I don't have a lot of vagrant experience so sorry if this is a newbish issue. When I run vagrant up, with or without specifying '--provider=virtualbox', I still get an error saying the box is for vmware_fusion. I suspect to fix this I need a different download url.
c:\src\android-vm> vagrant up

a box for this provider, you should interrupt Vagrant now and add
the box yourself. Otherwise Vagrant will attempt to download the
full box prior to discovering this error.
