Question

I just got laravel homestead to run yesterday using powershell. Now, it won't even run. I just suspended vagrant and turned off my pc. Now it's just giving me this error:

Bringing machine 'default' up with 'virtualbox' provider...
==> default: Checking if box 'laravel/homestead' is up to date...
==> default: Clearing any previously set forwarded ports...
There was an error while executing `VBoxManage`, a CLI used by Vagrant
for controlling VirtualBox. The command and stderr is shown below.

Command: ["modifyvm", "b21f2dd0-7f73-4d0f-b1e0-0f82ecdda1fe",

"--natpf1", "delete", "tcp44300", "--natpf1", "delete", "tcp54320", 
"--natpf1", "delete", "tcp8000"]

Answer 1

I had the same problem and the previous answer didn't work for me. I opened the VirtualBox GUI and saw that the virtual machine was running. I stopped it and then I executed "vagrant up". All worked well.

Answer 2

Ok, so I finally fixed the problem. Tried restarting my laptop and it's not giving me that error anymore. Here's what I did:

1. Right click on "This PC" / "My Computer" on windows desktop
2. Select "Properties"
3. Go to "Advanced" tab
4. Click "Environment Variables..." at the bottom
5. Under System Variables click "New..."
6. Set "Variable name" to "VBOX_INSTALL_PATH"
7. Set "Variable value" to "C:\Program Files\Oracle\VirtualBox\"
8. Select "OK" and close all the other settings windows

It should work fine.

Answer 6

Disable Hyper-V virtualization that is enabled in Windows.

Open a command prompt as administrator and run the following command:

dism.exe /Online /Disable-Feature:Microsoft-Hyper-V

Afterwards, reboot the PC and try VirtualBox again.
