The messages you receive depends on the guest stack. That is the OS version
and driver type/version. Also you have to use QXL as card type.
Can you provide more details on Guest OS version and drivers installed?

All these are enabled without capabilities, that is they are assumed to
be supported by the server/client. The selection is done by spice-server
combining settings (like from Qemu) and bandwidth detection (for JPEG).
