> 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
