local provider lxc and kvm deploys appear stuck pending, waiting for template/image download

[mahmoh]

Clean Trusty install of Juju from ppa:juju/stable appears to fail, manually adding a lxc template appears to fix the problem.

Symptom:

$ juju status
environment: local
machines:
  "0":
    agent-state: started
    agent-version: 1.20.13.1
    dns-name: localhost
    instance-id: localhost
    series: trusty
    state-server-member-status: has-vote
  "1":
    agent-state: pending
    instance-id: m-local-machine-1
    series: trusty
    hardware: arch=amd64
services:
  juju-gui:
    charm: cs:trusty/juju-gui-16
    exposed: false
    units:
      juju-gui/0:
        agent-state: pending
        machine: "1"

^appears to stay in that state forever; if I execute the following (from another bug), it now appears to work:

$ sudo lxc-create -n juju-trusty-lxc-template -t ubuntu-cloud -f /var/lib/juju/containers/juju-trusty-lxc-template/lxc.conf -- --debug --userdata /var/lib/juju/containers/juju-trusty-lxc-template/cloud-init --hostid juju-trusty-lxc-template -r trusty

$ juju status

Question: minimally this is a documentation or process issue if I wasn't instruction to either wait [for the template to download fully the first time] or provided with an error [that the template was missing].

The first time juju creates a container, it will create the template. The time is largely network dependant. How long did you wait? do you have fast network to download the OS image? wonder if Juju did get stuck because I have never waited more than 10 minutes to build the templates.

[mahmoh (mahmoh)]

There is no indication to the user that there will be a significant delay, minimally a message like "Please be patient while LXC is creating the initial template ..." or similar if not a progress bar.

When I created the template manually it took between 5-10m. I also tried with precise and either didn't wait long enough or it didn't work but I created it manually in the end. I'll have to cleanup and retry.

In the meantime, do we make this bug a messaging bug until I can attempt a clean setup reproduction? Thank you.

This also applies to KVM (container: kvm), I had to wait for what seemed like ages but knowing the problem I checked lsof and my traffic stats to finally notice that /tmp/ files were being downloaded for images. Without a status message it just seems as though everything's broken to new users.
