There was an error while executing `VBoxManage`, a CLI used by Vagrant
for controlling VirtualBox. The command and stderr is shown below.

Command: ["modifyvm", "c8f076e7-b65f-4a48-9632-b65af0e27ba7", "--natpf1", "delet
e", "ssh"]

Stderr: VBoxManage.exe: error: The machine 'default' is
already locked for a session (or being unlocked)

omponent Machine, interface IMachine, callee IUnknown
VBoxManage.exe: error: Context: "LockMachine(a->session, LockType_Write)" at lin
