  Hi,

I think we should simply use a global variable for 'running' here.  It's
global state anyway.  Having this in per-display state struct buys us
nothing and adds alot of code for updating and display list maintainance.

If you don't register qemu_spice_vm_change_state_handler on new
spice-server you should #ifdef the whole function, not the body only.

cheers,
