Abstract: The disclosure provides a method for preparing a simulation system to simulate upgrade operations for a distributed container orchestration system. The method generally includes monitoring, by a simulation operator of the simulation system, for new resources generated at a management cluster in the distributed container orchestration system, based on the monitoring, discovering, by the simulation operator, a new resource generated at the management cluster specifying a version of container orchestration software supported and made available by the management cluster, and triggering, by the simulation operator, a creation of a new mock virtual machine (VM) template in the simulation system specifying the version of the container orchestration software, wherein the simulation system is configured to use the new mock VM template for simulating mock VMs in the simulation system that are compatible with the version of the container orchestration software supported and made available by the management cluster.

Abstract: An example method of diagnosing remote sites of a distributed container orchestration system includes: receiving, at a management cluster, definition of a test suite custom resource; deploying, in response to the test suite custom resource, a first pod in the management cluster; deploying, by the first pod, a second pod in a server of a first remote site of the remote sites; checking, by the second pod, configuration of the server that includes an additional pod executing alongside the second pod, at least one virtual machine (VM) in which the second pod and the additional pod execute, a hypervisor configured to support the at least one VM, and a hardware platform on which the hypervisor executes; and returning test data from the second pod to the first pod, the test data including results of the step of checking the configuration of the server.

Abstract: The present disclosure provides example computer-implemented method, medium, and system for managing IP addresses for DPDK enabled network interfaces for cloud native pods. One example method includes creating a pod of one or more containers, where the pod connects to multiple networks through multiple network interfaces. A poll mode driver (PMD) is attached to a first network interface of the multiple network interfaces, where the PMD enables one or more data plane development kit (DPDK) applications inside the pod to manage the first network interface. A first container network interface (CNI) is created to handle the DPDK enabled first network interface. A first Internet protocol (IP) address is allocated to the first network interface using the first CNI. The first IP address is passed to the one or more DPDK applications using the first CNI.

Abstract: A computer-implemented method, medium, and system for upgrade of telco node cluster running cloud-native network functions are disclosed. In one computer-implemented method, a worker node group that includes a plurality of worker nodes is determined in a container orchestration platform. A first node to upgrade is determined within the worker node group. All pods in the first node are deactivated by a high availability as a service (HAaaS) module. Standby pods in a second node are activated by the HAaaS module and as active pods. All network traffic associated with all the pods in the first node is migrated to the active pods. The first node is deleted from the worker node group. Hardware resources associated with running the first node are released. A third node is generated as a new worker node in the worker node group and uses the released hardware resources.

Abstract: Virtualized computing instances, such as virtual machines, in a virtualized computing environment are provisioned using a tree-based template structure. The tree-based template structure includes a base node and multiple nodes linked to the base node. Each of the multiple nodes includes at least one component that represents a delta relative to the base node. By matching the requirements and role of a virtualized computing instance to be provisioned with the content(s) of a particular node, the particular node can be selected for cloning/creating the virtualized computing instance.

Abstract: System and methods for creating and configuring virtual machines (VMs) are provided. The method may include receiving, a first VM configuration and a second VM configuration. The second VM configuration is related to the first VM configuration. The method may include creating a first plurality of VMs in a first VM group based on the first VM configuration and creating a second plurality of VMs in the first VM group based on the second VM configuration. The method may further include applying the affinity rule in the first VM configuration to the first plurality of VMs and the second plurality of VMs. The method may further include configuring the first plurality of VMs based on the set of VM services in the first VM configuration and the second plurality of VMs based on the set of VM services in the second VM configuration.

Abstract: An information processing method is applied in a controlled device. The method includes: receiving an input operation for the control device to control a cursor of the controlled device, controlling the cursor to move at a first rate based on an input parameter of the input operation, and controlling the cursor to move at a second rate in a first region, the first rate being less than the second rate. An electronic device and an input device are also provided.
