问题:

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", "ssh", "--natpf1", "delete", "tcp33060", 
"--natpf1", "delete", "tcp44300", "--natpf1", "delete", "tcp54320", 
"--natpf1", "delete", "tcp8000"]

Stderr: VBoxManage.exe: error: Code E_FAIL (0x80004005) - Unspecified   
error (extended info not available)
VBoxManage.exe: error: Context: "LockMachine(a->session,  
LockType_Write)" at line 493 of file VBoxManageModifyVM.cpp

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.

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

For Mac OS, close all the running VMs and restart the virtual box using following command:

sudo "/Library/Application Support/VirtualBox/LaunchDaemons/VirtualBoxStartup.sh" restart

Try to follow these steps 1. Run cmd as Administrator 2. vagrant halt 3. vagrant up 4. if required vagrant provision but once vagrant is up.

回答5:

1. First of all destroy the virtual box with vagrant destroy.
2. Navigate to C:\Users\Justice replace justice by username.
3. Delete the .vagrant.d folder.
4. Go into VirtualBox VMs folder and delete everything inside it.
5. Start it again with vagrant up.

It should work fine.

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.
