[2.6.1] maas enlists multiple 'phantom' VMs

[Peter De Sousa]

Hi,

Problem:

When rebooting the node with maas installed maas starts enlisting multiple
machines with unknown origin, with default configuration but with different names.

It seems like a UI defect, but only happens on reboot of the maas machine.

Included maas logs and machines.json in an archive.

Expected:

No VMs to be enlisted randomly

Steps to Reproduce:

1. Install MAAS and MAAS Rackd on a single machine, (Typical Orangebox setup)
2. Create pods on any of the baremetal nodes
3. Create VMs on the baremetal nodes via Juju
4. Powerdown all nodes at the same time (VMs and Baremetal)
5. sudo shutdown now on the MAAS node
6. Power-on maas node
7. Power-on all nodes at the same time, go through any VMs that haven't started and start them
8. Within 5-10 minutes random 'phantom' VMs should start popping up in the MAAS UI

If more information is required please feel free to ask.

Cheers,

Peter

Please don't link to external archive of logs, it's far better to attach individual files to the bug.

Additionally can you please confirm which version of MAAS you're using? Pods on the controllers has had some recent bug fixes

Apologies, attached archive.

Thank you

This is expected. When a POD is registered in MAAS, MAAS will scan for existing VMs and enlists them, similarly with what happens with physical machines.
