Ubuntu 20.04.1 install crash on Windows 10 host.

Post by karlkras »

Host: Microsoft Windows [Version 10.0.18363.900]
VirtualBox: Version 6.1.12 r139181 (Qt5.6.2)
Iso install:
ubuntu-20.04.1-desktop-amd64.iso

This crashes during installation. Not much else to say. Any ideas/reports why?
Please, I'm disturbed.

It is possible Hyper-V is enabled.

Start the guest from full normal shutdown, not save-state. Run until you see the problem happen, then shut down the guest from within the guest OS if possible. If not possible, close the Virtualbox window for the guest with the Power Off option set.

Right-click the guest in the main Virtualbox window's guest list, choose Show Log. Save the far left tab's log. Search the log for these words:

Attempting fall back to NEM

If these words are in your guest's vbox.log, Hyper-V is enabled. See HMR3Init: Attempting fall back to NEM (Hyper-V is active)

If these words are not present, zip the vbox.log, and post the zip file, using the forum's Upload Attachment tab.
