A method includes deploying a containerized execution environment on a cluster of virtual machines and performing a snapshot on each virtual machine in the cluster of virtual machines to save a first version of the containerized execution environment on the cluster. The method further includes performing a test on the containerized execution environment and reverting each virtual machine of the cluster of virtual machines to the first version of the cluster saved by the snapshot in view of the test.

Recoverable container platform cluster for testing

A process in a system can monitor available free storage space on a storage device, and, based on preset log file parameters, can act upon log files being stored on or written to the storage device to keep the storage device from running out of storage space due to excessive logging. The process monitors the device free space as reported by the file system to determine space utilization. A threshold of free space can be specified as a parameter. A log file action can also be specified as a parameter and is an action designed to reduce the space being used by a log file or log files. Once the process recognizes that the free space is under the threshold it will perform the configured action.

Storage-based log file management

Systems and methods for managing containerized clusters from virtualization management systems. An example method may include identifying one or more cluster entities of a containerized computing cluster, where the containerized computing cluster comprises a plurality of virtual machines running on one or more host computer systems, generating one or more virtualization management entities in the virtualization management system, wherein each virtualization management entity represents a respective cluster entity, receiving a request to perform an operation on a specified virtualization management entity in the virtualization management system, identifying a cluster entity represented by the virtualization management entity, translating, responsive to the request, the request to one or more commands to be performed on the identified cluster entity of the containerized computing cluster, and sending the one or more commands to the containerized computing cluster.

A system and method for configuring components added to a network is disclosed. The method includes detecting, by a first hypervisor of a first host machine, that a second host machine having a second hypervisor is being added to a cluster of host machines comprising the first host machine, and identifying a plurality of network connections of the first hypervisor, each network connection being associated with one of a plurality of networks connecting hypervisors on host machines in the cluster, each network connection of the first hypervisor having a set of configuration settings. The method also includes generating, for each network connection, a message including a set of configuration settings of a corresponding network connection of the first hypervisor, and transmitting the message on a respective network to a second hypervisor to facilitate configuration of a corresponding network connection of the second hypervisor.

Virtual machines can be migrated between computing environments. For example, a system can receive a request to perform a migration process involving migrating a virtual machine from a source computing environment to a target computing environment. The target computing environment may be a cloud computing environment. In response to the request, the system can receive first configuration data for a first version of the virtual machine that is located in the source computing environment. The first configuration data can describe virtualized features of the first version of the virtual machine. The system can use the first configuration data to generate second configuration data for a second version of the virtual machine that is to be deployed in the target computing environment. The system can then deploy the second version of the virtual machine within one or more containers of the target computing environment in accordance with the second configuration data.

A shared debugging service stores information captured during software debug sessions for future use. The information can include developer identities so that future developers can contact past developers for assistance. The information can also include information such as developer steps, user settings, path-to-current code specifics, and stored breakpoint values. A developer can request a record of previous software debug sessions for a given piece of software and can acquire, store, or display previously collected information to assist in a current software debug session.

Shared software debugging service

A host system executing multiple virtual machines that is associated with multiple storage domains may be identified. Storage domain data may be received that includes utilization of each of the multiple storage domains by the multiple virtual machines. It may be determined that the utilization of a first storage domain of the multiple storage domains by the virtual machines satisfies a threshold utilization. In response to determining that the utilization of the first storage domain satisfies the threshold utilization, a second storage domain may be identified in view of a storage domain rank. An instruction may be provided to cause a storage migration of a virtual machine from the first storage domain to the identified second storage domain.
