From a7ae8355b4465bb52021451a77615f83872970b0 Mon Sep 17 00:00:00 2001 From: Stefano Stabellini Date: Wed, 25 Jan 2012 12:24:51 +0000 Subject: Introduce "xen-save-devices-state" - add an "is_ram" flag to SaveStateEntry; - register_savevm_live sets is_ram for live_savevm devices; - introduce a "xen-save-devices-state" QAPI command that can be used to save the state of all devices, but not the RAM or the block devices of the VM. Changes in v8: - rename save-devices-state to xen-save-devices-state. 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.
