[libvirt] [PATCH v2 00/73] qemu: Refactor migration parameters

This series changes the way we handle migration parameters and capabilities with several goals: - make it all consistent and avoid storing the same parameters in several structs - reduce the number of QMP commands we use for setting migration capabilities - concentrate the logic in a separate file and make the code for migration parameters and capabilities in qemu_migration.c less complicated - reset all parameters and capabilities at the end of migration - make adding new parameters and capabilities easier Version 2: - qemuDomainCheckMigrationCapabilities is moved to qemu_migration_params.c (rather than to qemu_migration.c) - supported migration capabilities are sent via migration cookie so that some caps may be automatically enabled only when both sides support them Jiri Denemark (73):
