Just thought I'd pass along that I have successfully installed FreeBSD 6.3 into a Xen 3.1 HVM. Went a lot smoother than I expected. Haven't done any benchmarking or stress testing or port installs or anything. But so far it's working nicely. Here's all the info. If you'd like to see anything else, let me know.
