maxmem will default to initial allocation to the domain (128MB in this 
case). The 'mem=' parameter is parsed by the guest -- it does not 
inform Xen. To do that you would need to add 'maxmem=256' to your 
config file.
The lowmem/highmem balloon lines show how big the balloon is in terms 
of low memory (that is 1:1 mapped by the guest) and high memory (the 
area that needs to be kmapped by the kernel to access it). 'Hard limit' 
is the maximum reservation being enforced by Xen. In your case it is 
probed as 128MB, meaning that your 'xm maxmem' invocation had no 
effect. Sounds like it is broken. :-)
