microstack.init hangs waiting for 10.20.20.1:5672

[Saul Hazledine]

I installed microstack into a fresh Ubuntu 20.04 following the instructions at:
   https://microstack.run/docs/

Install command:
    sudo snap install microstack --classic --beta

Then I ran microstack.init:
    sudo microstack.init --auto

I got the following output:

2020-05-28 18:55:16,534 - microstack_init - INFO - Configuring networking ...
2020-05-28 18:55:18,421 - microstack_init - INFO - Setting up ipv4 forwarding...

2020-05-28 18:55:19,978 - microstack_init - INFO - Waiting for RabbitMQ to start ...
Waiting for 10.20.20.1:5672

This hung for 20 minutes and so I hit cntrl-C.

My ips after the failed init are:

I'm hitting this bug as well.

I noticed in syslog:
Jul 29 19:11:21 ubuntu-nuc kernel: [794254.328897] audit: type=1400 audit(1596049881.222:4119328): apparmor="DENIED" operation="open" profile="snap.microstack.rabbitmq-server" name="/proc/516115/mountinfo" pid=516115 comm="df" requested_mask="r" denied_mask="r" fsuid=0 ouid=0

This error, https://paste.ubuntu.com/p/sKdMKjBddn/, is repeating in /var/snap/microstack/common/log/rabbitmq/startup_log.

I've tried both the edge and candidate snaps:
  latest/beta: stein 2020-03-05 (196) 412MB classic
  latest/edge: stein 2020-07-09 (206) 389MB -

This is on ubuntu 20.04

I had been running microstack long term and noticed it was unhappy today, trying to recover than encounter this problem.

[Heather Lanigan (hmlanigan)]

Correction, I tried with the edge snap and classic confinement. With demoed and the edge snap, I was able to init.

sudo snap install microstack --edge --dev

[Dmitrii Shcherbakov (dmitriis)]

The instructions got updated at https://microstack.run/ after a significant rework of MicroStack - please follow the new ones.

Note that so far the microstack-support snapd interface work required for strict confinement has not been merged so --devmode is required on install and refresh.

[Justin Lamp (modzilla)]

Problem still occurs on my (vmx enabled) VM. kvm-ok returns working hw accelerated kvm. Installed with sudo snap install microstack --devmode --beta && sudo microstack init --auto --control.

[Justin Lamp (modzilla)]

I'm running 20.04.2 with all updates. But it's the cloud image if that makes a difference.

[Billy Olsen (billy-olsen)]

Justin, can you help provide some additional information? The rabbit logs might be a good start - they're in /var/snap/microstack/common/log/rabbitmq
