[Bug 1224193] Re: The helpful suggestions in do-release-upgrade give no love to OpenStack

[Ben Howard]

The problem that I see here is that OpenStack is only part of the cloud
story -- there are others including EC2, Windows Azure, and even
instances on other clouds where SSH is the standard mechanism to access
the host.  In order for this to work, the tool would need to either have
a generic message about security rules or even detect the cloud. The
problem with detecting the cloud, is generally you can only tell which
hypervisor you're on, and even if you figure out that you're in
OpenStack, the instructions might not be applicable for that OpenStack
instance. I think that including  helpful instructions is actually a
sustaintial amount of work.

So while, in prinicple, I agree that this is good idea, I'm just not
sure how to provide information that is accurate; in my opinion bad
information is worse than no infomation. I think that this probably more
of a Cloud papercut than a tool paper cut.

The answer, I think, is that we should include generic instructions on
the Wiki under the Cloud section that generally detail this information.

Title:
  The helpful suggestions in do-release-upgrade give no love to
  OpenStack

Status in “update-manager” package in Ubuntu:
  New

Bug description:
  When running "do-release-upgrade -d" it helpfully launches a backup
  sshd on port 1022 and even more helfully explains how to open-up an
  iptables rule to allow access to it.  However, this may be
  insufficient if the do-release-upgrade command is being executed in an
  OpenStack compute instance because the security group rules for the
  instance/port may have to be updated as well.  While it is likely the
  case that 99 times out of 10 the do-release-upgrade command is being
  executed in bare-iron, that 100th time out of 10 when it is being run
  in an OpenStack compute instance could benefit from some sort of "you
  may need to update security group rules" hint.
