Abstract: Embodiments described herein relate to providing hardware isolated virtualized environments (HIVEs) with network information. The HIVEs are managed by a hypervisor that virtualizes access to one or more physical network interface cards (NICs) of the host. Each HIVE has a virtual NIC backed by the physical NIC. Network traffic of the HIVEs flows through the physical NIC to a physical network. Traits of the physical NIC may be projected to the virtual NICs. For example, a media-type property of the virtual NICs (exposed to guest software in the HIVEs) may be set to mirror the media type of the physical NIC. A private subnet connects the virtual NICs with the physical NICs, possibly through a network address translation (NAT) component and virtual NICs of the host.

Abstract: Embodiments relate to hypervisors that provide hardware isolated virtualization environments (HIVEs) such as containers and virtual machines (VMs). A first HIVE includes a first virtual network interface card (NIC) and a second HIVE includes a second virtual NIC. Both virtual NICs are backed by the same physical NIC. The physical NIC has an Internet Protocol (IP) address. The virtual NICs are assigned the same IP address as the physical NIC. A networking stack of the hypervisor receives inbound packets addressed to the IP address. The networking stack steers the inbound packets to the virtual NICs according to tuples of the inbound packets. Packets emitted by the virtual NICs comprise the IP address, pass through the network stack, and are transmitted by the physical NIC with headers comprising the IP address.
