Dear Xen enthusiasts,
It's my pleasure to announce the release of Remus 0.9!
Remus provides comprehensive fault tolerance for Xen virtual
machines. If the physical machine hosting your VM fails, the backup
can take over instantly, as if you had migrated it to the backup at
the instant before the failure occured. There's no need for recovery,
because the backup is always completely up to date. Furthermore, Remus
runs completely transparently, requiring no changes to your existing
This release works with the tip of the xen-unstable repository, and
supports PV and HVM in 32-on-32, 64-on-64, 32-on-64, and 64-on-32
configurations. It has been tested using Linux (Ubuntu) PV guests, and
both Linux and Windows XP under HVM.
I believe that it is now ready for inclusion in Xen, and I would love
to have people try it out and let me know how it goes.
You can find more information, including installation and usage
instructions, at the web site:
The web site includes a list of improvements I have in mind over the
short term. Ideas (and patches) welcome!
