The Remus project at the University of British Columbia uses high-rate checkpointing, and thus SMP guests aren't a problem. There's a paper on this apperaing at NSDI. Peter Chen's group at the University of Michigan has done a lot of work on using determinisitic replay for Fault Tolerance. George Dunlap's paper at VEE shows this can be extended to SMP guests for some applications: http://www.eecs.umich.edu/~pmchen/papers/dunlap08.pdf1 There's also Daniel Stodden's ongoing work presented at XenSumit #4. http://xen.org/files/xensummit_4/20060417-stodden-newyork-xensummit.pdf There's also a commercial Fault Tolerant product already on the market for Xen, Marthon's EverRun FT that works on top of Citrix XenServer.

As for the Slides, they are located at http://xen.org/files/fosdem-feb2008-s.pdf. I have also not seen the video show up yet on the FOSDEM website but will add that link. Thanks for the questions.

I can find research papers regarding this and a product by a commercial company that appears to use this technology but nothing about it on the Xen site. The video from the presentation is not online (yet) and I can't find the slides. Does/Will Xen (in its open source guise) support this?
