Disclosed is an improved approach to implement I/O and storage device management in a virtualization environment. According to some approaches, a Service VM is employed to control and manage any type of storage device, including directly attached storage in addition to networked and cloud storage. The Service VM implements the Storage Controller logic in the user space, and can be migrated as needed from one node to another. IP-based requests are used to send I/O request to the Service VMs. The Service VM can directly implement storage and I/O optimizations within the direct data access path, without the need for add-on products.

Architecture for managing I/O and storage for a virtualization environment

Methods, systems, and techniques for facilitating access to content stored remotely, for example, as part of a virtual machine infrastructure or elsewhere in a networked environment, using a uniform mechanism are provided. Example embodiments provide an Enhanced Virtual Desktop Management Server/System with a Content Abstraction Layer which enables users to access their data stored as part of a virtual machine environment, or replicated otherwise on a network, using a generic API. The API can be incorporated into a web browser or other third party interface to provide access to the users' data without needing to remote a bitmap representation of a virtual desktop display. Accordingly, users can access their data, applications, and settings regardless of the type of access device and regardless of whether the corresponding virtual desktop is running in the data center, provisioned in the datacenter but running on a client device, or not running at all.

Independent access to virtual machine desktop content

The claimed subject matter provides a system and/or a method that facilitates securing a wireless digital transaction. A terminal component can receive a portion of data related to a payment for at least one of a good or a service. A mobile device can include at least one mobile payment card (m-card), wherein the m-card is created by establishing a link to an account associated with a form of currency. The mobile device can employ public-key cryptography (PKC) to securely and wirelessly transmit a payment to the terminal component utilizing the m-card and linked account.

Disclosed is an improved approach for using advanced metadata to implement an architecture for managing I/O operations and storage devices for a virtualization environment. According to some embodiments, a Service VM is employed to control and manage any type of storage device, including directly attached storage in addition to networked and cloud storage. The advanced metadata is used to track data within the storage devices. A lock-free approach is implemented in some embodiments to access and modify the metadata.

Metadata for managing I/O and storage for a virtualization environment

A remote browsing process is directed to the generation and management of a remote persistent browsing context at a network computing provider. A client computing device requests a remote persistent browsing context instance at a network computing provider. The network computing provider provides processing results corresponding to processed representations of requested content to the client computing device. The persistent browsing context may be maintained at the network computing provider subsequent to the user ending his interaction with the browser application at the client device. A client computing device may subsequently request access to the persistent browsing context maintained at the network computing and storage device.

Accessing virtual disk content of a virtual machine using a control virtual machine

Accessing virtual disk content of a virtual machine without running a virtual desktop

A method for managing storage for a desktop pool is described. The desktop pool includes a plurality of virtual machines (VMs), each VM having at least one virtual disk represented as a virtual disk image file on one of a plurality of datastores associated with the desktop pool. To identify a target datastore for a VM, a weight of each datastore is calculated. The weight may be a function of a virtual capacity of the datastore and the sum of maximum sizes of all the virtual disk image files on the datastore. The virtual capacity is a product of the data storage capacity of the datastore and an overcommit factor assigned to the datastore. The target datastore is selected as the datastore having the highest weight. The VM may is moved to or created on the target datastore.

VDI Storage overcommit and rebalancing

A plurality of virtual machines (VMs) is established and maintained by virtualization software on one or more physical servers. Desktop management software operates to provide the VMs to remote users as virtualized desktops. The desktop management software includes a rule engine that can be used to automate the policies of the organization. The rule engine manages the data center by controlling virtual infrastructure operations, such as power-on, power-off, suspension, and migration operations. The rule engine uses an event-condition-action paradigm, wherein an event causes a virtual infrastructure operation, possibly contingent on a condition. The rule engine provides for time-based scheduling of events in addition to system-based operations, which are triggered by events such as user logon and user logoff. The rule engine may also include the ability to automate the process of changing the properties of the virtual machines in a timely fashion.
