Seamless Network Characteristics For Hardware Isolated Virtualized Environments

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.
