Video Transcription
00:04
All right. Welcome to lab number three,
00:07
where we finally get to start working with some virtual machines.
00:14
So we have a host selected.
00:17
We do need to know the host
00:20
root password in case you're not already connected.
00:26
Well, look at the data stores available to us
00:30
for this host.
00:31
We'll also see what kind of guest operating systems we might have available in our
00:36
data store.
00:40
So the data store is used for lots of things. It's it's used for storing ice, Oh, files, for instance,
00:46
which could be used to build any operating system.
00:51
It's also where you store of the V EMS themselves. All the files are contained in one folder
00:57
for each virtual machine,
01:00
and we can also store templates there,
01:03
so we'll explore different options for data stores
01:10
in a later section of the course.
01:18
All right, so now we want to create a virtual machine.
01:21
So we'll go back to her home tab
01:23
if you get lost. And one of the interface is, always remember the home tab so you can
01:29
start again and drill down to wherever it was that you were. When the problem happened,
01:34
we'll go back to our inventory
01:38
inventory is pretty simple
01:42
at this stage.
01:44
You'll notice if you click it some of these tabs in the address bar that you can get other menu choices.
01:55
Once this host is joined to the center, we'll look at some other inventory options that get a little more complex.
02:04
Anyway, I want to do a little bit of cleanup. I made some clones of my servers earlier
02:07
so that I can revert to that clone in case I make a mistake or something gets corrupted, something gets broken.
02:16
This is a great practice if you have the available storage.
02:21
Once you get a server, configure the way you like,
02:23
just make a clone of it.
02:27
Now that clone,
02:29
uh,
02:30
remains a perfect copy that you can store in a different folder. A different directory, different
02:35
storage device.
02:38
So you've got a nice emergency backup plan in case
02:40
the there's some kind of catastrophe.
02:46
But I don't want to look at these clones anymore, someone to remove them from my inventory so I don't have to see them.
02:52
What I can do is right click
02:53
go down to remove from inventory.
02:58
It asks me if I want to remove from the inventory.
03:00
Simple. Yes.
03:02
Uh,
03:04
it does not remove the files.
03:07
It just removes it from the inventory
03:09
that's on this particular host.
03:15
The files that make up those V EMS are still
03:17
existing on the data store, Whichever data store they might be
03:28
okay, So I'm back to my summary tab for the host.
03:31
Let's look at this for a minute.
03:35
We can see a top
03:37
a little noticed that I've got my sshh server configured.
03:43
This is for convenience. When your first building the host
03:46
leaving sshh enabled
03:50
it gives you an easy way to connect to the system.
03:53
For instance, I can just go here and launch party.
03:57
Some of you might be familiar with Putty.
04:00
It's a free
04:01
sshh. Tell Net and are logging Client.
04:05
I've already got some things configured here, so I'll just double click my host.
04:12
That should open the
04:15
the window
04:21
somewhere.
04:24
Here it is
04:26
to make this full screen.
04:28
That's a great future of party, Actually, that allows you to go full screen.
04:36
Now. I logged into my host
04:40
and I can do all kinds of interesting things. I could look at my file systems.
04:45
I can
04:46
run some commands to, uh check the configuration of my network.
04:55
You'll notice some of the commands that you would normally use on a typical UNIX system. Do not work
05:01
on your E S X I host.
05:04
This is due to the fact that there's a
05:08
ah, a limited command sat in order to make the device more secure.
05:12
That means that if somebody was able to brute force
05:15
a root log in to your host, they wouldn't be able to run the commands they're familiar with.
05:20
They would have to do their research ahead of time to know which
05:24
VM where commands they would need to run in order to display these parameters were. Look at those options later. I just wanted to show
05:32
how that would fail.
05:35
Okay, so we're done with the SS H session for now. So exit from that
05:42
back to our host summary tab is very useful.
05:45
It gives you a nice at a glance view of all of your configuration parameters
05:50
the actual hardware, how much memory and see if you you you're using,
05:57
I can tell it a glance that I have three different types of storage attached
06:03
Looking at capacity statistics. How much is free?
06:08
I know which network I'm connected to.
06:12
I can see details about the hardware.
