The only failing test is this one:

parameters::remove-interface#test_0004_should remove interface [test/functional/compute_attribute_test.rb:651]:
--- expected
+++ actual
@@ -1 +1,3 @@
-""
+"Could not remove interface:
+  Error: undefined method `has_key?' for nil:NilClass
+"

Not sure why it doesn't work with Libvirt compute resource, need to take a look.

Thanks, @stejskalleos, I guess this should wait until the same logic was removed from the core?

Regarding failing test, please see inline, that should fix it.

Correct, this is for the 3.16 release. I just want to make sure everything is ready so we can merge the PR right after the branching.
