Not by design, but there is always the possibility that an errant DomU
could exploit a bug and compromise the hypervisor or Dom0 that way.
But depending on what your DomU does, it may be trusted by other servers
on your network so it's obviously never a good thing, but that's not
really anything to do with Xen.
In writing PV drivers for Windows I have caused complete system crashes
before, which means it is (or at least was) possible to crash the whole
system from a DomU. That was over a year ago and I never followed up
exactly what caused the problem other than to fix the bug in my driver.
I'd be interested to hear about what sort of analysis has been done on
this subject... do any papers exist?
