GNOME Boxes lead developer Felipe Borges has been overhauling the application with a major rewrite and today announced the new beta release. GNOME Boxes has migrated to using the GTK4 toolkit and libadwaita. The new GNOME Boxes code can also handle installing Microsoft Windows 11 now without needing any manual workarounds for Secure Boot or TPM requirements.
The new GNOME Boxes code also introduces a VSOCK device for accessing VM contexts and other improvements. With the revamped GNOME Boxes, it’s also shifting to a Flatpak-first and only model for distributing of new GNOME Boxes releases.


You can use virt-manager over ssh, and you only need libvirt installed so probably already good if it’s a vm host. It works better for me than a full gui over vnc.
i tried that with x forwarding over ssh and it didn’t work all that well; what’s why i switched to vnc.
you can use ssh to forward the port and then use virt-manager locally to manage the remote server
