The failure comes from the X11 clipboard backend (shclx11) when VBoxClient --clipboard -f -vvv runs under XWayland and fails to dlopen libXt.so.6. Start with the clipboard service code that selects the X11 backend and the dlopen call that logs the error, and check how the RHEL guest-additions package declares its X11 dependencies. Done means either a clean fallback or an actionable error when libXt/libXmu are missing, confirmed by the reproduction steps on a RHEL 10 GNOME guest.

Component
Guest Additions/Shared Clipboard
What happened?
Shared clipboard does not work in a RHEL 10 guest with a default GNOME (Wayland) desktop, although Guest Additions install successfully and Shared Clipboard is set to Bidirectional.
VBoxClient --clipboard -f -vvv fails with:
shclx11 rtldrNativeLoad: dlopen('libXt.so.6', RTLD_NOW | RTLD_LOCAL) failed: libXt.so.6: cannot open shared object file: No such file or directory
How can we reproduce this?
- Install RHEL 10.x with the default "Server with GUI" or "Workstation" environment (GNOME, Wayland only).
- Install Guest Additions
7.2.20(with kernel-devel, gcc, make, perl etc. so the modules build). - Set Devices → Shared Clipboard → Bidirectional, then reboot and log in to GNOME.
- Confirm
rpm -q libXt libXmureports both as not installed. - Copy text on the Windows host and try to paste in the guest (and the reverse): nothing is transferred.
- Run
VBoxClient --clipboard -f -vvv: session type is detected as XWayland, the X11 backend is chosen and fails to dlopen libXt.so.6.
