OK.


You can easily test it with Remus. With xl, memory replication functionality is already
in place. so xl remus command should work.

Should "xl remus $domain localhost" work?  How would one test the fail-over mechanism?  Are there any other requirements for the guest, the kernel, &c?

I just ran the above command on xen-unstable, and after 10 minutes or so the guest crashed with some kind of a kernel double-fault.

Are we running any remus stuff in our testing infrastructure?
