If you see error like this on Vagrant 1.2.2 and VirtualBox 4.2.14, when you do ‘vagrant up’
C:\Users\kazuki-h>vagrant up Bringing machine 'default' up with 'virtualbox' provider... [default] Importing base box 'hogehoge'... There was an error while executing `VBoxManage`, a CLI used by Vagrant for controlling VirtualBox. The command and stderr is shown below. Command: ["import", "C:/Users/kazuki-h/.vagrant.d/boxes/hogehoge/virtualbox/box.ovf"] Stderr: 0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100% Interpreting C:\Users\kazuki-h\.vagrant.d\boxes\hogehoge\virtualbox\box.ovf... OK. 0%... Progress object failure: RPC_S_SERVER_UNAVAILABLE 0x800706BA
Downgrade VirtualBox to 4.2.12, it will works fine.
It could raise again on Mac OS X or Linux, because VirtualBox’s changes might be directly responsible for this error.
Refarence:
Edit
This problem has been fixed in the version 4.2.16.
