Still on 3.0.3 at the moment - about to switch to 3.0.4 though. HOWEVER,
searching both the 3.0.4 and unstable sources, I don't see the specific
fix I am proposing in tools/libxc; can you tell me exactly what/where
your patch was?

Thanks,
Simon

PS: To answer Ian's point -- I agree that PV save/restore of guests >
2GB works; I have no idea at the moment why save/restore works and dump
does not but I can tell you that building with _FILE_OFFSET_BITS=64
makes the dump work... I'm just concerned that there might be some other
dependency that this breaks...
