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.

rom/device regions have a ram_addr that is composed of both an I/O handler (low bits) and RAM region (high bits); but qemu_ram_set_idstr() expects just a RAM region. Mask the I/O handler to make it happy. Tested-by: NStefan Weil <sw@weilnetz.de> Signed-off-by: NAvi Kivity <avi@redhat.com>

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>

Many places in QEMU call qemu_aio_flush() to complete all pending asynchronous I/O. Most of these places actually want to drain all block requests but there is no block layer API to do so. This patch introduces the bdrv_drain_all() API to wait for requests across all BlockDriverStates to complete. As a bonus we perform checks after qemu_aio_wait() to ensure that requests really have finished.

We add qemu_peek_buffer, that is identical to qemu_get_buffer, just that it don't update f->buf_index. We add a paramenter to qemu_peek_byte() to be able to peek more than one byte. Once this is done, to see if we have a subsection we look: - 1st byte is QEMU_VM_SUBSECTION - 2nd byte is a length, and is bigger than section name - 3rd element is a string that starts with section_name So, we shouldn't have false positives (yes, content could still get us wrong but probabilities are really low). v2: - Alex Williamsom found that we could get negative values on index. - Rework code to fix that part. - Rewrite qemu_get_buffer() using qemu_peek_buffer() v3: - return "done" on error case v4: - fix qemu_file_skip() off by one.

qemu_savevm_state() has some logic to stop the VM and to (or not to) resume it. But this seems to be a big noop, as qemu_savevm_state() is only called by do_savevm() when the VM is already stopped. So, let's drop qemu_savevm_state()'s stop VM logic.

Next commit will convert the query-status command to use the RunState type as generated by the QAPI. In order to "transparently" replace the current enum by the QAPI one, we have to make some changes to some enum values. As the changes are simple renames, I'll do them in one shot. The changes are: - Rename the prefix from RSTATE_ to RUN_STATE_ - RUN_STATE_SAVEVM to RUN_STATE_SAVE_VM - RUN_STATE_IN_MIGRATE to RUN_STATE_INMIGRATE - RUN_STATE_PANICKED to RUN_STATE_INTERNAL_ERROR - RUN_STATE_POST_MIGRATE to RUN_STATE_POSTMIGRATE - RUN_STATE_PRE_LAUNCH to RUN_STATE_PRELAUNCH - RUN_STATE_PRE_MIGRATE to RUN_STATE_PREMIGRATE - RUN_STATE_RESTORE to RUN_STATE_RESTORE_VM - RUN_STATE_PRE_MIGRATE to RUN_STATE_FINISH_MIGRATE Signed-off-by: NLuiz Capitulino <lcapitulino@redhat.com>

Today, when notifying a VM state change with vm_state_notify(), we pass a VMSTOP macro as the 'reason' argument. This is not ideal because the VMSTOP macros tell why qemu stopped and not exactly what the current VM state is. One example to demonstrate this problem is that vm_start() calls vm_state_notify() with reason=0, which turns out to be VMSTOP_USER. This commit fixes that by replacing the VMSTOP macros with a proper state type called RunState. Signed-off-by: NLuiz Capitulino <lcapitulino@redhat.com>

savevm and loadvm silently ignore block devices with removable media, such as floppies and SD cards. Rolling back a VM to a previous checkpoint will *not* roll back writes to block devices with removable media. Moreover, bdrv_is_removable() is a confused mess, and wrong in at least one case: it considers "-drive if=xen,media=cdrom -M xenpv" removable. It'll be cleaned up later in this series. Read-only block devices are also ignored, but that's okay. Fix by ignoring only read-only block devices and empty block devices.

In case we load the vmstate during incoming migration, we start from a clean, default machine state as we went through system reset before. But if we load from a snapshot, the machine can be in any state. That can cause troubles if loading an older image which does not carry all state information the executing QEMU requires. Hardly any device takes care of this scenario. However, fixing this is trivial. We just need to issue a system reset during loadvm as well.
