Configure Customization Specifications in vSphere

Create customization specifications, one for Linux and one for Windows, for use by the virtual machines images you deploy. Customization specifications are XML files that contain system configuration settings for the guest operating systems used in the virtual machines. You can use the customization specifications when you create cloud templates in vRealize Automation.

Procedure

  1. Create a Customization Specification for Linux Guest Operating Systems

    Create a Linux guest operating system specification that you can apply when you create cloud templates for use with vRealize Automation. This customization specification can be used to customize virtual machine guest operating systems when provisioning new virtual machines from vRealize Automation.

  2. Create a Customization Specification for Windows Guest Operating Systems

    Create a Windows guest operating system specification that you can apply when you create cloud templates for use with vRealize Automation. This customization specification can be used to customize virtual machine guest operating systems when provisioning new virtual machines from vRealize Automation.

Create a Customization Specification for Linux Guest Operating Systems

Create a Linux guest operating system specification that you can apply when you create cloud templates for use with vRealize Automation. This customization specification can be used to customize virtual machine guest operating systems when provisioning new virtual machines from vRealize Automation.

UI Procedure

  1. Log in to vCenter Server at https://<vcenter_server_fqdn>/ui with a user assigned the Administrator role.

  2. Select Menu > Policies and profiles.

  3. In the left pane, click VM customization specifications.

  4. On the VM customization specifications page, click the Create a new specification icon.

    The New VM guest customization wizard opens.

  5. On the Name and target OS page, configure the settings and click Next.

    Setting Example Value
    Name linux-ubuntu-server-lts
    Description Ubuntu Linux Server LTS
    vCenter Server sfo-w01-vc01.sfo.rainpole.io
    Target guest OS Linux

  6. On the Computer name page, configure the settings and click Next.

    Setting Example Value
    Use the virtual machine name Selected
    Domain name sfo.rainpole.io

  7. On the Time zone page, configure the settings and click Next.

    Setting Example Value

    Hardware clock set to Local time

  8. On the Customization script page, click Next.

  9. On the Network page, click Next.

  10. On the DNS settings page, leave the default settings, and click Next.

  11. On the Ready to complete page, review the settings and click Finish.

  12. If you want to add more Linux customization specifications, repeat this procedure for each additional Linux customization specification.

  13. Repeat this procedure for each VI workload domain vCenter Server in each VMware Cloud Foundation instance.

PowerShell Procedure

  1. Start Windows PowerShell.

  2. Define the environment variables by running the following commands.

    $vCenterFqdn = "sfo-w01-vc01.sfo.rainpole.io"
$vCenterUser = "administrator@vsphere.local"
$vCenterPass = "VMw@re1!"

$customizationName = "linux-ubuntu-server-lts"
$customizationDescription = "Linux Ubuntu server LTS"
$osType = "Linux"
$domain = "sfo.rainpole.io"
$timeZone = "America/Los_Angeles"

    For a list of the acceptable values for $TimeZone for Linux customization specifications, see List of Time Zone Database Zones on Wikipedia or the IANA Time Zone Database.

  3. Connect to the VI workload domain vCenter Server and create a customization specification for a Linux guest operating system by running the following VMware PowerCLI cmdlets.

    Connect-VIServer -Server $vCenterFqdn -User $vCenterUser -Password $vCenterPass

New-OSCustomizationSpec -Name $customizationName -Description $customizationDescription -OSType $osType  -NamingScheme vm -Domain $domain  

$CustomizationSpec = Get-View -Id 'CustomizationSpecManager-CustomizationSpecManager'
$item = $CustomizationSpec.GetCustomizationSpec($customizationName)
$item.Spec.Identity.HwClockUTC = $false
$item.Spec.Identity.TimeZone = $timeZone
$CustomizationSpec.OverwriteCustomizationSpec($item)

  4. View the state of customization specification by running the following command.

    Get-OSCustomizationSpec -Name $customizationName | Format-List *

  5. Disconnect from the VI workload domain vCenter Server.

    Disconnect-VIServer -Server $vCenterFqdn -Confirm:$false

  6. If you want to add more Linux customization specifications, repeat this procedure for each additional Linux customization specification.

  7. Repeat this procedure for each VI workload domain vCenter Server in each VMware Cloud Foundation instance.

Create a Customization Specification for Windows Guest Operating Systems

Create a Windows guest operating system specification that you can apply when you create cloud templates for use with vRealize Automation. This customization specification can be used to customize virtual machine guest operating systems when provisioning new virtual machines from vRealize Automation.

UI Procedure

  1. Log in to vCenter Server at https://<vcenter_server_fqdn>/ui with a user assigned the Administrator role.

  2. Select Menu > Policies and profiles.

  3. In the left pane, click VM customization specifications.
