I'm not sure what maxmem do, but I can say, this option does not allow 
to go beyond initial boot memory for pv_ops kernels and beyond 
static-max memory for -xen kernel.
I tested it with following python script (under xcp, with shutdowned 
squeezed to be sure not get 'reballanced'):
xc.domain_setmaxmem(domid,memory)
xs.write("","/local/domain/%i/memory/dynamic-min"%domid,str(memory*1024))
xs.write("","/local/domain/%i/memory/dynamic-max"%domid,str(memory*1024))
xs.write("","/local/domain/%i/memory/static-max"%domid,str(memory*1024))
xs.write("","/local/domain/%i/memory/target"%domid,str(memory*1024))

It works fine within noted ranges, but simply ignores any request higher 
them.
