Subject: [Qemu-devel] [PATCH v2 0/3] Event notifications for balloon driver
Date: Mon, 21 May 2012 17:59:50 +0100	[thread overview]
Message-ID: <1337619593-25823-1-git-send-email-berrange@redhat.com> (raw)

This series is a followup to 2 previously posted patches

 * BALLOON_CHANGE QMP event:
   http://lists.nongnu.org/archive/html/qemu-devel/2012-05/msg02215.html

 * query-events QMP command: 
   http://lists.nongnu.org/archive/html/qemu-devel/2012-05/msg02255.html

Changes since v1:

 - Use a static array of strings for QMP event ID -> string conversion
 - Add BALLOON_CHANGE to qmp-events.txt

There is also a new patch in this series, which introduces the ability
todo simple rate limiting of stateless monitor events. With the ballooning
of a 1.8 GB guest, down to 0.9 GB this reduced the number of events
emitted from ~50 down to just 4, spread across a 4 second time window.
It is important to note that events are only discarded when they are
obsoleted by a newer event. So an application is guarenteed to see the
final balloon event, with at worst a 1 second delay.

This series is being tested with a corresponding patch to libvirt
for handling balloon events
