticals that have seen updates
after may 1st, of which there are currently **68**. Comparing bug creation
rate with bug resolution rate, there will never be a 4.4 release if all
those have to be fixedŠso I imagine the only available approach is to
defer a lot of _those_ to 4.5, too :-/.

Hope this helps! Cheers,
