    list = (ListView)view.findViewById(R.id.lista_Inicial);
    Host = new String[] { "Host1 ", "Host2", "Host3"};
    Descricao = new String[] { "Estado do Host", "Estado do Host", "Host" };

Many Android components and objects need a Context to work, meaning you need to tell what's going on for these components and newly created objects.

A tip is in the onAttach method of your Fragment , you reference an instance of your activity, like this:

SuaActivity mActivity;
@Override
public void onAttach(Activity activity) {  
    super.onAttach(activity);
    mActivity = (SuaActivity) getActivity();
}

Now, when you're going to set anything in your snippet that needs a Context , you simply (using your Dialog):

...
final Dialog dialog = new Dialog(mActivity);
...

use only:

final Dialog dialog = new Dialog(getActivity());
