Vagrant attempted to execute the capability 'change_host_name'
on the detect guest OS 'linux', but the guest doesn't
support that capability. This capability is required for your
configuration of Vagrant. Please either reconfigure Vagrant to
avoid this capability or fix the issue by creating the capability.

I guess that vagrant up can not load vagrant_plugin_guest_rancheros.rb in the box properly at the very first time.

[ailispaw]

To fix this, put the following into Vagrantfile.

module VagrantPlugins
  module GuestLinux
    class Plugin < Vagrant.plugin("2")
      guest_capability("linux", "change_host_name") do
        Cap::ChangeHostName
      end

      guest_capability("linux", "configure_networks") do
        Cap::ConfigureNetworks
      end
    end
  end
end
