There was an error while executing `VBoxManage`, a CLI used by Vagrant
for controlling VirtualBox. The command and stderr is shown below.Command: ["startvm", "d96e4abe-4361-47f8-a682-a1766d0b0f2a", "--type", "headless"]Stderr: VBoxManage.exe: error: Failed to get device handle and/or partition ID for 00000000017c43c0 (hPartitionDevice=0000000000000aa9, Last=0xc0000002/1) (VERR_NEM_VM_CREATE_FAILED)
