VM Template and BIOS Options

Various different VM templates are supplied with Citrix Hypervisor. These templates can be used in different ways to create VMs. Each template contains installation metadata: the information used to create a VM with a specific guest OS with the optimum storage, CPU, memory, and virtual network configuration.

For a full list of guest operating systems that Citrix Hypervisor supports, see Guest operating system requirements.

You can also create your own customized templates configured with the appropriate guest operating system, memory, CPU, storage, and network settings. For more information, see Creating new templates.

Select a BIOS option

Citrix Hypervisor VMs can be BIOS-generic or BIOS-customized:

BIOS-generic: the VM has generic Citrix Hypervisor BIOS strings;

BIOS-customized: HVM VMs support customization of BIOS in two ways, namely: Copy-Host BIOS strings and User-Defined BIOS strings.

  • Copy-Host BIOS Strings: The VM has a copy of the BIOS strings of a particular server in the pool.
  • User-Defined BIOS Strings: The user has option to set custom values in selected BIOS strings using CLI/API.

Note:

If a VM does not have BIOS strings set when it starts, the standard Citrix Hypervisor BIOS strings are inserted into it, and the VM becomes BIOS-generic.

For more information, refer to Advanced VM information.

When you create a VM using the New VM wizard, you can copy the BIOS strings from an OEM server in the same pool into the new VM. This action enables you to install Reseller Option Kit (BIOS-locked) OEM versions of Windows on the VM later, if needed. The OEM server from which you copy the BIOS strings is nominated as the home server for the new VM.

BIOS-customized VMs can be migrated, imported, and exported to servers with the same BIOS strings and to servers with different BIOS strings.

Important:

It is your responsibility to comply with any EULAs governing the use of any BIOS-locked operating systems that you install.
