Add ESXi to vCenter Automatically?

[Rhidian]

Hi,

Is it possible to add an ESXi host to an vCenter implementation automatically and change the VMs reservations memory allocation etc?

What I’m looking to achive is to have a base implemenatation that supports X users and by adding hosts expand the user base.

You can do it with PowerCLI

C:\PS>Add-VMHost 10.23.113.24 -Location Datacenter -User root -Password pass

To set CPU/memory reservations and limits you can modify this script. Currently I use it to disable limits

get-vm | %{Get-View $_.ID} | %{
  if(($_.Config.CpuAllocation.Limit -ne -1) -or ($_.Config.MemoryAllocation.Limit -ne -1)){
    Write "VM name: " $_.Name
    write " CPU limit: " $_.Config.CpuAllocation.Limit
    write " Memory limit: " $_.Config.MemoryAllocation.Limit

    $spec = new-object VMware.Vim.VirtualMachineConfigSpec;
    $spec.memoryAllocation = New-Object VMware.Vim.ResourceAllocationInfo;
    $spec.memoryAllocation.Shares = New-Object VMware.Vim.SharesInfo;
    $spec.memoryAllocation.Shares.Level = "normal";
    $spec.memoryAllocation.Limit = -1;
    $spec.CPUAllocation = New-Object VMware.Vim.ResourceAllocationInfo;
    $spec.CpuAllocation.Shares = New-Object VMware.Vim.SharesInfo;
    $spec.CpuAllocation.Shares.Level = "normal";
    $spec.CpuAllocation.Limit = -1;
    Get-View($_.ReconfigVM_Task($spec))
  }
}
