Examples described herein includes initialization of a computing node cluster. An example method providing a query request from an initialization application/service of a computing node for a default configuration management server identifier via a network, and receiving, from a network management server, an internet protocol address associated with the default configuration management server identifier. The example method further includes providing a configuration request from the computing node to the internet protocol address requesting configuration information, and receiving the configuration information at the computing node from a configuration management server associated with the internet protocol address.

Apparatuses and methods for zero touch computing node initialization

Examples described herein include imaging servers which may support asynchronous imaging of one or more computers (e.g., computing nodes). The imaging server may use out-of-band communication to install requested images on one or more computing nodes. The imaging server may support multiple concurrent installation sessions, and may maintain a log specific to each session. This may facilitate session-specific status reporting. In this manner, operating systems, hypervisors, or other software may be installed on computing nodes.

Asynchronous imaging of computing nodes

In one embodiment, a system for managing communication connections in a virtualization environment includes (1) a first host machine implementing a virtualization environment based on a first platform, wherein the first host machine includes a first hypervisor, at least one virtual machine, and one or more virtual infrastructure elements and (2) a virtual disk including a plurality of storage devices. A management module for the system may perform steps to convert the first host machine to a second platform by installing (on the first host machine) a second hypervisor associated with the second platform, disabling the first hypervisor, capturing a configuration describing elements of a virtual infrastructure associated with the first hypervisor, registering the captured configuration with the second hypervisor, creating elements of the captured configuration in the context of the second platform and in association with the second hypervisor, and then enabling the second hypervisor.

Hypervisor conversion

Systems and methods for deploying and managing virtual machine clusters. A method commences upon launching, on a subject processor instance that is running a first operating system, an installation hypervisor that forms a RAM disk comprising an installation boot image and respective one or more scripts. A bootable portion of the RAM disk is exposed to a virtual machine so as to serve as a virtual boot device that comprises the installation boot image and its one or more scripts. Next, a physical boot device is exposed to the virtual machine so as to initiate a boot operation that causes the virtual machine to boot. A subsequent boot operation is initiated to cause transfer of instruction execution to a low-level I/O subsystem entry point such that the target boot image is booted.
