The 301 HTTP status is because _DNVM_DEFAULT_FEED="https://nuget.org/api/v2" gets redirected to https://www.nuget.org/api/v2. Should probably just add in the www

Adding www in the URL doesn't seem to help

$ dnvm install stable
Default stable feed (https://nuget.org/api/v2) is being overridden by the value of the DNX_FEED variable (https://www.nuget.org/api/v2/package/dnx-mono/stable).

dnx-mono.stable was not found in repository https://www.nuget.org/api/v2/package/dnx-mono/stable
This is most likely caused by the feed not having the version that you typed. Check that you typed the right version and try again. Other possible causes are the feed doesn't have a DNX of the right name format or some other error caused a 404 on the server.
