    Abstract: A computer-implemented method, system and computer program product for securing access to a virtual machine via a service processor. A broadcasted request from a computing device of a user to establish a virtual session with the virtual machine through a service processor is received. Such a broadcasted request includes an identifier of the virtual machine as well as a key. A secure connection between the service processor and the computing device of the user is established in response to the broadcasted identifier of the virtual machine matching the identifier of the virtual machine in the service processor table. After establishing the secure connection between the service processor and the computing device of the user, a secure connection between the service processor and the virtual machine is established in response to the broadcasted key matching the key associated with the identifier of the virtual machine in the service processor table.

    Abstract: Methods and systems for migrating a virtual machine instance between devices include one or more migration risk rules, each migration risk rule relating to a validation set having one or more validation substasks. A processor is configured to score a received migration request against one or more of the migration risk rules to generate one or more scores for the migration request, to compare each score to a respective threshold to determine if a level of risk according to the respective rule merits performing validation for the validation set, to validate the migration request by only those validation sets that correspond to the scores that exceed the respective threshold, and to trigger migration of a virtual machine to a target device in accordance with the migration request if none of the validation sets fail to validate the migration request.

    Abstract: The present disclosure includes a method for migration of a first virtual function of a first device located on a PCI bus and accessible by a device driver using a virtual address. A second virtual function is created on a second device. A base address is determined for the second virtual function as a function of a logical location of the second device within the PCI structure. An offset is determined for the second virtual function as a function of the base address and the virtual address. The device driver is notified that the first virtual function is on hold. The offset is stored in a translation table. The device driver is notified that the hold has been lifted. Accesses to the virtual address and by the device driver to memory of the second virtual function are routed based upon the offset in the translation table.

    Abstract translation: 本公开包括用于迁移位于PCI总线上并可由设备驱动程序使用虚拟地址访问的第一设备的第一虚拟功能的方法。 在第二设备上创建第二个虚拟功能。 根据第二设备在PCI结构内的逻辑位置的函数确定第二虚拟功能的基地址。 根据基地址和虚拟地址确定第二个虚拟函数的偏移量。 通知设备驱动程序第一个虚拟功能处于保持状态。 偏移量存储在转换表中。 通知设备驱动程序已暂停保持。 基于转换表中的偏移，对虚拟地址和设备驱动程序访问第二虚拟功能的存储器进行路由。
