2017-06-01migration: Split qemu-file.hJuan Quintela
Split the file into public and internal interfaces. I have to rename the external one because we can't have two include files with the same name in the same directory. Build system gets confused. The only exported functions are the ones that handle basic types. Signed-off-by: Juan Quintela <quintela@redhat.com> Reviewed-by: Dr. David Alan Gilbert <dgilbert@redhat.com>

2015-10-20coroutine: move into libqemuutil.a libraryDaniel P. Berrange
The coroutine files are currently referenced by the block-obj-y variable. The coroutine functionality though is already used by more than just the block code. eg migration code uses coroutine yield. In the future the I/O channel code will also use the coroutine yield functionality. Since the coroutine code is nicely self-contained it can be easily built as part of the libqemuutil.a library, making it widely available. The headers are also moved into include/qemu, instead of the include/block directory, since they are now part of the util codebase, and the impl was never in the block/ directory either.

2015-02-05migration: Append JSON description of migration streamAlexander Graf
One of the annoyances of the current migration format is the fact that it's not self-describing. In fact, it's not properly describing at all. Some code randomly scattered throughout QEMU elaborates roughly how to read and write a stream of bytes. We discussed an idea during KVM Forum 2013 to add a JSON description of the migration protocol itself to the migration stream. This patch adds a section after the VM_END migration end marker that contains description data on what the device sections of the stream are composed of. This approach is backwards compatible with any QEMU version reading the stream, because QEMU just stops reading after the VM_END marker and ignores any data following it. With an additional external program this allows us to decipher the contents of any migration stream and hopefully make migration bugs easier to track down.

2014-10-14Tests: QEMUSizedBuffer/QEMUBufferDr. David Alan Gilbert
Modify some of tests/test-vmstate.c to use the in memory file based on QEMUSizedBuffer to provide basic testing of QEMUSizedBuffer and the associated memory backed QEMUFile type. Only some of the tests are changed so that the fd backed QEMUFile is still tested.

2014-05-14savevm: Remove all the unneeded version_minimum_id_old (rest)Juan Quintela
After previous Peter patch, they are redundant. This way we don't assign them except when needed. Once there, there were lots of case where the ".fields" indentation was wrong: .fields = (VMStateField []) { and .fields = (VMStateField []) { Change all the combinations to: .fields = (VMStateField[]){ The biggest problem (appart from aesthetics) was that checkpatch complained when we copy&pasted the code from one place to another.
