Does XEN fully support KSM (Kernel Samepage Merging)? if yes then whats the=
 use of tmem?I understand the fact that KSM may provide overcommitment to t=
he Guest OSs but at the cost of CPU utilization for finding and merging sam=
e pages,but KSM can also be disabled.=0A =0AAnd why tmem supports only PV a=
nd not HVM ?If complete overcommitment is not good according to tmem concep=
t then why page sharing is allowed in HVM? Whether overcommitment is not pr=
ovided to HVM Guest?=0A=0A--Regards=0AAshwin Vasani=0APune Institute of Com=
