  • Patent number: 12282795
    Abstract: Upon receiving a request to hibernate a hypervisor of a virtualization system running on a first computer, acts are carried out to capture a state of the hypervisor, where the state of the hypervisor comprises hypervisor logical resource parameters and an execution state of the hypervisor. After hibernating the hypervisor by quiescing the hypervisor and storing the state of the hypervisor into a data structure, the data structure is moved to a different location. At a later moment in time, the data structure is loaded onto a second computing machine and restored. The restore operation restores the hypervisor and all of its state, including all of the virtual machines of the hypervisor as well as all of the virtual disks and other virtual devices of the virtual machines. Differences between the first computing machine and the second computing machine are reconciled before execution of the hypervisor on the second machine.

  • Patent number: 12267257
    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.

  • Patent number: 12259790
    Abstract: A high frequency snapshot technique improves data replication in a disaster recovery (DR) environment. A base snapshot is generated from failover data at a primary site and replicated to a placeholder file at a secondary site. Upon commencement of the base snapshot generation and replication, incremental light weight snapshots (LWSs) of the failover data are captured and replicated to the secondary site. A staging file at the secondary site accumulates the replicated LWSs (“high-frequency snapshots”). The staging file is populated with the LWSs in parallel with the replication of the base snapshot at the placeholder file. At a subsequent predetermined time interval, the accumulated LWSs are synthesized to capture a “checkpoint” snapshot by applying and pruning the accumulated LWSs at the staging file. Once the base snapshot is fully replicated, the pruned LWSs are merged to the base snapshot to synchronize the replicated failover data.

  • Patent number: 12259794
    Abstract: A technique enables coordination of unrelated software components to facilitate extensive recovery point management on a snapshot or recovery point through the use of a flexible tag structure. The tag is organized and arranged as a {key=value,[value] . . . } structure wherein the key denotes an operation that requires coordination between the unrelated software components and the value(s) denote multi-cardinality that provide parameters for coordination of the operation. The multi-cardinality aspect of the flexible tag structure provides a set of values associated with the key of the tag that enables a software component and/or protocol to insert its value(s) into the tag structure for its interpretation. The technique thus provides an extensible model where multiple components/protocols use the tag to coordinate operations on the RP by conveying certain meaning/interpretations of the tag and its values.

  • Patent number: 12255769
    Abstract: A recovery orchestration pipeline has stages configured to control efficient failover and recovery of applications in a multi-site disaster recovery (DR) environment. The applications run on user virtual machines (UVMs) at a primary site of the DR environment and connect to block storage devices (BSDs) that export virtual disks over a storage protocol to consume data including a recovery plan for disaster recovery. The recovery plan includes a recovery configuration whose generation is triggered by a user via a graphical user interface (GUI) and specifies resource requirements needed to recover the applications at a secondary site in the event of a disaster. The orchestration pipeline is initiated via single click of the GUI and completion of the stages of the pipeline is displayed as progress via the GUI to allow recovery of the applications without user intervention.

  • Patent number: 12255811
    Abstract: Methods, systems, and computer program products for computer networking. Legacy policy-based routing is advanced by adding fallback-aware policy actions that are enabled within a policy-based routing regime. Upon determining that a destination specified in a subject policy is compromised, or down, or unreachable then, a fallback-aware policy action is invoked. Destinations specified in policies may refer to inserted services, wherein an inserted service can be any one of, a service process, a service virtual machine, a hardware network component, or a virtual network interface. Such inserted services might implement a logging service, or a firewall service, or other services that can process a network packet. Fallback-aware policy actions include, a PASSTHROUGH fallback action, an ALLOW fallback action, a FORWARD fallback action, and a DROP fallback action. Various techniques serve to determine whether or not a particular destination of a subject policy is deemed to be compromised, or down or unreachable.

  • Publication number: 20250086295
    Abstract: Examples described herein are generally directed towards file server access controls, and more specifically towards a mechanism to create consistent access control lists for local users across different file servers in a distributed file server environment. In operation, a local user system SID (e.g., external SID) may be generated for a first user of a first file server. A global ID based on attributes associated with the user of the first file server may also be generated. The global ID for the user may be stored in metadata associated with an access control list (ACL) for a file accessible through the first file server. Data, including the file may be migrated to a second file server. Based on receiving an access request at the second file server associated with the user based on the external ID, the external ID for the user may be translated into the global ID, and used to determine access to the file.

  • Publication number: 20250085975
    Abstract: Bootstrapping a microservices container registry. A computing system node receives an installation package. The receiving computing system node bootstraps an initial invocation of the microservice by first installing a local container registry from the installation package and then by installing the microservice from the installation package. The installation package contains additional components that can be extracted, installed and invoked by executing the microservice at the computing system node after extracting from the local container registry. The installation package is generated by any node of the computing system and contains code corresponding to infrastructure microservices that are installed before invoking microservices that depend on the infrastructure. Temporary domain name services are installed from the installation package at a node-local IP address. The temporary domain name services are switched over to a different domain name service at a different IP address.

  • Publication number: 20250077368
    Abstract: Placement scenario optimization mechanisms for automatic placement of computing entities onto nodes of a running multi-node computing cluster. A set of failure mode parameters define a high-availability requirement of the multi-node computing cluster. In advance of a failure event, and responsive to a determination that a then-current computing entity placement does not satisfy the high-availability requirement, the cluster is analyzed and a plurality of feasible placement scenarios are generated. Optimization criteria are applied to the feasible placement scenarios such that a best choice from among the feasible placement scenarios is identified and applied to the virtual machine placements over the cluster. A change monitoring and detection facility continually observes the multi-node computing cluster to detect a change of a failure mode parameter or to detect a change to the configuration of the virtual machines.
