This is a problem with Ubuntu and not VirtualBox. I spend a few hours today fighting with 24.04.02 in libvirt only to realize that they are using some fancy new GUI library for the installer which crashes on all VMs: https://www.dell.com/support/kbdoc/en-us/000123893/manual-no...

Mandatory Ubuntu considered harmful.

If only NVidia considered Debian a first class distribution so I never had to use Ubuntu again.
