Re: [libvirt] [PATCH 2/6] Move all the QEMU migration code to a new file

The introduction of the v3 migration protocol, along with support for migration cookies, will significantly expand the size of the migration code. Move it all to a separate file to make it more manageable The functions are not moved 100%. The API entry points remain in the main QEMU driver, but once the public virDomainPtr is resolved to the internal virDomainObjPtr, all following code is moved. This will allow the new v3 API entry points to call into the same shared internal migration functions * src/qemu/qemu_domain.c, src/qemu/qemu_domain.h: Add qemuDomainFormatXML helper method * src/qemu/qemu_driver.c: Remove all migration code * src/qemu/qemu_migration.c, src/qemu/qemu_migration.h: Add all migration code. --- po/POTFILES.in | 1 + src/Makefile.am | 3 +- src/qemu/qemu_domain.c | 39 ++ src/qemu/qemu_domain.h | 4 + src/qemu/qemu_driver.c | 1297 ++------------------------------------------- src/qemu/qemu_migration.c | 1295 ++++++++++++++++++++++++++++++++++++++++++++ src/qemu/qemu_migration.h | 63 +++ 7 files changed, 1445 insertions(+), 1257 deletions(-) create mode 100644 src/qemu/qemu_migration.c create mode 100644 src/qemu/qemu_migration.h
