From mboxrd@z Thu Jan 1 00:00:00 1970 From: Eric Shelton Subject: qemu-upstream stubdom - status? Date: Mon, 7 Apr 2014 16:50:16 -0400 Message-ID: Mime-Version: 1.0 Content-Type: multipart/mixed; boundary="===============7071813287392629313==" Return-path: List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Sender: xen-devel-bounces@lists.xen.org Errors-To: xen-devel-bounces@lists.xen.org To: "xen-devel@lists.xen.org" , Anthony PERARD , Ian Jackson List-Id: xen-devel@lists.xenproject.org --===============7071813287392629313== Content-Type: multipart/alternative; boundary=001a11c214ecfca83504f67a046b --001a11c214ecfca83504f67a046b Content-Type: text/plain; charset=ISO-8859-1 Where does this feature stand currently? It pops up under a couple of names and proposed implementations (e.g., "qemu-xen stubdomains", "qemu-upstream stubdom, Linux", and "qemu-upstream stubdom, BSD libc"), so it seems likely I missed something. If I understand this email from Sept 2013 ( http://lists.xen.org/archives/html/xen-devel/2013-09/msg02881.html), qemu-xen stubdomains might have made it into 4.4 if the schedule had been slipped a little, suggesting some active effort. On the other hand, the same email designated the efforts attached to Anthony and Ian as "prognosis: ?". Anthony released a patchset/branch about a year ago, but that got sidelined in favor of getting Xen on ARM. However, I did not identify any more recent patches. It remains appealing to make use of the more recent developments in qemu-upstream, but with the isolation provided by a stubdomain. The many improvements made in teasing driver domains out of dom0 strengthen this appeal (for example, using OpenSolaris as a ZFS-based storage domain). What are the most recent patches or repository for this feature? Thanks, Eric --001a11c214ecfca83504f67a046b Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable
