Based on my personal experience
Wayland is not compatible with Oracle VirtualBox guest features such as copy/paste and display resizing.
One solution is to switch RHEL 10 to the X11 display system.
However, I encountered issues downloading or installing the X11 and GNOME packages on RHEL 10.
Alternative solution
If just want to copy paste terminal result, may use Pastebin.com or Connect External Storage To RHEL
