Abstract: Availability of a virtual machine is managed using a distributed key-value store. The distributed key-value store includes a first entry and a second entry. The first entry represents a definition of the virtual machine, and the second entry represents that a first node of the cluster hosts the virtual machine. Managing availability of the virtual machine includes detecting unavailability of the virtual machine. Managing availability of the virtual machine includes, responsive to detecting unavailability of the virtual machine, writing a task entry to the distributed key-value store to cause a second node of the cluster to create the virtual machine on the second node. Managing availability of the virtual machine includes rewriting the second entry so that the second entry represents that the second node hosts the virtual machine.

Abstract: Systems and methods that enable the optimal creation of a storage object within a virtual storage system are disclosed. In accordance with embodiments, an optimal location with the storage system is determined in response to receiving an indication that a storage object is to be created within the storage system. The system and method prioritize physical storage resources in which to create the storage object, prioritize components to be provided access to the created storage object, and prioritize the interface between the physical storage resources and the accessing component. The storage object is optimally created within the storage system based on the priorities and based, at least in part, on other created storage objects.

Abstract: Method and system for correcting misalignment between a virtual storage device block and a storage device block is provided. To align the blocks, an alignment module adjusts a logical block address and updates virtual storage device information such that a virtual machine can use a virtual storage device with the aligned blocks.

Abstract: A system and method for dynamically producing virtual machines (VMs) across a plurality of servers in the virtual server environment is provided. A single VM request queue is produced comprising VM requests for producing the plurality of VMs. A processing thread is produced and assigned for each server and retrieves VM requests from the VM request queue and produces VMs only on the assigned server according to the retrieved VM requests. Each processing thread may be configured for retrieving VM requests and producing VMs without any programmed delays, whereby the rate at which a processing thread produces VMs on its assigned server is a function of the performance capabilities of the assigned server. This dynamic allocation of VMs based on such a “natural selection” technique may provide an appropriately balanced allocation of VMs based on the performance capabilities of each server in the virtual server environment.
