docs: create config/, devel/ and spin/ subdirectories

2017-06-07T16:22:03+00:00

Developer documentation should be its own manual. As a start, move all developer-oriented files to a separate directory. Also move non-text files to their own directories: docs/config/ for QEMU -readconfig input, and docs/spin/ for formal models to be used with the SPIN model checker. Reviewed-by: Daniel P.

migration: convert post-copy to use QIOChannelBuffer

2016-05-26T06:01:34+00:00

The post-copy code does some I/O to/from an intermediate in-memory buffer rather than direct to the underlying I/O channel. Switch this code to use QIOChannelBuffer instead of QEMUSizedBuffer.

postcopy: Remove the x-

2016-03-11T12:23:59+00:00

Postcopy seems to have survived a cycle with only a few fixes, and Jiri has the current libvirt wired up and working ( https://www.redhat.com/archives/libvir-list/2016-March/msg00080.html ) so remove the experimental tag.

migration: Use normal VMStateDescriptions for Subsections

2015-06-12T04:53:57+00:00

We create optional sections with this patch. But we already have optional subsections. Instead of having two mechanism that do the same, we can just generalize it. For subsections we just change: - Add a needed function to VMStateDescription - Remove VMStateSubsection (after removal of the needed function it is just a VMStateDescription) - Adjust the whole tree, moving the needed function to the corresponding VMStateDescription Signed-off-by: Juan Quintela

savevm: Remove all the unneeded version_minimum_id_old (rest)

2014-05-14T13:24:51+00:00

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.

savevm: Ignore minimum_version_id_old if there is no load_state_old

2014-05-05T20:15:03+00:00

At the moment we require vmstate definitions to set minimum_version_id_old to the same value as minimum_version_id if they do not provide a load_state_old handler. Since the load_state_old functionality is required only for a handful of devices that need to retain migration compatibility with a pre-vmstate implementation, this means the bulk of devices have pointless boilerplate. Relax the definition so that minimum_version_id_old is ignored if there is no load_state_old handler. Note that under the old scheme we would segfault if the vmstate specified a minimum_version_id_old that was less than minimum_version_id but did not provide a load_state_old function, and the incoming state specified a version number between minimum_version_id_old and minimum_version_id. Under the new scheme this will just result in our failing the migration. Signed-off-by: Peter Maydell Reviewed-by: Michael S. Tsirkin Signed-off-by: Michael S. Tsirkin Signed-off-by: Juan Quintela
