seamless migration: pre migration phase on the src side
sending SPICE_MSG_MAIN_MIGRATE_BEGIN_SEAMLESS and handling
SPICE_MSGC_MAIN_MIGRATE_CONNECTED_SEAMLESS
The src side signals the client to establish a connection
to the destination.
In seamless migration, the client is also used to perform
a sort of handshake with the destination, for verifying
if seamless migration can be supported.
see spice-protocol for more details:
