Is it PV domU? If yes, you can try putting a setting like this on domU config

memory = "4000"
maxmem = "8000"

in that example, domU will start with 4000M memory, but you'll be able
to increase it later with "xm mem-set" up to 8000MB. Note that there
are some memory overhead necessary to be able to balloon-up, so you
should set a realistic value for maxmem.
