This set of patches includes several fixes for replay and vmstate.
This patches add rrsnapshot option for icount. rrshapshot option creates
start snapshot at record and loads it at replay. It allows preserving
the state of disk images used by virtual machine. This vm state can also
use used to roll back the execution while replaying.
This set of patches includes fixes and additions for icount and
record/replay implementation:
- VM start/stop in replay mode
- overlay creation for blkreplay filter
- rrsnapshot option for record/replay
- vmstate fix for integratorcp ARM platform
- vmstate fixes for apic and rtc
v6 changes:
- Added overlay creation for blkreplay driver
- Fixed vmstate loading for apic and rtc
- Fixed instruction counting for apic instruction patching
v5 changes:
- Recording is stopped when initial snapshot cannot be created
- Minor changes
v4 changes:
- Overlay option is removed from blkreplay driver (as suggested by Paolo
Bonzini)
- Minor changes
v3 changes:
- Added rrsnapshot option for specifying the initial snapshot name (as
suggested by Paolo Bonzini)
- Minor changes

integratorcp: adding vmstate for save/restore
savevm: add public save_vmstate function
replay: save/load initial state
block: implement bdrv_snapshot_goto for blkreplay
