PCAP=1 ./run migrate/bidirectional gives an overview of how the whole thing is working. Add 12 tests in total, checking basic functionality with and without flows in both directions, with and without sockets in half-closed states (both inbound and outbound), migration behaviour under traffic flood, under traffic flood with > 253 flows, and strict checking of sequences under flood with ramp patterns in both directions. These tests need preparation and teardown for each case, as we need to restore the source guest in its own context and pane before we can test again. Eventually, we could consider alternating source and target so that we don't need to restart from scratch every time, but that's beyond the scope of this initial test implementation. Trick: './run migrate/*' runs all the tests with preparation and teardown steps.
