This is something i would like to know too
As far as I know, copy paste with SPICE only works in graphical mode, with a X session running. Before X is starded, while in the console, no copy/paste is possible.
However, with virt-manager, it is possible to copy paste directly in the serial console of a vm installed with "--no-graphics"
This is a feature of virt-manager I deeply miss if it's not possible to make it work with VNC/SPICE remote consoles.
What would be great is the possibility to connect directly to the serial console of the vm from ovirt-manager (I think that's what virt-manager is doing seamlessly when no graphic hw is configured for the vm).
