An administrator needs to configure a VM with UEFI.

When using Nutanix IPAM (Managed Network) for DHCP, the built-in DHCP service has limitations regarding UEFI PXE boot support (specifically regarding the dynamic delivery of architecture-specific boot files like bootx64.efi vs undionly.kpxe).

To successfully provision UEFI VMs in this scenario—particularly for Citrix Provisioning Services (PVS)—the BDM (Boot Device Manager) ISO (referred to here as SDM boot ISO due to common industry acronym variance in exam banks) is required. The BDM ISO allows the VM to boot directly from a virtual CD-ROM that contains the bootstrap information needed to contact the provisioning server, bypassing the limitations of the IPAM PXE implementation for UEFI workloads.
