If the guest has reached "maxmem" configured via the configuration file, 
you should restart your guest to allocate more memory. What you can do 
is configure "maxmem" to the maximum available memory and adjust the 
current memory when you need it using  "virsh setmem <domain> <memory in 
KB>"

 <memory>1048576</memory>
  <currentMemory>512000</currentMemory>

Here memory is the maxmemory and currentMemory is what the guest has 
been allocated currently.
