[virt-tools-list] [PATCH v2 2/6] connection: support checking for a list of features

[marcandre.lureau at redhat.com]

From: Marc-André Lureau <marcandre.lureau at redhat.com>

Make check_support() accept a list of features.

This will let tests have more complex conditions on the features they
require.
