[Qemu-devel] [PATCH 05/22] savevm: load_vmstate(): Return 'ret' on error

[Luiz Capitulino]

When looping to restore the snapshot on all drives, load_vmstate()
will return 0 if bdrv_snapshot_goto() returns an error.

This seems a trick to avoid the call to vm_start() in do_loadvm(),
however it brings two problems:

1. The call to load_vmstate() from main() will succeed

2. In QMP, it's just not allowed to fail and return 0

This commit fixes that.
