Subject: [PATCH 00/10] tools/xenstored: Bug fixes + Improve Live-Update
Date: Wed, 16 Jun 2021 15:43:14 +0100 [thread overview]
Message-ID: <20210616144324.31652-1-julien@xen.org> (raw)
From: Julien Grall <jgrall@amazon.com>
Hi all,
At the moment, Live-Update will, by default, not proceed if there are
in-flight transactions. It is possible force it by passing -F but this
will break any connection with in-flight transactions.
There are PV drivers out that may never terminate some transaction. On
host running such guest, we would need to use -F. Unfortunately, this
also risks to break well-behaving guests (and even dom0) because
Live-Update will happen as soon as the timeout is hit.
This series aims to allow to Live-Update more safely even when the option
-F is used.
The first part of the series contains a few fixes for bug found while
testing Live-Update.
Cheers,
Julien Grall (10):
