| 20080270674 | Adjusting Available Persistent Storage During Execution in a Virtual Computer System - The amount of virtual disk space that is available for use by software executing within a virtual machine may be dynamically adjusted while the virtual machine is running in a virtual computer system. According to one aspect, a method for flexible run-time reservation of disk space from a virtual machine is provided. The method includes designating for use by a first virtual machine, a fixed portion of disk space accessible by a computing system. The first virtual machine is activated. During operation of the first virtual machine, a portion of the fixed portion of the disk space designated for use by the first virtual machine is reserved from within the first virtual machine. Use of the reserved portion is controlled from outside of the first virtual machine. | 10-30-2008 |

| 20090328225 | System and Methods for Enforcing Software License Compliance with Virtual Machines - A virtualization system supports secure, controlled execution of application programs within virtual machines. The virtual machine encapsulates a virtual hardware platform and guest operating system executable with respect to the virtual hardware platform to provide a program execution space within the virtual machine. An application program, requiring license control data to enable execution of the application program, is provided within the program execution space for execution within the virtual machine. A data store providing storage of encrypted policy control information and the license control data is provided external to the virtual machine. The data store is accessed through a virtualization system including a policy controller that is selectively responsive to a request received from the virtual machine to retrieve the license control data dependent on an evaluation of the encrypted policy control information. | 12-31-2009 |
| 20100107158 | LOW OVERHEAD FAULT TOLERANCE THROUGH HYBRID CHECKPOINTING AND REPLAY - A virtualized computer system provides fault tolerant operation of a primary virtual machine. In one embodiment, this system includes a backup computer system that stores a snapshot of the primary virtual machine and a log file containing non-deterministic events occuring in the instruction stream of the primary virtual machine. The primary virtual machine periodically updates the snapshot and the log file. Upon a failure of the primary virtual machine, the backup computer can instantiate a failover backup virtual machine by consuming the stored snapshot and log file. | 04-29-2010 |

| 20100162235 | VIRTUALIZATION SYSTEM WITH A REMOTE PROXY - A remote proxy provides remote control to a virtualization system. The virtualization system includes a computer having virtualization software executing on the computer, and one or more virtual machines executing on the computer by way of the virtualization software, each of the virtual machines having a guest operating system. The remote proxy receives over a network connection a plurality of logical channels of a multi-channel remote control protocol at a first domain of a plurality of domains of the virtualization system. Each of the logical channels convey information corresponding to one of the domains. For each logical channel, the remote proxy identifies the corresponding domain. Further, for each of the logical channels corresponding to a domain other than the first domain, the remote proxy forwards the logical channel to the corresponding domain. | 06-24-2010 |
| 20100191845 | SPECULATIVE VIRTUAL MACHINE RESOURCE SCHEDULING - A speculative virtual machine (“VM”) resource scheduler for a VM that is hosted by a primary host server initiates the creation of at least one duplicate VM on a secondary host server. The VM and the duplicate VM are run substantially in lockstep while the scheduler monitors resources on the primary host server and the secondary host server. The scheduler then determines an advantageous host server among the primary host server and the secondary host server and, based at least in part on the determination, initiates the powering down of either the VM on the primary host server or the duplicate VM on the secondary host server. | 07-29-2010 |
