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： Methods, system and machine-readable medium are described to handle a device related operation in a virtualization environment. In some embodiment, a kernel component of a virtual machine monitor may determine that a device related operation happens in a virtual machine through a operation transition from the virtual machine to the kernel component; and may determine whether the device related operation can be handled by a first virtual hardware device installed inside of the kernel component of the virtual machine monitor. In other embodiment, the kernel components may initiate an interrupt by the first virtual hardware device; and inject the interrupt from the first virtual hardware device to the virtual machine through another operation transition from the kernel component to the virtual machine.
