I have been running Arca OS 5.05 and Windows 10 without problems in VirtualBox. Got notified a new version of VB was available, so I said sure, let's upgrade. Afterwards both of my VMs fail to load with kernel errors. I uninstalled the update and reinstalled the previous version but I still get the same error.

For Arca OS:

Failed to open a session for the virtual machine Arca OS 5.05.

The virtual machine 'Arca OS 5.05' has terminated unexpectedly during startup with exit code 1 (0x1).

Result Code: NS_ERROR_FAILURE (0x80004005)
Component: MachineWrap
Interface: IMachine {85632c68-b5bb-4316-a900-5eb28d3413df}

For Windows 10:

Failed to open a session for the virtual machine Windows 10.

The virtual machine 'Windows 10' has terminated unexpectedly during startup with exit code 1 (0x1).

Result Code: NS_ERROR_FAILURE (0x80004005)
Component: MachineWrap
Interface: IMachine {85632c68-b5bb-4316-a900-5eb28d3413df}

They appear to be identical except for the machine name. Can anyone help me? Thanks.

Solved. Had to tell host to trust the extensions.

Glad you figured out what was wrong.

The errors you had were hardening errors. Could you please tell us how you did this:

And what the "extensions" were? Was this the Extension Pack?
