[Qemu-devel] [PATCH 0/8] Obtain dirty bitmap via VM logging

[Sanidhya Kashyap <sanidhya.iiith@gmail.com>]

Hi,

The following patches introduce the support of dirty bitmap logging and dumping
to a specified file. Still, some work is still left in the area of runstates that
I will try to work on after discussing this patch series.

v1 --> v2:
* Added two new run states to avoid simultaneous execution of both migration and
  bitmap dump process.
* Removed FILE pointer usage.
* Dumping the data only in machine-readable format.
* Tried to rectified mistakes of the previous version.



Sanidhya Kashyap (8):
  enable sharing of the function between migration and bitmap dump
  bitmap dump code via QAPI framework
  RunState: added two new flags for bitmap dump and migration process
  bitmap dump process with runstates
  hmp interface for dirty bitmap dump
  cancel mechanism for an already running dump bitmap process
  set the frequency of the dump bitmap process
  python script for extracting bitmap from a binary file
