need to reconfigure the VM after vm deployment

[td_sk]

Hi All,

I am having a script to deploy a VM from an CSV file . I need to change the vm ( CPU & Memory)  configuration after vm deployment. where the name of the vm should be taken from csv.So any help is much appreciated.

Attaching the script used . ( downloaded and works fine)

$vms = Import-CSV D:\vm-deploy\vm-deploy.csv

foreach ($vm in $vms){

      $Template = Get-Template $vm.template

      $VMHost = Get-VMHost $vm.host

      $Datastore = Get-Datastore $vm.datastore

      $OSCustomization = Get-OSCustomizationSpec $vm.customization

      New-VM -Name $vm.name -OSCustomizationSpec $OSCustomization -Template $Template -VMHost $VMHost -Datastore $Datastore -RunAsync

}

## This cmd need to execute after the vm deployment completed. The VM name should come from the 1 colum of CSV file

Set-VM $vmname -NumCpu 2 -MemoryGB 5 -Confirm:$false

Write-Host "All vms deployed, " -ForegroundColor Green

Disconnect-VIServer -Confirm:$false

CSV file looks like this

Name,Template,host,datastore,customization

Test-VM,vm-dep-test,ESX02,P5-vm-stage,vm-deploy

Thanks in advance.....

Since you use the RunAsync switch and do customization of the VM, you will need to have a mechanism to wait till the VM is fully deployed and customised.

An excellent method for this is to use events, like Vitali described in his Waiting for OS customization to complete post.

In step 4 of Vitali's procedure you can do your changes to CPU and memory.

Hi,

  Thanks for this reply. I checked the link provided but it seems too big for me to understand as I am not a powershell expert. 

Can you please modify it in my script.

Thanks a lot for supporting this community.

A simpler, but not optimal, solution is to use the Wait-Task cmdlet.

Something like this

$vms = Import-CSV D:\vm-deploy\vm-deploy.csv

$tasks = @()

foreach ($vm in $vms){

      $Template = Get-Template $vm.template

      $VMHost = Get-VMHost $vm.host

      $Datastore = Get-Datastore $vm.datastore

      $OSCustomization = Get-OSCustomizationSpec $vm.customization

      $tasks += New-VM -Name $vm.name -OSCustomizationSpec $OSCustomization -Template $Template -VMHost $VMHost `

          -Datastore $Datastore -RunAsync

}

Wait-Task -Task $tasks

foreach($vm in $vms){

  Set-VM $vm.name -NumCpu 2 -MemoryGB 5 -Confirm:$false

}

The earlier approach work fine thanks for the update.

Can you please help us to modify the script .where the script need to execute  the second line if only the HDD2 value exists in CSV file. I tried different option but no luck.

The CSV file is created by an front end web tool and in back we are using ps script.So some times the user may not required the 2nd HDD in vm.

Sample CSV file

Name	Template	host	datastore	customization	CPU	Memory	hdd1	hdd2	hdd2
VM-Deploy	VMTMPENT2K8	ESXi-host1	VM-DEPLOY-DS	win 2008	4	12	5

Script we are using is

Connect-VIServer localhost

$vms = Import-CSV E:\lafarge-vm-dep\vm-deploy.csv

foreach($vm in $vms){

  Set-VM $vm.name -NumCpu $vm.CPU -MemoryGB $vm.Memory -Confirm:$false

  New-HardDisk -VM $vm.name -CapacityGB $vm.hdd1 -Datastore $vm.datastore -StorageFormat EagerZeroedThick -Controller "SCSI Controller 1"

  New-HardDisk -VM $vm.name -CapacityGB $vm.hdd2 -Datastore $vm.datastore -StorageFormat EagerZeroedThick -Controller "SCSI Controller 1"

New-HardDisk -VM $vm.name -CapacityGB $vm.hdd3 -Datastore $vm.datastore -StorageFormat EagerZeroedThick -Controller "SCSI Controller 1"

}
