OS Installation Media

The options for OS installation media and boot mode available on the Installation Media page of the New VM wizard depend on the OS or template that you selected on the first page of the wizard.

OS installation media options

Install from ISO library or DVD drive

Templates: Windows and Linux guests

Select Install from ISO library or DVD drive and then choose an ISO image or a DVD drive from the list.

If the ISO image you want to use is not listed here, click New ISO library and create an ISO SR using the New Storage Repository wizard. After creating the ISO SR, you can select it from the list of available ISO libraries here.

If there are no ISO images listed here, you need to make the ISOs available to the server by creating an external NFS or SMB/CIFS share directory.

Boot from network

Templates: Windows and Linux guests

Select this option to use PXE/network booting for guests.

Selecting this option places the network at the top of the boot order for the new VM.

Boot mode

Choose a boot mode for the VM. Specify the boot mode when you create a VM. It is not possible to change the boot mode after booting the VM for the first time.

  • Select BIOS Boot to boot the VM in legacy BIOS mode.

  • Select UEFI Boot to boot the VM in UEFI mode.

  • Select UEFI Secure Boot to boot the VM in UEFI Secure Boot mode.

The most secure boot mode is selected by default. You can only select those boot options that are available to your new VM.

UEFI boot and UEFI Secure Boot are supported only on certain operating systems. For more information, see Guest UEFI boot and Secure Boot.

vTPM

You can attach a vTPM to some Windows guests by using the option Create and attach a new vTPM.

  • A vTPM is required for a Windows 11 VM. The option is selected and cannot be unselected.
  • Windows 10 VMs also support vTPM. You can choose whether to attach a vTPM. Attach a vTPM to your Windows 10 VM before upgrading the operating system to Windows 11.
  • The vTPM provides a TPM 2.0 compliant API to applications in the VM. TPM 1.2 is not supported.

For more information, see vTPM.
