Now that qemu_fseek does not exist anymore, there is no reason to do an fseek before fread/fwrite when operating on an stdio file. Thus, unify the get/put_buffer callbacks used by qemu_fopen with those used for pipes. Reviewed-by: NOrit Wasserman <owasserm@redhat.com> Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com>

- 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.

The migrate command is one of those commands where HMP and QMP completely mix up together. This made the conversion to the QAPI (which separates the command into QMP and HMP parts) a bit difficult. The first important change to be noticed is that this commit completes the removal of the Monitor object from migration code, started by the previous commit. Another important and tricky change is about supporting the non-detached mode. That is, if the user doesn't pass '-d' the migrate command will lock the monitor and will only release it when migration is finished. To support this in the new HMP command (hmp_migrate()), it is necessary to create a timer which runs every second and checks if the migration is still active. If it is, the timer callback will re-schedule itself to run one second in the future. If the migration has already finished, the monitor lock is released and the user can use it normally. All these changes should be transparent to the user. Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com> Signed-off-by: NLuiz Capitulino <lcapitulino@redhat.com>

The Monitor object is passed back and forth within the migration/savevm code so that it can print errors and progress to the user. However, that approach assumes a HMP monitor, being completely invalid in QMP. This commit drops almost every single usage of the Monitor object, all monitor_printf() calls have been converted into DPRINTF() ones. There are a few remaining Monitor objects, those are going to be dropped by the next commit.

Currently creating a memory region automatically registers it for live migration. This differs from other state (which is enumerated in a VMStateDescription structure) and ties the live migration code into the memory core. Decouple the two by introducing a separate API, vmstate_register_ram(), for registering a RAM block for migration. Currently the same implementation is reused, but later it can be moved into a separate list, and registrations can be moved to VMStateDescription blocks. Signed-off-by: NAvi Kivity <avi@redhat.com>
