Abstract: Methods, systems and computer program products for hibernating a computing cluster. An information lifecycle manager facility (ILM) is invoked to carry out movement of data from the hypervisor of a node of a computing cluster to a different storage location. Multiple nodes of the computing cluster can be hibernated until the entire computing cluster has been hibernated. The ILM observes a replication factor of the computing cluster to suppress saving multiple copies of data. A hibernation object comprising state information of a node is stored in a network-accessible storage location. The hibernation object is accessed in response to an instruction to initiate restoration of all or parts of the computing cluster. The hibernation object can be stored using first cloud computing storage infrastructure and later, can be restored to a different cloud computing infrastructure. Upon restoration, the hibernated cluster has the same state as of the time of hibernation.

Abstract: Methods, systems, and computer program products for executing trusted software components in public computing clouds. Verifiably authentic software components are installed into a tenant partition of a multi-tenant public cloud-based environment. To do so, a software component installer is configured to install registered software components into the tenant partition. Installer processing includes (1) obtaining a component-specific token for a software component wherein the component-specific token is specific to both the software component to be installed and a particular tenant, and (2) installing the software component on behalf of the given tenant in the multi-tenant public cloud-based environment. Prior to executing the underlying code of the tenant-specific software component, the software component is authenticated with a component registry using the component-specific token. Additional trusted components are installed based on demand from within the tenant partition.

Abstract: Disclosed is an improved approach for managing floating/virtual IP addresses in a virtualization system. Where a bare metal cloud provider does not provide adequate facilities to implement broadcast operations, the approach would capture broadcast packets, and from the captured packets, generate calls to the cloud provider to implement configuration changes to reflect the changes desired by the broadcast packets.

Abstract: Methods, systems and non-transitory computer readable media for handling IP network addresses in a virtualization system. Embodiments are configured to receive, from a cloud provider, a cloud provider media access control address to assign to a network interface of a computing node. Also received from the cloud provider is a cloud provider's IP address associated with the cloud provider's media access control address. A virtual machine on the computing node is configured such that the cloud provider's IP address serves as an IP address of the virtual machine and such that a virtualization system media access control address serves as a MAC address of the virtual machine. The virtualization system correlates the cloud provider's media access control address to the IP address of the virtual machine. In some cases, the cloud provider's media access control address stored in a virtual switch of a hypervisor.

Abstract: Methods, systems and computer program products for configuring private cloud computing resources to run a workload in the execution context of a dynamically configured virtualization system. Embodiments commence upon receiving a computing workload demand specification from a resource demander. The workload demand specification is delivered to a brokerage service. The brokerage service in turn identifies an available computing resource of a private cloud provider that matches up with the received computing workload demand specification. A virtualization system that is dynamically configured for the specified workload is installed on some or all of the available computing resources of the private cloud provider. Once the virtualization system is configured, installed and able to accept a workload for execution, the computing workload is scheduled to run in the virtualization system.

Abstract: Methods, systems and computer program products for deploying a virtualization system onto cloud computing infrastructure. Virtual machines of a virtualization system are deployed onto computing nodes that are interconnected via a cloud provider's networking infrastructure. When migrating a virtual machine from a source computing node to a target computing node that is also interconnected to the cloud provider's networking infrastructure, the addressing of the to-be-migrated virtual machine changes. Dynamically-updated media access control translation tables are maintained at the computing nodes. The media access control translation tables are populated with cloud provider media access control addresses received from the cloud provider. A virtual switch at each computing node modifies incoming and outgoing packets of a to-be-migrated virtual machine based on contents of that node's media access control translation table.

Abstract: Computing device file system change detection and change replication methods and systems are described herein. In one embodiment, the change detection is accomplished by comparing two master file tables of two different versions of the same file system and inferring file system name space change, file system metadata change and file data change.

The method also includes replicating these change logs to the replication server and applying the change logs to the data store on replication server.
