  • Transitioning of virtual machine from replay mode to live mode
    Patent number: 7966615
    Abstract: A backup VM is allowed to enter live execution mode at instruction boundaries but not in the middle of emulation of a single instruction. This is accomplished by having the last log entry of multiple entries generated during emulation of an instruction to have an indication of a “go-live” point and by having the backup VM not replay log entries provided by the primary VM beyond the log entry that indicates the “go-live” point.

  • Identification features
    Publication number: 20100294844
    Abstract: Methods for providing pharmaceutical compositions and objects with identification regions and identification features which are difficult to detect. Microlithography, nanolithography, and stamping methods are used. The identification features can be positive protrusions or negative indentations with respect to the surface. The identification regions can comprise bar codes and holograms. DPN printing or other lithographies such as electron beam lithography, optical lithography, or nanoimprint lithography can be used to prepare stamps, which are then used to prepare the identification features. Redundant patterns can be formed. The invention is useful for counterfeit prevention. An apparatus for stamping the identification features is also described.

  • Storage handling for fault tolerance in virtual machines
    Patent number: 7840839
    Abstract: A fault-tolerant virtualized computer system comprises a primary host executing a primary virtual machine (VM) and a backup host executing a backup VM. In one embodiment, each VM includes a virtual disk mapped to a shared disk image on physical disk accessible to both hosts. A virtual disk IO request is received by virtualization software executing on the backup host from a backup VM. When the virtual disk IO request is a read request, the virtual disk IO request is mapped to a physical read IO request of a virtual disk image stored on a physical disk, the physical read IO request is issued to the physical disk. However, when the virtual disk IO request is a write request, it is assumed to be completed without mapping the virtual disk IO request or issuing a mapped physical IO request to the physical disk.

Hydrophilicity and hydrophobicity can be used to control ink flow. SEM can be used to characterize the inkwells. Ink flow can be monitored with video. Hydrophobic material layers can be used to prevent cross contamination. Microsyringes can be used to fill reservoirs. Satellite reservoirs can be used to prevent bubble formation.

  • Virtual Machine Migration
    Publication number: 20100169537
    Abstract: 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 in to 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.

  • Sequential equivalent—time sampling with an asynchronous reference clock
    Patent number: 7746058
    Abstract: A sequential equivalent-time sampling oscilloscope simultaneously acquires samples of a signal-under-test and a reference clock that is asynchronous with the signal-under-test. The oscilloscope converts the samples of the reference clock into timestamps and uses the timestamps to compensate for the jitter of the oscilloscope and to indicate the absolute jitter of the signal-under-test.

  • Generating and Using Checkpoints in a Virtual Computer System
    Publication number: 20100122052
    Abstract: 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.
