Whonix ™ in VirtualBox - Troubleshooting - Whonix ™ does not Start?

From Whonix

< VirtualBox


If the "Failed to load unit 'PATM' (VERR_SSM_FIELD_NOT_CONSECUTIVE)." error appears, VT-x must be enabled in BIOS settings, see instructions.

VT-x is disabled in BIOS[edit]

If the following error message appears.

Failed to open a session for the virtual machine {{gateway_product_name}}.

VT-x is disabled in the BIOS.


AMD-V is disabled in the BIOS (or by the host OS).

Then enable VT-x in BIOS settings.

Enable VT-x in BIOS[edit]

Go to your BIOS settings. For basic instructions, see: [archive]

Then enable VT-x. This is sometimes also called AMD-V, virtualization, SVM or MIT perhaps under Advanced Core settings.

Error In supR3HardenedWinReSpawn[edit]

VirtualBox supR3HardenedWinReSpawn.png
Do not update whilst the VMs are running, otherwise VirtualBox must be reinstalled.


If this error appears, sometimes it helps to:

  1. Try and convert the vmdk to vdi.
  2. Remove the old vmdk from the VM.
  3. Attach the new vdi.


debian kernel: VMMR0InitVM: Revision mismatch, r3=132055 r0=130347

Happening when upgrading VirtualBox on host while still having existing VMs running. Solution: shut down all VMs and restart VMs.

Import Whonix ™ Images[edit]

Using the VirtualBox GUI to import Whonix ™ images should work well in most cases. If not, follow the steps below.

1. Check if there is enough free disk space.

2. Refer to the Whonix ™ Install Screenshots and/or Video Tutorials.

3. Delete any half-imported or otherwise broken virtual machine images.

4. Use the VBoxManage command line tool and copy the output.

VBoxManage unregistervm "Whonix-Gateway" --delete

VBoxManage unregistervm "Whonix-Workstation" --delete

5. Navigate to the folder where Whonix ™ was downloaded and import Whonix-Gateway ™ and Whonix-Workstation ™ by using the VBoxManage command line tool.

VBoxManage import Whonix-Gateway.ova

VBoxManage import Whonix-Workstation.ova

6. Clean (anonymize) the output.

Remove operating system user name or any problematic paths.

7. Contact lead Whonix ™ developer Patrick Schleizer and send the output.

VirtualBox Screen Resolution Bug[edit]


If the display presents like the image on the right-hand side, then you are affected by a screen resolution bug which only occurs in VirtualBox. To correct the resolution, apply the following workaround.

  1. Power off the VM.
  2. Restart the VM.
  3. Maximize the VM window after start of the VM as soon as possible.
  4. VirtualBox VM WindowViewVirtual Screen 1Choose any, resize to another resolution
  5. VirtualBox VM WindowViewAuto-resize Guest Display
