A computer system generates snapshot backups of a virtual machine by creating a metadata snapshot and a backup snapshot. The computer system identifies a backup request for a virtual machine operating on a host computing system, initiates a backup snapshot of storage devices in use by the virtual machine, generates a metadata snapshot of a configuration of the virtual machine, and maintains the metadata snapshot in a data store.

Virtual machine backup using snapshots and current configuration

A method for determining a label size and conditions for displaying a tooltip includes identifying a label object within a parent object, computing a label width of the label object based at least partially on a layout associated with the parent object, and computing a text width for text data associated with the label object. The method further includes determining a size relationship between the label width and the text width, and determining whether to enable display of a tooltip for the label object based at least partially on the size relationship.

Determining a label size and conditions for displaying a tooltip

A method for managing network failure identifying a plurality of hypervisors, each of the plurality of hypervisors being associated with a plurality of networks, and identifying a first network of the plurality of networks, wherein a first network role is assigned to the first network. The method further includes determining whether the plurality of hypervisors satisfies an unavailability condition, and, in response to determining that the plurality of hypervisors satisfies the unavailability condition, re-assigning the first network role of the first network to a back-up network.

Managing network failure using back-up networks

A virtualization manager receives a request to perform a command in a virtual machine system and executes a plurality of transactions associated with the command, each of the plurality of transactions comprising one or more operations executed on entities in the virtual machine system. The virtualization manager commits changes made to the entities in the virtual machine system as a result of the plurality of transactions to a management database for the virtual machine system. In addition, the virtualization manager generates a business entity snapshot corresponding to a first transaction of the plurality of transactions, the business entity snapshot comprising state information for one or more entities in the virtual machine system affected by the first transaction.

Database change compensation after a transaction commit

A computer system generates a clone of a virtual machine from a point-in-time snapshot backup by collapsing metadata snapshots and storage snapshots into a virtual machine image. The computer system identifies a clone request for a virtual machine, the clone request comprising a point-in-time reference, retrieves at least one metadata snapshot and at least one storage snapshot based on the point-in-time reference, combines the at least one metadata snapshot and the at least one storage snapshot into a virtual machine image, and provisions a new virtual machine based on the virtual machine image.
