3.1 Creating Virtual Machines

00:00

Hi,

00:01

You are watching Model three managing virtual machines.

00:06

Lesson one. Creating fertile machines.

00:09

By the end of this video, you learn how to create a virtual machine

00:14

and how to allocate resources to it.

00:17

No,

00:18

we've talked a lot about Virgin jeans. Let's now create one.

00:23

But just before we do that, let me remind you that virtual machine has virtual resource is that it gets from the hyper visor.

00:31

But it is the job off the administrator to configure how much virtual resource is of'em will get.

00:39

The most important resources are CPU, memory disk and network interface cards.

00:45

But allocating these resources should not be an exercise off trial and error.

00:51

He should always consider the requirements off the underlying operating system off the V M

00:57

and the applications that will be running on it.

01:00

If you're operating system needs at least two gigabytes of RAM and the application running when it needs at least two gigabytes of available memory at all times, then you better take that into consideration.

01:15

In this case, you can configure a memory reservation, which is the minimum guaranteed to the virtual machine.

01:23

Two gigabytes off reserved memory, for example, means that these two, your bites are going to be malakal ized. By that, Veum

01:32

and no other Veum will have access to it.

01:36

It also means that if you ***, I cannot provide those two gigabytes of reserve memory. The VM won't even power on,

01:45

and the same goes for storage.

01:47

Now let's create a virtual machine.

01:49

We'll create a virtual machine with the Lenox operating system. I already downloaded the Esso image off one to server.

01:59

Let's connect to the center

02:14

now, right, click the Yes X. I host and choose

02:17

new virtual machine

02:21

and the next window. It gives you many options.

02:23

You can create a new virtual machine from scratch by selecting create a new virginal

02:30

from a template by selecting deploy from template.

02:35

We will talk about this in the next video,

02:38

you create of'em by cloning another virtual machine,

02:42

and you can also create a template from an existing veteran machine. We will also talk about this in the next video,

02:51

and you can create a template by cloning another template,

02:54

and finally, you can create a V M by converting an existing template.

03:00

Now, in our case, select the first option and click next

03:06

name your Veum.

03:07

I'm gonna name it Webb,

03:09

as it will be running a Web server.

03:14

Next, select the U. S X I host on which this Veum will be created,

03:23

and then select the data store where the VM files will be stored.

03:29

And for the compatibility, select the newest yes, Excite version. If you want to of'em to have access to the latest drivers and features,

03:39

they are identified by a hardware version

03:44

in the case, off years excites 67. Hardware version is 14

03:49

but be careful. This will make your virtual machine incompatible with earlier versions of us. Excited

03:58

now for the guest operating system family Select Lennox

04:01

and for the guest OS version, select a bun to 64 bit.

04:08

This stuff is actually important because your *** I will use the information you provide here to select the adequate image off family tools to install on your fiend later on.

04:18

Now, for the resource allocation, you can see that the wizard already picked default values for your Vian.

04:27

These are the minimum requirements to run the operating system you selected in the previous window.

04:33

If you click on the little arrow next to a given resource. It will display advanced options like setting reservations. For example.

04:43

For the disc, choose thin provisions to allocate disk space dynamically without reservations, which means that your VM will only use that much space as it needs at a given moment.

04:57

Choose thick if you want to reserve the whole 16 gigabytes of disk space, even if you're VM consumes dressed a fraction of it

05:06

in the CD DVD drive we will mount to the I S O image Off are a bun to operating system, but first we need to get that IRS. So image in the data store off the SX I host

05:19

for now, review your settings and hit finish.

05:23

It should take a second or two to create Vienna.

05:27

Now let's upload the operating system. I Esso image to our data store.

05:31

Navigates. Tow the data store.

05:34

You can see here that I already created the folder named Ay, esos.

05:40

Click on it and Jews upload fire.

05:44

Selected the IRS. So image you want

05:47

and it will take a while. Depending on the speed off network.

05:51

I'll speed up the video,

05:55

and there it is.

05:57

Now go back to the hosts and clusters and right click your newly created viene

06:01

and go to edit settings

06:05

under CD DVD, Dr Chu's Data Store s O

06:11

Navigate to where the Esso image is on selected.

06:17

And don't forget to check the Connect box to the right of the CD DVD on, then click. Okay,

06:25

now it's time to power on TV in and start the installation off a bun to server. I will speed up the video and see you after it's done,

06:44

and we're done normally. What we do next is installed them where tools, which is he set off enhanced driver's that will improve the performance off of'em in every aspect.

06:57

But the latest version off onto comes with via metals preinstalled, which is really cool.

07:03

That's how you create a V M from scratch.

07:06

In the next video, we'll see how to create clones and templates off a virtual machine.
