Virtual Machine can not start

Description

Hi,

After Virtual Box upgrade to 6.1.6 r137129 (Qt5.6.2) many machines stop to work. Virtual BOX and Guest Aditional upgrade were performed fine. But after few days, in some VMachine the screen stay black after the power on. The issue happened in some WINDOWS10 and FEDORA Virtual Machine, but not on all.

I tried to uninstall and install VIRTUAL BOX but the black screen issue is still present. The only solution is delete and create the Machine from scratch.

Could some one help me to debug the issue to understand why it is happen?

@Ivan_70:

I am seeing something similar (black screen after login) with all of my RHEL7x VMs running under Win10, for which GAs have been updated with 6.1.x.

With some experimentation, I've found the following work-around: if you toggle full-screen mode (by hitting the host-F key twice) anytime after the VM is initiated, even as soon as the VirtualBox 6.1 splash screen is displayed, you'll get a fully correct display after login (verified most recently to work with both GA 6.1.10 & GA 6.1.12) !!

Don't know if this will help in your particular case, but I thought I'd post it here just in case.
