An example method of hypervisor lifecycle management in a virtualized computing system having a cluster of hosts includes: receiving, from a user at a lifecycle manager executing in the virtualized computing system, identification of a seed host; obtaining, by the lifecycle manager, a software specification from the seed host, the software specification describing a running image of the hypervisor executing on the seed host; generating, by the lifecycle manager, a software image from metadata and payloads stored on the seed host; setting, by the lifecycle manager, a host desired state for the cluster based on the software specification; and storing, by the lifecycle manager, the software image in a software depot in association with the host desired state.

Recreating a software image from a host in a virtualized computing system

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.

Provisioning DPU management operating systems

An example method of creating a software image from software executing on a host in a virtualized computing system includes: obtaining, by an image generator executing in the virtualized computing system, an image metadata from the host, the image metadata describing a running image of a hypervisor executing on the host; identifying, from the image metadata, a plurality of software installation bundles (SIBs) used to install the running image on the host; obtaining, from the image metadata, SIB descriptors and SIB signatures for the plurality of SIBs; obtaining, from storage on the host, payloads referenced in the image metadata for the SIBs; and recreating the plurality of SIBs from the SIB descriptors, the SIB signatures, and the payloads.

Recreating software installation bundles from a host in a virtualized computing system

An example method of managing a lifecycle of virtualization software in a host is described. The method includes: obtaining, by an initiator in a current version of the virtualization software, a software installation bundle (SIB) from an image repository for a target version of the virtualization software, the SIB including a patcher; verifying, by the initiator, authenticity of the SIB; mounting at least one payload of the SIB in a root filesystem of the virtualization software, and initiating, by the initiator, the patcher in the at least one payload as mounted to perform at least one check operation.
