Vagrant global-status all VM's named default - vagrant

Question

When I run vagrant global-status, I get a listing back of all the vagrant managed VM's I'm running, but something I have not expected is output with the machine details. Even though I give every machine an explicit name during initialization, the value for name in the global-status output for every machine is always default.
Why does vagrant status or vagrant global-status not list the actual names of the boxes? At times, when I've destroyed a box, it has actually destroyed more than one box.

e44520d default virtualbox poweroff /Users/name/code/foo
1310726 default virtualbox poweroff /Users/name/code/bar
430fd52 default virtualbox poweroff /Users/name/code/baz
The machines are named foo, bar, baz... why are they showing as default?

Answer 1

If you have default Vagrantfile as configuration, your machine VM will be named default, so something like
Vagrant.configure(2) do |config|
config.vm.box = "ubuntu-12.04"
config.vm.hostname = "foo"
config.vm.network "forwarded_port", guest: 80, host: 8080
. . .
Now, if you have a multi machine configuration, you will have something like this in your Vagrantfile (simplified)
Vagrant.configure("2") do |config|
config.vm.box = "ubuntu-12.04"
config.vm.define "db" do |db|
db.vm.hostname = db.test
db.vm.provider "vmware_fusion" do |vm|
vm.vmx["memsize"] = "2048"
end
db.vm.provision "shell", path: "bootstrap-dev.sh"
end
config.vm.define "app", primary: true do |app|
app.vm.hostname = app.test
app.vm.network "private_network", "192.168.50.11"
app.vm.synced_folder "project/site", "/var/www"
end
end
In this case, you have defined 2 machines db and app and the vagrant global-status will prompt
id name provider state directory
