[BitVisor-devel-en:102] Re: Compiling for Virtualbox

[Dr. Lonnie Cumberland, PhD]

Hi All,

Just a quick update.  I had to enable EFI Booting in Virtualbox to get 
bitvisor to boot through, which it seems to do now and then goes back to 
the Grub menu so that I can choose my Ubuntu 22.04.

Then after I choose to boot the Ubuntu OS, then the screen just goes 
blank and nothing seems to happen.

Without bitvisor the Ubuntu OS boots up normally fine.

thoughts?

Thanks
Lonnie
