This new call is used in order to identify whether qemu, or
the management (e.g. libvirt), support seamless migration.
If it is supported, qemu spice cmd-line configuration should have
seamless-migration=on.
In addition, we disable seamless migration support if multiple clients
are allowed. Currently, only one client is supported.
