Ubuntu 18.04 guest boots up 1 in 5 times. In other times, a cursor in blank screen blinking with no progress

| Component: | guest additions/x11/graphics | Version: | VirtualBox 6.1.18 |
| Keywords: | blank screen hanging | Cc: | TeddyTeddy |
| Guest type: | Linux | Host type: | Windows |
Description
Host OS Info: Windows 10 Pro 64 bit, Version 1909 OS Build 18363.1316
Guest OS Info: Ubuntu 18.04 64 bit Attached is VM_Settings.PNG
Steps to reproduce:
- Start the guest
Expected outcome: (This happens 1 in every 5 trials) The guest boots up. The guest OS shows its desktop.
Observed outcome: (This happens 4 times in every 5 trials) A blank screen with a blinking cursor shows up. After a while, blinking stops, and the guest bootup process wont proceed. The blank screen will show indefinitely. If we see this happening, the only option is to kill the guest OS in Windows and then re-boot the host OS. During shotdown & reboot of the host os, the host OS may say "Referencing to an illegal memory in VMWare" or something like that.

Please try the latest testbuild from here. It should fix the hang you are encountering (SMP guest + VM with a serial port enabled in disconnected mode).
