What I understand is they do not offer full Thunderbolt bandwidth and they are also rather expensive at 150-250. A bridged network shares a real Ethernet device with virtual machines (VMs). SR-IOV or "Single Root IO Virtualization" is a very interesting feature that can provide virtual machines shared access to physical network cards installed in the hypervisor. If settings are wrong, any guest server that has a Private IP Address will have trouble reaching the internet.
