Deploy VM from template and customization profile.

[sc_21111]

I’ve created a windows VM template and a customization profile which get VM name from deploy and  for static  IP during VM creation.

I’m trying to create a powercli script that reads Name and I’m from a CSV file and use them in a new-VM command line with Template and VM customization, however I’m not finding the correct way of doing this and get errors.

Can anyone spare some example of a script that would pass variables for Name and Static IP to the command line to create a VM with template and customization ?

Can you show us the code you are using and the errors you are getting?

Here the core of the script I'm trying to use

foreach ($v in $VMs) {
$vmhost = Get-VMHost -Server $vcenter0 -location EITESX | Get-Random -Count 1
$Datastore = Get-Datastore -Location DSCLUSTER_AL9000 | Get-Random -Count 1
$NicSpecsProperties = @{OSCustomizationNicMapping= Get-OSCustomizationNicMapping -OSCustomizationSpec $spec }
if ($IsDHCP){
$NicSpecsProperties.IpMode = “UseDHCP”}else{
#Assigning IP values
$NicSpecsProperties.IpMode = “UseStaticIP”
$NicSpecsProperties.IpAddress = $v.IP
$NicSpecsProperties.SubNetMask = $IPSubnetMask
$NicSpecsProperties.DefaultGateway = $IPGateway
$NicSpecsProperties.dns = $IPDNSServer1,$IPDNSServer2


}
Set-OSCustomizationNicMapping @NicSpecsProperties | Out-Null

New-VM -Name $v.NAME -Template $Template -OSCustomizationSpec $Spec -VMHost $vmhost -Datastore $Datastore
Start-VM -Name $v.NAME
}

Here is the error message

The VM gets created but without the customization

@LucD I just found that if I set only one DNS in the line 

$NicSpecsProperties.Dns = $IPDNSServer1

It works

So the issue is if I try to put two DNS with

$NicSpecsProperties.Dns = $IPDNSServer1, $IPDNSServer2

[LucD]

What is this supposed to do?

$NicSpecsProperties = @{OSCustomizationNicMapping= Get-OSCustomizationNicMapping -OSCustomizationSpec $spec }

And how can this even work?

if ($IsDHCP){

@LucD 

$NicSpecsProperties = @{OSCustomizationNicMapping= Get-OSCustomizationNicMapping -OSCustomizationSpec $spec }
if ($IsDHCP){
$NicSpecsProperties.IpMode = “UseDHCP”

}else{
#Assigning IP values
$NicSpecsProperties.IpMode = “UseStaticIP”
$NicSpecsProperties.IpAddress = $v.IP
$NicSpecsProperties.SubNetMask = $IPSubnetMask
$NicSpecsProperties.DefaultGateway = $IPGateway
$NicSpecsProperties.Dns = $IPDNSServer1,$IPDNSServer2

This part of code, taken by other examples, works by getting the Network parameters from the customization profile and then set the IP read from a CSV files.

I confirm that it's working fine now.

I set 02 DNS without issue. You should review again.

$SpecClone | Get-OSCustomizationNicMapping | set-OSCustomizationNicMapping -IpMode UseStaticIP -IpAddress $IP -SubnetMask $subnet -DefaultGateway $gateway -Dns $DNS1,$DNS2

[sc_21111]

@linhtm27 Yes I found what the problem was, it had an extra space in the dns2 variable

thanks
