vagrant provider rackspace fails after vagrant-managed-servers plugin is installed

[stephencooke]

In the example below the managed-servers plugin is not compatible with other provisioning providers.

not sure if this is just vagrant not allowing you to specify the provider using --provider with a provision request.

My only workaround so far is to uninstall the managed-servers plugin everytime I need to provision to rackspace. Is there a better workaround available?

$ vagrant plugin install vagrant-managed-servers
Installing the 'vagrant-managed-servers' plugin. This can take a few minutes...
Installed the plugin 'vagrant-managed-servers (0.7.1)'!

$ vagrant plugin list
vagrant-cachier (1.2.1)
vagrant-host-shell (0.0.4)
vagrant-hosts (2.6.1)
vagrant-managed-servers (0.7.1)
vagrant-rackspace (0.1.10)
vagrant-share (1.1.4, system)
$ vagrant provision

No host IP was given to the Vagrant core NFS helper. This is
an internal error that should be reported as a bug

$ vagrant plugin uninstall vagrant-managed-servers
Uninstalling the 'vagrant-managed-servers' plugin...

$vagrant provision
==> pinas01: Rsyncing folder: /Users/PLACES/projects/platforms/rs_hosting/ => /vagrant

I have just tested this out using libvirt and dont see the same issues? is this a bug with vagrant-managed-servers or rackspace. plugin?
