Techniques for dynamic disk personalization
View Patent ↗Techniques for dynamic disk personalization are provided. A virtual image that is used to create an instance of a virtual machine (VM) is altered so that disk access operations are intercepted within the VM and redirected to a service that is external to the VM. The external service manages a personalized storage for a principal, the personalized storage used to personalize the virtual image without altering the virtual image.
1. A method implemented and residing within a computer-readable storage medium that is executed by a processor of a network to perform the method, comprising:
receiving a disk access request, the disk access request originating from within a virtual machine (VM) defined by a virtual image, the disk access request including a principal identifier for a principal that originated the disk access request within the virtual image and the disk access request including a resource identifier for a resource associated with the disk access request;
searching an index for the principal identifier and the resource identifier to identify a location for handling the disk access request; and
returning to the virtual image completion notification for the disk access request and data to fulfill the disk access request;
the method processing external to the processing of the virtual image.
2. The method of claim 1 , wherein receiving further includes acquiring the disk access request from a dynamic storage filter configured within the virtual image, the dynamic storage filter intercepts the disk access request in a manner that is transparent to the principal and externally redirects the disk access request to the method.
3. The method of claim 1 , wherein searching further includes querying a global index with the principal identifier to locate the index for the principal and then querying the index with the resource identifier to obtain the location.
4. The method of claim 1 , wherein searching further includes enforcing a policy to resolve the index that is searched, the policy enforced based on the principal identifier.
5. The method of claim 4 , wherein enforcing further includes assigning a role for the principal based on the principal identifier and using the assigned role to locate the index within a hierarchy of indexes.
6. The method of claim 1 , wherein returning further includes providing the virtual image with the location that is defined within an external personalized storage for the principal, the external personalized storage is external to the virtual image and is used for customizing and personalizing the virtual image for the principal.
7. The method of claim 1 , wherein returning further includes providing the virtual image with the location that is defined within the virtual image and that was originally present on the virtual image when the disk access request was originated by the principal.
8. A multiprocessor-implemented system, comprising:
a dynamic virtual image storage filter implemented in a computer-readable storage medium and to execute on a processor within a virtual machine (VM); and
a virtual image customization service implemented in a computer readable medium and to execute on another processor that is external to the VM;
the dynamic virtual image storage filter is configured to intercept disk access operations made within the VM and dynamic virtual image storage filter further configured to redirect those disk access operations to the virtual image customization service, the virtual image customization service configured to locate storage, resources, and data that satisfy the disk access operations and the virtual image customization service further configured to define for the dynamic virtual image storage filter mechanisms for processing the disk access operations within the VM based on resolved locations for the storage, the resources, and the data.
9. The system of claim 8 , wherein the dynamic virtual image storage filter is configured as part of a virtual image for the VM and is configured to initiated when the VM is executed.
10. The system of claim 8 , wherein the virtual image customization service is configured to handle and process the disk access operations for the VM and other disk access operations for multiple other VM's of a network.
11. The system of claim 8 further comprising, an identity service implemented in a computer-readable storage medium and to execute on another processor, the identity service configured to interact with the virtual image customization service to provide authentication and security services when the virtual image customization service attempts to locate the storage, the resources, and the data.
12. The system of claim 8 further comprising, a personalized storage implemented in a computer-readable medium, the personalized storage customized for a particular identity of a particular principal, the virtual image customization service configured to access the personalized storage when processing the disk access operations to personalize the VM for the particular principal.
13. The system of claim 12 further comprising, an index implemented in a computer-readable storage medium, the virtual image customization service configured to search the index to identify and to access specific areas of the personalized storage.
