Undefined method 'physical_device' in preseed_networking_setup

Support

Hi,

I try to provision a vm machine with an alias/virtual Interface like eth0:1.
So far so good. After the first build and the final Callback to Foreman I
get an Exception in the foreman log so that the "wget" command to finish
build cancels.

> ActionView::Template::Error: The snippet 'preseed_networking_setup'
threw an error: undefined method 'physical_device' for Nic::Base::Jail
(Nic::Managed)

`method_missing'

I stop build mode manuall directly in foreman. When I try to restart the
build I got that Message from foreman in the webgui as popup before I can
force the build.

Failure parsing Preseed default finish DemoVM : The snippet
'preseed_networking_setup' threw an error: undefined method
'physical_device' for Nic::Base::Jail (Nic::Managed).

In the Snippet "preseed_networking_setup" I found this

<% @host.managed_interfaces.each do |interface| %>
<% next if !interface.managed? || interface.subnet.nil? ||
interface.primary -%>
<% subnet = interface.subnet -%>
<% virtual = interface.virtual? -%>
<% dhcp = subnet.nil? ? false : subnet.dhcp_boot_mode? -%>
real=ip -o link | grep &lt;%= interface.mac -%&gt; | awk &#39;{print $2;}&#39; | sed s/:$//
<% if virtual -%>
real=echo &lt;%= interface.identifier -%&gt; | sed s/&lt;%=* interface.physical_device* -%&gt;/$real/
<% end -%>

But what's the correct Method for interface.physical_device?

Thanks for help,

Tom

It should probably be interface.attached_to, it was renamed back in
Foreman 1.7.0. If it works for you, please do send a fix to
https://github.com/theforeman/community-templates/blob/develop/snippets/preseed_networking_setup.erb.

FWIW, this got fixed in https://github.com/theforeman/community-templates/pull/351

Perfect!
But there are still some other errors. Will report @github

Thanks.
