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:
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
