摘要： A source virtual machine (VM) hosted on a source server is migrated to a destination VM on a destination server without first powering down the source VM. After optional pre-copying of the source VM's memory to the destination VM, the source VM is suspended and its non-memory state is transferred to the destination VM; the destination VM is then resumed from the transferred state. The source VM memory is either paged into the destination VM on demand, or is transferred asynchronously by pre-copying and write-protecting the source VM memory, and then later transferring only the modified pages after the destination VM is resumed. The source and destination servers preferably share common storage, in which the source VM's virtual disk is stored; this avoids the need to transfer the virtual disk contents.

摘要： Techniques for creating a fault tolerant system in a virtual machine environment utilize a primary VM and a backup VM. To initialize the fault tolerant system, the backup VM and primary VM start from the same state. To achieve this in one embodiment, the primary VM is suspended and the state of the primary VM is copied to the backup VM. Once the backup VM has received all the primary VM's state, the primary VM is resumed. Subsequent state changes of the primary VM are buffered until the backup VM resumes, connects to the primary VM, and starts consuming the buffered content. Thereafter, synchronization is maintained by the primary VM's writing relevant state changes to a log and the backup VM's reading such relevant state changes from the log.

摘要： To generate a checkpoint for a virtual machine (VM), first, while the VM is still running, a copy-on-write (COW) disk file is created pointing to a parent disk file that the VM is using. Next, the VM is stopped, the VM' s memory is marked COW, the device state of the VM is saved to memory, the VM is switched to use the COW disk file, and the VM begins running again for substantially the remainder of the checkpoint generation. Next, the device state that was stored in memory and the unmodified VM memory pages are saved to a checkpoint file. Also, a copy may be made of the parent disk file for retention as part of the checkpoint, or the original parent disk file may be retained as part of the checkpoint. If a copy of the parent disk file was made, then the COW disk file may be committed to the original parent disk file.

摘要： A system and method for aligning prior patterning positions formed by a first SPM tip with a second SPM tip in combination with an SPM system includes identifying first location information that includes a location of the first SPM tip and a sample reference location on an SPM sample and storing the first location information in a storage area. After replacing the first SPM tip with the second SPM tip, second location information, which includes a location of the second SPM tip and the sample reference location on the SPM sample, is identified. Displacement is calculated between the location of the second SPM tip and the first SPM tip based on the first and second location information, and either the second SPM tip or a stage supporting the SPM sample is translated to align the second SPM tip with the location of the first SPM tip in accordance with the calculated displacement.
