Because your VMs are using the Adapter #3 external vSwitch, that internal Vswitch only has the hypervisor connected to it. Your 2nd virtual switch is the Internal one. One is external, and hopefully this is where your VMs are connected and you are allowing the hypervisor to use this NIC as well. So, all of that to say, it appears you have a couple of virtual switches. This physical NIC is still used by the hypervisor (if the checkbox that allows the hosting OS to use that connection is enabled), but it also allows the VMs hosted on the hypervisor to communicate with network devices beyond the hypervisor itself when that port is connected to a physical switch, for example. In other words, there's no physical port to connect a physical Cat cable to in order to connect the hypervisor to a physical switch and beyond.Įxternal virtual switches allow the same level of inter-device connectivity between VMs and the hypervisor as internal switches do, but in this kind of virtual switch, one of the hypervisor's physical NICs is bound to a virtual switch. However, this NIC on the hypervisor is strictly virtual and as such cannot be connected to other physical network devices in your network. In this type of virtual switch, the hypervisor shows a new virtual NIC that can be assigned an address by a VM DC running DHCP, for example. Internal virtual switches allow the same level of inter-device communication between VMs on the hypervisor but in this kind of virtual switch, the hypervisor is also included. Using this kind of virtual switch is pretty much just like running a lab environment inside your hypervisor. They cannot reach the hypervisor, another hypervisor, VMs on another hypervisor, or any network devices outside of the virtualization environment hosted by the hypervisor those VMs are on. Private virtual switches only allow the VMs hosted on a hypervisor to communicate among themselves. The easiest way I've found to explain these is by looking at it from a scope point of view. The switch type doesn't refer to IP but rather whether the virtual switch is one of three kinds, internal, external, or private. VEthernet (Broadcom NetXtreme Gigabit Ethernet - Virtual Switch) #1, it says I can't use the assigned gateway for both.
Is that normal? Since the host is in the same subnet as the VMs, I assumed there would just be one IP for the machine? When I try to assign a static IP to the currently self-assigned So it looks like I have an internal IP and an External IP on the host.
