ESXi 5.5 unable to modify the RAM - System Resource Reservation

[mirceaflorin]

Hi,

  Can somebody try to see if they are able to change the RAM reservation from System resource allocation of an ESXi 5.5 ? Meaning setting it to 0, or to another value other than the one already specified there ?

Please let me know your results.

Thank you .

Additional notes. I tried also with a powerCLI script  :

$esx = Get-View -Id (Get-VMHost ESXi-FTH).Id

# The host/system object

$sysresinfo = $esx.SystemResources.Child[1]

# Not the children of host/system

$sysresinfo.Child = $null

# The new values for CPU

$sysresinfo.Config.cpuAllocation.reservation = 100

$sysresinfo.Config.cpuAllocation.Shares.Level = "Custom"

$sysresinfo.Config.cpuAllocation.Shares.Shares = 500

# The new values for MEM

$sysresinfo.Config.memoryAllocation.reservation = 512

$sysresinfo.Config.memoryAllocation.Shares.Level = "Custom"

$sysresinfo.Config.memoryAllocation.Shares.Shares = 500

# Commit the changes to specified host

$esx.UpdateSystemResources($sysresinfo)

Setting the CPU value works, but the Memory can't be changed . Anyone else tried it ? from vSphere client or something ?

Thanks.
