virtualbox.org

Hi,

I am on a new HP Prodesk with windows 10 Pro 1909.
I want to run Ubuntu server 18.04 on VirtualBox.
Firstly, I got a blank screen in VirtualBox after "Start" the image. It supposed to have bootup information when booting from the live CD, but there is nothing.
Then I disabled VT in BIOS. VirstualBox complained about it as expected.
And then I reverted BIOS changes and started VirtualBox again. This time, to my surprise, I got a new hardening issue.

I spent a whole day on this without any progress. Hope you could show me some clue.

Thanks!
Simon

The transition from "no VT-x" to "VT-x enabled" causes Windows to turn on a bunch of features that require virtualization - features that were previously suppressed because Windows saw you were already using a third party hypervisor.

See last post in FAQ: I have a 64bit host, but can't install 64bit guests.

You also seem to have something called "Panda Security" installed. That needs to go bye-bye. Your PC needs to be a snake-oil-free zone.
