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 PV and HVM 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 HVM guests

Select this option to use PXE/network booting for HVM guests and Other install media templates.

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

Install from URL

Templates: Linux PV guests

You can install PV versions of CentOS, SUSE Linux Enterprise Server, and Red Hat Linux operating systems from a network install repository. Select Install from URL and enter a URL which must include the server IP address and the repository path in the following form:

nfs://server/path
ftp://server/path
http://server/path

For example: nfs://10.10.32.10/SLES10, where 10.10.32.10 is the IP of the NFS server and /SLES10 is the location of the install repository.

You can also optionally provide more operating system boot parameters, if necessary.

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. Boot options that are not available to your new VM cannot be selected.

UEFI boot and UEFI Secure Boot are supported only on newly created Windows 10 (64-bit), Windows Server 2016 (64-bit), and Windows Server 2019 (64-bit) VMs. For more information, see Windows VMs.