06:15
I've got four cores
06:16
at nearly 2.7 gigahertz, and so on
06:21
tells you which image profile I used to build this
06:25
moving Anne s ex I host is very easy. By the way, if you've never tried it and you've been filing along up to this point, I highly recommend
06:32
pausing the video
06:35
after I'm done explaining.
06:38
It's very easy to download
06:41
the
06:42
trial version of US X I from Vienna, where dot com
06:46
You just register with your email address and some other details,
06:50
and you can build this and
06:54
from the eye. So image, which means that you can run it from VM or player
06:59
so you don't have to spend any money to do this. That's that's the beautiful thing.
07:04
Once you've got it built, then you can explore the other trial options for things like the center or the server appliance and so on.
07:13
And you have a generous 60 day window
07:15
to build an environment,
07:17
test your knowledge, test your skills, do these labs again and again until you until you get all of them right. That's that's really the key.
07:29
And because it's virtual, it makes it very simple, too.
07:32
Build and destroy as you will in order to accomplish your different training goals.
07:42
All right, so I was getting rid of the EMS earlier. This other one here? Yes, that's one. I'm gonna leave that guy behind when we need him for later.
07:50
All right, So your next task is to create a virtual machine
07:57
the lots of different ways to do this.
07:59
Ah, but since we're connected directly to the host the using squares to right, click the host
08:03
and select new virtual machine.
08:07
You'll notice that there are shortcuts next to the menu choice,
08:13
and I always recommend learning the shortcuts. Try to force yourself a little bit if you can.
08:20
Because once you're in the interface,
08:22
it makes a lot more sense to know quick keyboard shortcuts to do what you want. So you're not screwing around with the mouse.
08:31
I think the mouse really slows you down.
08:33
Um, once the interface is open, you hit tab, move around, shift time to go backwards. It's It's pretty easy.
08:41
Anyways, we'll use the menu for this time.
08:43
New virtual machine.
08:52
Okay. For our purposes, we're going to can configure a custom virtual machine.
08:56
You see the options change between typical and custom,
09:03
so we'll call this V M one
09:09
or something that you like better.
09:11
I have three different data stores configured
09:15
so I can pick from these
09:18
local disc is is generally going to be the fastest data store.
09:22
It'll it will give the best performance.
09:26
Local disc could mean a lot of things that could be a single disk drive,
09:28
which is the case with my particular host.
09:33
Or it could be a raid array.
09:35
I could have five discs, 7 12
09:41
that could all be local desk.
09:45
But because it has the shortest distance to travel between the storage media and
09:50
the network, and after
09:52
this is this gives the best performance. There's last late and see. We don't have to deal with the network or anything like that.
09:58
I also have configured
10:00
I scurvy
10:03
and the ice scuzzy storage
10:05
allows me to run scuzzy commands over the network.
10:11
So those of you familiar with scuzzy Dr Know that
10:15
you used to have a wide ribbon cable
10:18
and the commands for
10:20
reading writing data, you know, were sent over. That scuzzy was invented for multi user computer systems so that we could get
10:28
a lot of people accessing the storage simultaneously with decent performance.
10:33
So with ice cosy now, those same commands could be sent over the network
10:37
to a virtual drive.
10:41
Sorry, not a virtual drive, but it of
10:43
a virtual
10:45
that's a virtual disc. In a sense, because it is a partition on a larger storage unit,
10:50
it's using logical volume manager. You can subdivide that storage,
10:56
by the way.
10:58
So the same commander sent over the network that used to be central with wire, and the disc behaves the same.
11:05
And then our third option is NFS,
11:07
which is your typical share drive from a UNIX system. Or if you share a folder from Windows
11:13
that's using on a fast, same thing.
11:20
Okay, in this case, we're gonna stick with local disc for the performance reasons I mentioned.
11:24
You can clearly see all the stats you would want to know about your very storage options
11:33
for this particular configuration. I can only go as high as virtual machine version ache.
11:41
That is the most recent version. If you had legacy equipment that not support,
11:46
um,
11:48
that virtual hardware version you could use version seven, Version four.
11:54
That would be the only reason to downgrade. Maybe you've got an older host
11:58
that can't be upgraded for some reason and that you're stuck.
12:01
So that's why you have these options to use a lower version.
