Abstract: Techniques for handling inheritance of disk state when forking virtual machines (VMs) are provided. In one embodiment, a computer system can receive a request to fork a child VM from a parent VM. In response, the computer system can take a disk snapshot of the parent VM, where the disk snapshot results in a child disk for the child VM, where the child disk is a delta disk that points to a parent disk of the parent VM, and where the parent disk serves as the parent VM's current running point. The computer system can then determine whether the parent disk is a delta disk. If so, the computer system can copy the content of the parent disk to the child disk, traverse a disk hierarchy associated with the parent disk to identify a base disk above the parent disk in the hierarchy, and cause the child disk to point directly to the base disk.

Abstract: When a request is made to retrieve a guest physical page from memory and a page fault occurs, a guest virtual page address that corresponds to the guest physical page is identified along with addresses for guest virtual pages that are near the guest virtual page in the virtual address space. Each identified guest virtual page address is translated into a corresponding guest physical page address and the corresponding guest physical pages are loaded into memory.

Abstract: A plurality of virtual machines (VMs) is migrated from a source group to a destination group in such as way as to achieve consistency and either availability or group preservation. Execution of VMs in the source group is selectively delayed during state migration so that memory transfer of all the VMs in the group will converge roughly at the same time. After VM state transfer to the destination group, execution switch-over is coordinated using different handshake and acknowledgement messages, passed either through a “leader” VM in each group, or directly between source-destination VM pairs.

Abstract: Memory pages that are allocated to a memory consumer and continue to be accessed by the memory consumer are included in a free list, so that they may be immediately allocated to another memory consumer as needed during the course of normal operation without preserving the original contents of the memory page. When a memory page in the free list is accessed to perform a read, a generation number associated with the memory page is compared with a stored copy. If the two match, the read is performed on the memory page. If the two do not match, the read is not performed on the memory page.

Abstract translation: 多个虚拟机（VM）以这样的方式从源组迁移到目的地组，以便实现一致性以及可用性或组保存。 源组中的VM的执行在状态迁移期间被选择性地延迟，使得组中的所有VM的存储器传输将大致同时收敛。 在VM状态转移到目标组之后，使用不同的握手和确认消息来协调执行切换，通过每个组中的“leader”VM，或直接在源 - 目标VM对之间传递。

Abstract: Embodiments include an infrastructure shared among cloud services that supports fast provisioning of virtual machines (VMs). A set of powered-on parent VM templates and a set of powered-off child VMs are maintained by the infrastructure in a hierarchy. The child VMs are instantiated from the parent VM templates, and pre-registered to a cloud operating system in some embodiments. In response to requests from the cloud services for the child VMs, where the requests specify child VM configurations, child VMs from the set of powered-off child VMs are selected and customized based on the child VM configurations, and then deployed for use by the cloud services. In some embodiments, the fast provisioning of VMs is supported by forking operations in the infrastructure.
