From 39b65c2e315ad5565e22b98ea2a4498ec2edfad2 Mon Sep 17 00:00:00 2001 From: aliguori Date: Mon, 13 Oct 2008 03:10:22 +0000 Subject: Introduce a buffered file wrapper for QEMUFile This patch introduces a buffered QEMUFile wrapper. This allows QEMUFile's to be rate limited. It also makes it easier to implement a QEMUFile that is asynchronous since the current QEMUFile API requires that all reads and writes be synchronous. The only real non-obvious part of the API is the "frozen" concept. If the backend returns EAGAIN, the QEMUFile is said to be "frozen". This means no additional output will be sent to the backend until the file is unfrozen. qemu_file_put_notify can be used to unfreeze a frozen file. A synchronous interface is also provided to wait for an unfreeze event. This is used during the final part of live migration when the VM is no longer running.
