The error you should see for virsh migrate --tunnelled is "cannot perform tunnelled migration without using peer2peer flag". Virsh should not try to guess that tunnelled implies peer2peer because there's a possibility someone implements tunnelled migration that transfers data through the client which controls migration and thus p2p flag would not be required and virDomainMigrateToURI3 would be a wrong API. Not that the APIs are designed for that but if I correctly remember discussions we had about this topic in the past, the goal was virsh should not be enforcing (or even automatically adding) p2p flag for tunnelled migrations for better compatibility with future. > Signed-off-by: Richard W.M.
