Hi Tony, The free memory the system has is 896M which is not multiple of 256M. From ldom 2.0, memory add/remove required to be 256M aligned. amount those 896M, only 768M can be assigned to domains. reset of 128M can be only used by primary domain through special cli ldm add-mem --unaligned primary.
So you should be able to do ldm add-mem 256M/512M/768M to any domains. Does this answer your question?
