In general, my experience is that xen in fedora is unstable. It usually works pretty well, but it has its rough edges, and this is hardly the first time a kernel update has broken xen. In the past, on the FC5 line, it's taken anywhere from a few days to a month or so for the fedora guys to fix an "unacceptable" problem.
That said, it's not like you're paying anybody money for Fedora.... I'm sure xen is much more stable in RHEL5.
BTW, you're aware you can have yum stop erasing old kernels, right?

And this is not something acceptable, so do you people want to to put kernel-xen in yum "exclude" ?
