REMUS: Transparent high availability for Xen Official

[Sabre]

REMUS Site

Remus provides transparent, comprehensive high availability to ordinary virtual machines running on the Xen virtual machine monitor. It does this by maintaining a completely up-to-date copy of a running VM on a backup server, which automatically activates if the primary server fails. Key features:
The backup VM is an exact copy of the primary VM. When failure happens, it continues running on the backup host as if failure had never occurred.
The backup is completely up-to-date. Even active TCP sessions are maintained without interruption.
Protection is transparent. Existing guests can be protected without modifying them in any way.

REMUS is now officially part of Xen, which makes it a very attractive platform!

And a good choice, since VMware has VMotion and High Availability already.

Citrix is also pushing hard with their Xen line of products. Virt' is getting crowded with eager performers.

I'm curious to see how long the usual suspects will be able to undercut each other.
