Hello Keir,

Perhaps it was coincidence, but if i remember well, booting a 3.4.* hypervisor 
with the toolstack from a newer xen version (aka xen-unstable) seemed to work.
The thing is, default a xen build installs the different hypervisor versions 
beside each other, and you can use them as such in your grub config, the same 
with kernels.
But the toolstack (xend, xm, xentop etc.) gets overwritten. So after trying out 
a new hypervisor, you have to reinstall your old toolstack before booting in a 
older hypervisor.

So if it was no coincidence but desirable, at the moment xend and xentop from 
unstable don't seem to work on 3.4.2 hypervisor anymore.

Best regards,
 Sander                          mailto:linux@xxxxxxxxxxxxxx
