Bug Description

Fresh install of MAAS 2.0 beta4 on Xenial is not able to add machines due to unavailable and unknown power types.

The following maas cli command fails:
maas _maas machines create architecture=amd64/generic mac_addresses=ec:b1:d7:7f:ff:a4 hostname=azurill power_parameters_power_address=192.168.246.111 autodetect_nodegroup=1 power_type=ipmi power_parameters_power_user=maas power_parameters_power_pass=quality_first power_parameters_power_driver=LAN_2_0
{"power_parameters": ["Unknown parameter(s): power_address, power_driver, power_user, power_pass."]}

Enlisting the machine by booting it, also results in a node entry that has no Power type selections available.

Was your Rack Controller connected ? I see this in the logs:

2016-05-13 01:12:33+0000 [Uninitialized] Region not available: Connection was refused by other side: 111: Connection refused. (While requesting RPC info at b'http://localhost:5240/MAAS/rpc/').

This would cause you to see no power parameters available.

This does not affect the UI, as the UI provides the correct information. Looking into the API now.

This is a cache issue provided you are accessing MAAS via apache2 instead of accessing it direcctly at port 5240.

What is the best way to confirm the Rack Controller is connected? I did notice those messages but could not find anything glaring that indicated continued connection issues.

I ended up re-booting the hardware the MAAS server was running on, after which power type selection was available.
