There are some more files you can try deleting (lucky you!), in addition to
what Ian suggested:
/usr/lib/libxc* /usr/lib/libxutil* /usr/sbin/{xcs,xend,xentrace,xencons,xm}
Just for paranoia you could delete the contents of /var/xen (you might have to
recreate some directories later for Xend to work) and /etc/xen (assuming
you've nothing valuable in there).
Once you've deleted all those, and the original suggestions, make mrproper in
the Xen distribution (this deletes a whole load of stuff so watch out you
don't blow away any files you've added). Then make world to build from
scratch.
The guess I'm working with is that there's some sort of weird incompatibility
crept in between two changesets in unstable, which you may have been unlucky
enough to tickle. You may want to repull to get up to date, just in case it
got fixed later on...
If all this doesn't help, it's a bit mysterious. What are you using for a
console? xm create -c, xm console and xencons should all behave properly.
If you use telnet to connect to a domain console it sometimes gets confused.
