It is (partly) merged in unstable, thus by definition not ready yet for
production ;)

Using 32bit domains (both dom0 and domU) on a 64bit hypervisor works
quite ok at the moment.  Mixing 32 and 64bit pv domains on the same
machine needs patches for the tools which are not merged yet.  Also it
is broken right now.  And initially it also will be limited
feature-wise, the tools have to learn to handle domains with non-native
bitwidth ...

cheers,
  Gerd
