摘要： The present invention provides a virtual machine system and a method for sharing a graphics card amongst virtual machines. A VMM of the virtual machine system is provided with a resource-converting module, which converts data exchanged between a graphics card drive module of a GOS in the foreground and the graphics card based on a resource-converting table, and also intercepts accesses to the real graphics card by a GOS in the background and then responds to its operations on the graphics card. The VMM is further provided with a switching module, which alters a state of a VM based on a command for switching the VM, saves a graphics card state before the VM is switched to the background and restores the stored graphics card state to the graphics card when the VM is switched back to the foreground. Further, the GOSs each comprise a graphics card drive module corresponding to the real graphics card for accessing the real graphics card. The systems and the methods according to the present invention enable the GOSs to access the real graphics card, and also enable switching among a plurality of virtual machines.

摘要： A system and method for hybrid virtual machine monitor system is provided. A first operating system uses a file system to manage data storage and retrieval within a data storage area. A second operating system, which is not compatible with the first operating system's file system, executes a management application backup utility. The first operating system includes a filter driver that sends logical block addresses, which correspond to data reads/writes, to the management application backup utility. In turn, the management application backup utility uses the logical block addresses to perform operations on the data storage locations. In one embodiment, the management application backup utility performs actions on the data storage area, such as a disk defragmentation, and subsequently sends data location changes to the filter driver. In this embodiment, the filter driver instructs the first operating system's file system to update its translation tables based upon the data location changes.
