摘要： Generally, this disclosure describes systems (and methods) for moderating interrupts in a virtualization environment. An overflow interrupt interval is defined. The overflow interrupt interval is used for triggering activation of an inactive guest so that the guest may respond to a critical event. The guest, including a network application, may be active for a first time interval and inactive for a second time interval. A latency interrupt interval may be defined. The latency interrupt interval is configured for interrupt moderation when the network application associated with a packet flow is active, i.e., when the guest including the network application is active on a processor. Of course, many alternatives, variations, and modifications are possible without departing from this embodiment.

摘要： A virtualization based system comprises a host and a plurality of virtual machines that may each comprises a guest memory. A virtual machine monitor has access to underlying platform hardware in the system and may control physical resources in the platform. The platform hardware comprises a processor and a memory coupled to the processor. Further, the VMM may manage guest software including guest operating systems running on the virtual machines. A binary translation logic may replace guest memory writing instructions corresponding to a hot spot in guest application with translated codes to generate a mirrored content for the guest memory. The binary translation logic may combine one or more of the guest memory writing instructions in a region and keep the region atomic. The processor may execute the translated codes in an atomic region together to write a content in the guest memory and a mirrored content in a mirroring memory. The VMM may allocate a memory region in the host memory for the mirroring memory. The guest memory comprises one or more guest memory pages and the mirroring memory may comprise one or more mirroring memory pages. The VMM may add an offset to a virtual address of a guest memory page to obtain a virtual address of a mirroring memory page. The VMM may manage or emulate a guest page table comprising a mapping between virtual address to guest physical addresses for the guest memory. The VMM may synchronize a shadow page table with the mapping in the guest page table. The shadow page table comprises a mapping of virtual addresses to host physical addresses for the guest memory and a mapping of virtual addresses to host physical addresses for the mirroring page. Upon a memory failure in the guest memory page, the VMM may restore the content of the corrupted guest memory page from the mirroring memory page.

摘要： A machine-accessible medium may contain program instructions that, when executed by a processor, may cause the processor to perform at least one operation including searching a virtual hash page table (VHPT) using a region identifier and a virtual page number of a virtual address, and a default page size corresponding to the region identifier to locate a virtual address translation in the VHPT. The operation performed may further include searching the VHPT using the region identifier, the virtual page number, and at least one utilized page size to locate a virtual address translation in the VHPT if a virtual address translation is not located during the search of the VHPT using the region identifier, virtual page number, and default page size. The operation performed may also include inserting the located virtual address translation into a translation cache once a virtual address translation is located.

摘要： An apparatus, system, method, and machine-readable medium are disclosed. In one embodiment the apparatus is a network interface controller that includes one virtual function owned by a virtual machine present in the computer system. The controller includes a simple filtering agent that is associated with the first virtual function. The agent enforces simple filter rules for received network packets. The simple filter rules are capable of blocking the network packets from reaching the virtual machine. The apparatus also includes another virtual function that is owned by a virtual machine monitor present in the computer system. The controller also includes a side bounce filtering agent to forward the first network packet to the second virtual function if the first packet is blocked by the at least one of the one or more simple filter rules.

摘要： A processing system executes an emulation patch for a guest virtual machine (VM) of the processing system. In one embodiment, the emulation patch includes data to facilitate identification of a routine to emulate a guest instruction. After executing the emulation patch for the guest VM, the processing system may use the data to find an emulation routine for emulating the guest instruction. The processing system may transfer control from the guest VM to a virtual machine monitor (VMM) in response to execution of the emulation patch, without saving a trap frame. The VMM may then find and execute the emulation routine for the guest instruction without decoding the guest instruction. A break instruction with an immediate value, for example, may be used for the emulation patch. The immediate value may be used for finding the emulation routine. Other embodiments are described and claimed.
