Adjust host CPU / Memory reservations

[bowulf]

Is there a way to adjust a particular host's memory and CPU reservations for the Service Console? Thanks.

Hi,

Please refer the below thread for the same.

That thread seems to be about guests not the service console.

Afaiks there are 2 methods available to configure the reservations for the service console.

1) the ReconfigureServiceConsoleReservation method (corresponds with Configuration-Memory in the VI Client)

Apparantly one can only change the memory reservation that way.

$esxImpl = Get-VMHost -Name <ESX-hostname>
$esx = Get-View $esxImpl.ID
$esxmemMgr = Get-View $esx.ConfigManager.MemoryManager
 
$consolemem = <new-reservation-in-Mb> * 1MB
$esxmemMgr.ReconfigureServiceConsoleReservation($consoleMem)

Note that the new settings only becomes active after a reboot of the server.

2) the UpdateSystemResources method (corresponds with Configuration-System Resource Allocation-Advanced in the VI client).

This allows one to change CPU and memory reservations for the host/vim/console resource group.

Unfortunately I haven't been able (yet) to get this method to work.
