It is definitely a problem with the XEN3PAE_DOMU kernel I built, though there is also an issue with trying to give it too much memory. Initially I tried the stock kernel with 'memory = 4000', but the domU failed to start. However after I changed this to 'maxmem = 2000' everything worked. Seems like the "PAE" part isn't quite doing its part :-)
I'd have thought 4000 would work, but I found that memory availabile in the domU was actually memory%4096, i.e. if you give it 4096 it won't boot as it ends up with zero RAM and 5120 gives you 1024MB.
Forgot to report that as a bug... -- Stephen
