Project Remus 0.9 Released

From xen-devel:

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 guests.

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.
