Hi all,
this is the seventh version of the Xen save/restore patch series.
We have been discussing this issue for quite a while on #qemu and
qemu-devel:
http://marc.info/?l=qemu-devel&m=132346828427314&w=2
http://marc.info/?l=qemu-devel&m=132377734605464&w=2
Please review the second patch: Introduce "save_devices".
Changes in v7:
- rename save_devices to save-devices-state.
Changes in v6:
- remove the is_ram parameter from register_savevm_live and sets is_ram
if the device is a live_savevm device;
- introduce save_devices as a QAPI command, write a better description
for it;
- fix CODING_STYLE;
- introduce a new doc to explain the save format used by save_devices.
Changes in v5:
- rebased on b4bd0b168e9f4898b98308f4a8a089f647a86d16.
Changes in v4:
- following Anthony's suggestion I have introduced a new monitor command
to save the non-ram device state to file;
- I have also removed the hack not to reset the cirrus videoram on
restore, because it turns out that the videoram doesn't need to be
reset in the reset handler at all (tested on Win2K, where the problem
was found in the first place).
This is the list of patches with a diffstat:
Anthony PERARD (2):
xen mapcache: check if memory region has moved.
xen: do not allocate RAM during INMIGRATE runstate
Stefano Stabellini (4):
cirrus_vga: do not reset videoram
Introduce "save-devices-state"
Set runstate to INMIGRATE earlier
xen: record physmap changes to xenstore
