Abstract: Disclosed are various examples of provisioning a data processing unit (DPU) management operating system (OS). A management hypervisor installer executed on a host device launches or causes a server component to provide a management operating system (OS) installer image at a particular URI accessible over a network internal to the host device. A baseboard management controller (BMC) transfers the DPU management OS installer image to the DPU device. A volatile memory based virtual disk is created using the DPU management OS installer image. The DPU device is booted to a DPU management OS installer on the volatile memory based virtual disk. The DPU management OS installer installs a DPU management operating system to a nonvolatile memory of the DPU device on reboot of the DPU device.

Abstract: Disclosed are various examples of provisioning a data processing unit (DPU) management operating system using a capsule. A management hypervisor installer executed on a host device receives a listing DPU device from a baseboard management controller (BMC). A preinstalled DPU management operating system image is identified for a DPU device from the listing, and is wrapped with a capsule that specifies the capsule as a DPU management operating system image capsule. A server component provides the DPU management operating system image capsule at a particular URI, and the URI is transmitted to the BMC.

Abstract: Disclosed are various embodiments for coordinating the rollback of installed operating systems to an earlier, consistent state. In response to determining that a data processing unit (DPU) installed on a computing device has failed to successfully boot a first time, the computing device can be power cycled for a first time. In response to determining that the DPU has successfully booted a second time, a first version of a host operating system can be booted. A DPU operating system (DPU OS) is then booted from a DPU alternate boot image. In response to determining that the first version of the host operating system fails to match an executing version of the DPU OS, the computing device can be power cycled a second time and the host operating system is then booted from a host alternate boot image.
