Subject: [PATCH RFC 0/2] Add a design document for Live Updating Xen
Date: Thu,  6 May 2021 11:42:57 +0100	[thread overview]
Message-ID: <20210506104259.16928-1-julien@xen.org> (raw)

From: Julien Grall <jgrall@amazon.com>

Hi all,

A couple of years ago, AWS presented at Xen Summit [1] a new method called
"Live  Update" to replace the underlying the hypervisor without
rebooting/migrating VMs.

Since then we worked on implementing the feature in Xen and now have
a working PoC. This series is a split of David's series sent last year [1]
focusing on the design of the feature. We will start sending the code soon.

We will give an update and demonstrate the feature working during the
new Xen Summit.

More details on the feature can be found in the first patch #1 which
introduces the design document.

Best regards,
