Abstract: A method for processing packet data in a service provider environment includes, by a network-enabled data processing device within a server computer of the service provider environment, receive packet data including header information and payload information. The packet header information can be separated from the payload information. The separated header information can be forwarded to a processor of the server computer for processing, without forwarding at least a portion of the payload information. Transforming instructions and at least one address of one or more storage locations can be received from the processor, based at least in part on the header information. The payload information can be transformed based on the transforming instructions. The transformed payload information can be stored in the one or more storage locations based on the at least one address.

The interior includes a plurality of isotropically luminant surfaces and a substantially reflective surface. Further, the vehicle light assembly includes a light source arranged within the light chamber, and the light source is substantially oriented to emanate light that initially strikes the substantially reflective surface, propagates within the chamber along the isotropically luminant surfaces, and exits the chamber through the lens.

Abstract: A system provides remote computing services using physical or virtualized computing resource instances on various host machines. An enhanced PCIe endpoint card connected to a given host machine may include a local processor (e.g., on an SOC device) that emulates PCIe compliant hardware (e.g., a USB controller) in software. A client receiving computing services from the system may redirect USB traffic from a locally-attached physical USB device (e.g., an input/output, storage, or security device) over the Internet to the enhanced PCIe endpoint card. The enhanced PCIe endpoint card may present an emulated USB controller to an application executing on the host (on the client's behalf) as a device that is locally attached at the given host machine, and the application may access the functionality of the physical USB device by exchanging commands or data with the emulated USB controller through a PCIe controller on the enhanced PCIe endpoint card.

Abstract: A multi-phase boot operation of a virtualization manager at a virtualization host is initiated at an offload card. In a first phase of the boot, a security key stored in a tamper-resistant location of the offload card is used. In a second phase, firmware programs are measured using a security module, and a first version of a virtualization coordinator is instantiated at the offload card. The first version of the virtualization coordinator obtains a different version of the virtualization coordinator and launches the different version at the offload card. Other components of the virtualization manager (such as various hypervisor components that do not run at the offload card) are launched by the different version of the virtualization controller.

Abstract: Generally described, the present application relates to systems and methods for the managing virtual machines instances using a physical computing device and an offload device. The offload device can be a separate computing device that includes computing resources (e.g., processor and memory) separate from the computing resources of the physical computing device. The offload device can be connected to the physical computing device via a bus interface. The bus interface can be a high speed, high throughput, low latency interface such as a Peripheral Component Interconnect Express (PCIe) interface. The offload device can be used to offload virtualization and processing of virtual components from the physical computing device, thereby increasing the computing resources available to the virtual machine instances.

Abstract: Generally described, aspects of the present disclosure relate to offload device virtual component checkpointing for fast recovery from virtual component software crashes by storing virtual component state configuration information and input/output (I/O) request identification information in non-volatile memory of a physical computing device physically separate from the offload device. In the event of a software crash of a virtual component, the crashed virtual component may be rebooted and reconfigured in accordance with the virtual component state configuration information and I/O request identification information stored in the non-volatile memory of the physical computing device.

Abstract: An offloaded virtualization management component of a virtualization host receives an indication from a hypervisor of a portion of main memory of the host for which memory allocation decisions are not to be performed by the hypervisor. The offloaded virtualization management component assigns a subset of the portion to a particular guest virtual machine and provides an indication of the subset to the hypervisor.

Abstract: A peripheral device may implement storage virtualization for non-volatile storage devices connected to the peripheral device. A host system connected to the peripheral device may host one or multiple virtual machines. The peripheral device may implement different virtual interfaces for the virtual machines or the host system that present a storage partition at a non-volatile storage device to the virtual machine or host system for storage. Access requests from the virtual machines or host system are directed to the respective virtual interface at the peripheral device. The peripheral device may perform data encryption or decryption, or may perform throttling of access requests. The peripheral device may generate and send physical access requests to perform the access requests received via the virtual interfaces to the non-volatile storage devices. Completion of the access requests may be indicated to the virtual machines via the virtual interfaces.

Abstract: Techniques for reconfiguring a server to perform various hardware functions are disclosed herein. In one embodiment, a client device sends an instance request to a compute service system for launching an instance. The instance request indicates a resource requirement for the instance. In response to the instance request, the compute service system selects a server from among a plurality of servers in the compute service system based on determining that the server is configurable to at least partially meet the resource requirement. The compute service system then sends a provisioning request to the selected server. The provisioning request includes information for programming a reconfigurable resource of an adapter device in the selected server according to a particular hardware function.

Abstract: Generally described, aspects of the present disclosure relate to a live update process of the virtual machine monitor during the operation of the virtual machine instances. An update to a virtual machine monitor can be a difficult process to execute because of the operation of the virtual machine instances. Generally, in order to update the virtual machine monitor, the physical computing device needs to be rebooted, which interrupts operation of the virtual machine instances. The live update process provides for a method of updating the virtual machine monitor without rebooting the physical computing device.

Abstract: Generally described, aspects of the present disclosure relate to loading an updated virtual machine monitor on the physical computing device during a boot process. The updated virtual machine monitor may be loaded from an update manager external to the virtual machine monitor, such as the offload device or a server connected with the physical computing device over a network. In certain embodiments, the updated virtual machine monitor may be loaded in a tiered process by first loading a startup virtual machine monitor, which automatically updates by loading the updated virtual machine monitor. The startup virtual machine monitor may be a virtual machine monitor with less functionality than the updated machine manager, such as where the startup virtual machine monitor may be a “lite” or simple virtual machine monitor while the updated virtual machine monitor may be a fully functional virtual machine monitor of the most recent update or version.
