Hi,
I am using Licensed Vsphere 5.1 (Upgraded from Vsphere 4)
I am facing a problem after upgrade, Virtual machines are not sharing RAM
Like if i have two machine with 2 GB RAM then total RAM Usage on HOST becomes 4 GB but actually active memory usage is about 1 GB only.
This was not a problem in Vsphere 4 it shows active memory as HOST memory usage but in Vsphere 5 Virtual machine are not sharing RAM and reserve full RAM when powered on.
Maybe there is some setting to enable memory sharing or to turn off this full reservation of RAM.
