Re: [libvirt] [PATCH 06/16] Refactor tunnelled migration methods

To facilitate the introduction of the v3 migration protocol, the doTunnelMigrate method is refactored into two pieces. One piece is intended to mirror the flow of virDomainMigrateVersion2, while the other is the helper for setting up sockets and processing the data. Previously socket setup would be done before the 'prepare' step, so errors could be dealt with immediately, avoiding need to shut off the destination QEMU. In the new split, socket setup is done after the 'prepare' step. This is not a serious problem, since the control flow already requires calling 'finish' to tear down the destination QEMU upon several errors. * src/qemu/qemu_migration.c: --- src/qemu/qemu_migration.c | 159 ++++++++++++++++++++++----------------------- 1 files changed, 78 insertions(+), 81 deletions(-)
