3.3 Virtual Machine, Network, Hard Disk Creation Part 3

all right, so
external, internal and private networks now these are specific to hyper V.
there are three possible Moz as well. As you might have guessed from the title at the top. The 1st 1 is private, so
this allows communication between virtual machines on its host.
It's purely logical. It doesn't use any physical adapter in any way. When I say logical, what I mean is, it exists in bits
s so there's no actual switch box. There's no connection to the outside world. It's just a virtual, totally virtual environment.
It only allows you to talk between virtual machines on the actual host
on nothing else. Now, this is really important to keep in mind
when I say nothing else. No, even the host machine can talk to these viens when they're on a private network.
So if you want to be able to do stuff from your host machine, maybe you're administering it from a physical machine you're on
and you're using a private network,
you won't be able to only the V. EMS can talk to each other on a private network,
so keep that in mind. It's it's totally benign to the rest of anything.
So, as I said, even the management operating system won't be able to do anything. So that's that's private network. It's private in the sense that it's not related to private I. P. Addressing If you ever seen a peeper, if anyone's done that, it's automatic private I p addressing.
Basically, it's not related to that. So don't confuse a private network for anything to do with private eye peas. You can mentally think of this
as a switch that has no ability to uplink to other switches. You have no capability whatsoever of plugging this switch into any other switch. It's end of story. It's a that's a CE faras. This network will go,
so that's private. Then we get to internal so internal, very similar to the private switch. With one exception,
the management operating system can have a virtual adapter on this type of switch, which means now you can speak to the network that you've built using your management operating system still isolated.
But as I said, it allows the management operating system to directly communicate with any of'em that also has
I also have virtual adaptors on the same internal switch,
so like the private switch. However, the internal switch does not have a relation to a physical doctor. It's purely logical,
and therefore it cannot up linked to any other switch. So private and internal,
you're not gonna Lincoln to any other switch. So just keep that in mind when you're doing stuff like this.
All right. Now here's the one that many people use unless you're trying to segregate network
external switches. So don't confuse this switch type with public I. P. Addressing schemes
or even let its name suggests that it needs to be connected to an Internet facing system it doesn't have to. External just means that
it needs to be connected to a physical doctor.
That's literally all it means.
It doesn't have to be Internet facing. It just means that you're allowing it to go to other switches, networks and so on.
That's all. If that's what it means by extending, it means external to the virtual environment, so the virtual environment could go to another virtual environment. It could go to a physical environment. It could go out to the Internet. Whatever you decide to give it
is what is the external section off this switch
you can use the same private I p addressing range for the adaptors on an external switch. Virtual switch that you're using on the physical network that it's attached to external in this usage means that it can connect systems that are external to the hyper V host.
That's the key thing to remember with external networks
eso just to bring up those on the little play, but means that I am actually going to show you this so that you guys can see what it looks like. We're gonna go through this in a lot more detail when we build the network in a short while. Actually, hopefully in about 15 20 minutes or so, but
I'm gonna give you a quick rundown of these three types of networks now.
So let me open up my hyper V environment.
There's my manager.
So again, those of you be following with me. You know that my my host is called deadpool. If those of you haven't come on
a little trip with me a little training session I name or mike machines and devices. After Marvel characters on the huge Marvel fan on, I got into quite a bit of trouble with my producer by saying I didn't like Batman, so
please don't hurt me, man. Thank you.
So what we're gonna be doing here? I'm sure I'll get a message in the second popping up. What we're doing here is I'm just gonna show you very quickly wth e three different types of network. So you got your manager, which is the software? Deadpool is the server that I'm running at the moment on. Over here on the right hand side,
you'll see that there's virtual switch manager. Now, what this does is it allows you to create these voters switches, which we're gonna be using very shortly.
And here you can see there's the new virtual switch virtual network switch that you would pick,
and then you would pick from here the three. And if you don't actually remember, when you kind of forget what we're what we discussed about what each network does, there's a handy little description just underneath that explains what each one can and can't do effectively. So you would pick one and then create virtual switch. It pops on the left hand side.
You can have as many virtual switches as you like
on your on your manager. Here, you can create a virtual switch for any kind of connection,
and it's really nice for being ableto isolate. Data moving between the EMS or between the hyper V hosts and the rest of the network
allows you to very quickly pick up what's going on around the network and allows you to traffic shape effectively.
Eso here you'll see when you do pick it. That's not to say that just because you picked it, it will not try to change. You can change the options here. I won't go into too much detail straightaway. We are gonna be going over these when we actually build the network as well. If you do click the little plus here as well. In the left hand side, you got extensions
after you actually create the switch, and he either apply are okay. This is where you'll find extensions that go into it. Let me see if I can show you the ones he go, so that's that's a screen of a default switch that we've discussed this in our previous one. The default switch comes as part of the hyper V client or Windows 10 and it allows you to very quickly get online. The default switch by default,
we don't know,
gives you an external switch to attach to,
but allows you to activate. You can have a filter extension, a forward extension of monitoring extension as Mork come out or you decide to install further drivers for this. You can also turn these on.
You were able to put them in the system here that allows you to actually use them and turn them on. And you can do all kinds of stuff with them but filtering data that's moving through the network or seeing what's going on that kind of stuff.
So that's basically a very quick rundown on a show off. What to expect from these? We will go into a lot more detail with this in just a few minutes, actually. So with me on that one, hold that for
All right, so
