After installing VirtualBox 6.0.18 and then installing the Ubuntu VM, I rebooted the host and then run VirtualBox to start the guest OS again.
I got the following error message on the screen:
This is the message I got after acknowledging the dialog.
I searched on Google, reinstalled different versions of VirtualBox and installed/uninstalled with Admin and still like this. I don't have Hyper-V installed or enabled. I have WSL and its version 1.Failed to open a session for the virtual machine Ubuntu.
The virtual machine 'Ubuntu' has terminated unexpectedly during startup with exit code 1 (0x1). More details may be available in 'C:\Users\XXXX \VirtualBox VMs\Ubuntu\Logs\VBoxHardening.log'.
Result Code: E_FAIL (0x80004005)
Component: MachineWrap
Interface: IMachine {5047460a-265d-4538-b23e-ddba5fb84976}
I attach the ZIP version of the hardening log for diagnosis.
Thanks very much and Best Regards
