Plugins

Hi,

I'm currently running into an issue where existing hosts submit facts and do puppetruns fine, however, new hosts are not added into Foreman.
I think this error might be a result of installing the foreman-xen plugin, though I'm not certain.
The reason why I say this is that I have another bug filed ([[http://projects.theforeman.org/issues/6110]]) that complains about:

undefined method `[]' for nil:NilClass

This same message appears in my production.log below.
I also can't seem to revert back to* not using the plugin*.
When I remove the plugin via yum, bounce httpd,foreman-proxy,foreman, and puppetmaster, I receive the following error when going to the 'About' page (to go and view plugin info):

ActiveRecord::SubclassNotFound
The single-table inheritance mechanism failed to locate the subclass: 'ForemanXen::Xenserver'. This error is raised because the column 'type' is reserved for storing the class in case of inheritance. Please rename this column if you didn't intend it to be used for storing the inheritance class or overwrite ComputeResource.inheritance_column to use another column for that information.
