    Abstract: Technologies for enforcing virtual machine network access control include a network computing device that includes a plurality of virtual machines. The network computing device is configured to receive an access request from a virtual function assigned to a requesting virtual machine of the network computing device. The network computing device is additionally configured to determine a first privilege level assigned to the requesting machine and a second privilege level assigned to the destination virtual machine, and determine whether the requesting virtual machine is authorized to access the destination virtual machine based on a comparison of the first and second privilege levels. Upon determining the requesting virtual machine is authorized to access the destination virtual machine, the network computing device is additionally configured to allow the requesting virtual machine access to the destination virtual machine. Other embodiments are described herein.

    Abstract: Disclosed is a source host including a processor. The processor operates a virtual machine (VM) to communicate network traffic over a communication link. The processor also initiates migration of the VM to a destination host. The processor also suspends the VM during migration of the VM to the destination host. The source host also includes a live migration circuit coupled to the processor. The live migration circuit manages a session associated with the communication link while the VM is suspended during migration. The live migration circuit buffers changes to a session state and transfers the buffered session state changes to the destination host for replay after the VM is reactivated on the destination host. The live migration circuit keeps the sessions alive during migration to alleviate connection losses.
