Convert VirtualBox .vdi image to .raw then to KVM .qcow2

I installed Windows 10 into VirtualBox to replace my old 32 bit Windows 7 which can no longer accommodate modern Visual Studio. However the Visual Studio Installer just hard locks my VirtualBox image. So I installed KVM and converted the image and it works fine.

I got the instructions for converting the image from https://www.tecmint.com/migrate-virtualbox-vms-into-kvm-vms/

Very simple straightforward instructions for converting from VirtualBox .vdi to KVM .qcow2 image.

You have to first convert the .vdi to a raw image, then convert the raw image to a .qcow image

$ vboxmanage clonehd --format RAW /home/james/VirtualBox\ VMs/debian/debian.vdi debian_10_Server.img

$ qemu-img convert -f raw debian_10_Server.img -O qcow2 debian_10_Server.qcow2

Restore missing "Share Entire Screen" functionality in Zoom under Gnome

Hey, I know its been a long time since I rapped at ya.

(That was a reference to Jim Anchower from The Onion)

Anyway, Zoom does not work right on Ubuntu (I'm back on Ubuntu) in that sharing the screen is not an option. This is apparently a bug with Wayland and you could do a horrible fix of moving off of Wayland and back to Xorg, but screw that.

You can make it work, though this should probably be a temporary fix that you turn on and off when you are done sharing.

The short version of the workaround is: do alt-F2, type "lg" and hit return; then enter

  global.context.unsafe_mode = true

and hit return; then escape to go back to things. You might want to reverse this (change "true" to "false") afterwards.
