Description
In case of contention existing vms memory should automatically get reduced (should be between reserved and max) so that new vms can accommodate on host.But i did not see this behavior on vmware.
Guest OS always shows max memory even in case of contention .
Steps to reproduce
---------------------------
1-Preapre a CS setup with vmware esxi5.1
1-Set memory overcommit to 2
3-Create a service offering of1 (cpu=500MGZ,Memory=4096MB)
4-Deploy vms using service offering of1 till no memory left on hypervisor
5-run cat /proc/meminfo on each guest
Actual
----------
1-Step 5 shows each guest is having 4096MB
2-Total guest os memory(at guest OS level) >what physically available on host
Expected
--------------
1-VMs memory should dynamically get adjusted (<4096) in order to accommodate new vms on host
2-Total guest os memory (at guest OS level) <=what physically available on host
