Abstract: Embodiments of the invention relate to receiving, by a first processor comprising a processing device, an indication that a migration of a virtual machine from the first processor to a second processor is to occur. The first processor transmits user datagram protocol (UDP) packets intended for the virtual machine to the second processor based on the indication. A signal is transmitted to the virtual machine to enter an offline state, wherein the offline states comprises a transfer of at least one of a central processing unit (CPU) state and a memory state, and wherein the virtual machine is configured to halt a processing of the UDP packets in response to receiving the signal. The virtual machine is reactivated once the migration of the virtual machine from the first processor to the second processor is complete. The virtual machine is instructed to resume the processing of the UDP packets.

Abstract: A method for determining allocation of virtual machines includes: at least one of generating and accessing a list of virtual machines (VMs) configured to run on a network, each VM having at least one network resource requirement, each VM in the list associated with a size of the at least one network resource requirement; selecting at least one equivalence set of VMs having a resource requirement size that is at least substantially identical; generating a plurality of meta-combinations from the at least one equivalence set of VMs, each meta-combination representing all possible combinations of a selected number of individual VMs from the equivalence set; determining a maximum resource capacity of a node in the network; and providing a meta-combination assignment to the node, the meta-combination assignment including a group of meta-combinations having a cumulative resource requirement size value that is less than or equal to the maximum resource capacity.

Abstract: Embodiments of the invention relate to performing a scan of a memory region associated with a virtual machine. The scan is performed by a hardware mechanism in response to a call. A data structure that includes information about substrings identified during the scan and a number of replications for each substring is constructed by the hardware mechanism. The data structure is stored by the hardware mechanism at a location determined by the call.

Abstract: Embodiments relate to migrating a virtual machine (VM) between work groups. A first machine in a first work group generates a migration request that identifies one or more contiguous memory regions used by the VM for operation. The first machine transmits the migration request to a plurality of work groups. The first machine receives a score from each of the plurality of work groups indicating a number of contiguous memory regions identified in the migration request that are available at the respective work group. A second work group in the plurality of work groups is identified as a destination for the VM based on the scores and a distance of the second work group from the first machine. A migration of the VM from the first machine to a second machine in the second work group is caused based on the identification of the second work group as the destination.

Abstract: Embodiments of the invention relate to scanning, by a first processor in a work group, a memory associated with the first processor for data. The first processor updates a first data structure to include at least a portion of the data based on the scanning. The first processor transmits a representation of the first data structure to one or more peer processors of the first processor included in the work group using a dedicated link. The first processor receives a representation of a second data structure associated with at least one of the one or more peer processors of the first processor. The first processor updates the first data structure based on the received representation of the second data structure.
