memory usage

[goodface]

i have one esxi host in cluster. Esxi host has 65 gb memory . memory usage is 59 gb  but virtual machine not usage this memory also i checked the on vrealize . vm's doest use 59 gb memory on vrealize max memory demand report . vcenter alarm always send host memory alarm . Also why i see memory usage 59gb on vcenter ? i dont want to take alarms and dont want to see high memory usage on vcenter when vm's using low memory

Why vm's usage memory and host memory usage are different on screen ?

vcenter 5.5 u2 / esxi 5.5 u2

host : 65 gb memory

vm's memory totaly : 82 gb
