Abstract: The disclosure provides an approach for eliminating issues associated with the use of an L2 extension and ARP calls after migrating a virtual machine from one host to another host. The approach involves placing nodes within a network within their own subnetworks, each subnetwork having an IP address range of one address. Placing nodes into subnets of one avoids intra-subnet forwarding, eliminating the need for ARP calls and for L2 extensions.

Abstract: Processes for managing computing processes within a plurality of data centers configured to provide a cloud computing environment are described. An exemplary process includes executing a process on a first host of a plurality of hosts. When the process is executing on the first host, a first network identifier associated with the plurality of hosts is not a network identifier of a pool of network identifiers associated with the cloud computing environment and first and second route tables respectively corresponding to first and second data centers of the plurality of data centers associate the first network identifier with the first host. The exemplary process further includes detecting an event associated with the process. In response to detecting the event associated with the process, the first and second route tables are respectively updated to associate the first network identifier with a second host of the plurality of hosts.

Abstract: Methods and devices for providing reserved failover capacity across a plurality of data centers are described herein. An exemplary method includes determining whether a management process is executing at a first data center corresponding to a first physical location. In accordance with a determination that the management process is not executing at the first data center corresponding to the first physical location a host is initiated at a second data center corresponding to a second physical location and the management process is executed on the initiated host at the second data center corresponding to the second physical location.

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.

Abstract: The disclosure provides an approach for dynamically reprogramming network and network infrastructure in response to VM mobility. The approach provides a hypervisor layer that can observe changes in VM-host relationships and reprogram the associated network and network infrastructure to maintain network communication. The hypervisor layer notifies a controller of a data center to migrate an ENI of the migrated VM to the same destination host as the migrated VM, in response to VM migration.

Abstract: Examples maintain consistency of writes for a plurality of VMs during live migration of the plurality from a source host to a destination host. The disclosure intercepts I/O writes to a migrated VM at a destination host and mirrors the I/O writes back to the source host. This “reverse replication” ensures that the CG of the source host is up to date, and that the source host is safe to fail back to if the migration fails.

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: 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: A method for transferring guest physical memory from a source host to a destination host during live migration of a virtual machine (VM) involves (a) transmitting pages of the guest physical memory from the source host to the destination host over a network connection, (b) transferring state information from the source host to the destination host, (c) while performance benefits regarding continued access to the guest physical memory on the source host persist, using the transferred state information to run the VM on the destination host in place of running the VM on the source host, and (d) while the VM is running on the destination host, writing pages of the guest physical memory from the source host to a shared datastore such that the destination host can retrieve the written guest physical pages from the shared datastore.

Abstract: Embodiments support instant forking of virtual machines (VMs) and state customization. Virtual device state and persistent storage of a child VM are defined based on virtual device state and persistent storage of parent VMs. After forking, a state of the child VM is customized based on configuration data. Customizing the state includes configuring one or more identities of the child VM, before bootup completes on the child VM.
