- In this video, I will show you how to use
the graphical interface virt manager to
learn a virtual machine.
This is demo only. For your convenience,
here are the steps that I'm going to perform.
OK, first step is a couple of system checks.
First and foremost, we need the proc CPU info to return VMX.
If you don't see VMX, go to your bios, go to
your virtualization settings,
look for hypervisor extensions or something like that.
And without VMX, you can't install the virtual machine.
Simple like that.
Good. Let's also do a free minus M
to verify the availability of memory.
Eight gigs in total. That's good.
And DF minus eight to verify the availability of storage
I have 34 gigabytes in my root partition.
That's good, as well.
So, I can install the virtualization software
using DNF groups. Install virtualization host.
Alright, now that the core packages are installed
we also need to install the virt manager utility.
That's not a part of the virtualization host,
so it requires a separate install.
There we go. So now that we have vert manager,
let's create an ISO of the insulation disk.
That's a limitation in the vert manager.
For some reason, it can't address the installation
disk directly, so I'm creating an ISO.
Let's not forget the BS is one M
or otherwise you need to wait forever.
Oops, no media found.
Let me connect the installation disk to the virtual machine.
So now I can run my clone operation on the disk.
And once it's ready, we can get started
with the installation.
So the disk is copied. There is one more requirement
and that is system CTL enable Minus minus.
Now lip virt D.
The lip vert D is a generic interface.
It allows these management utilities to communicate
to the virtualization layer.
And now it's time to finally start the virt manager utility.
There we go.
So in the virt manager utility,
you need to click on the icon
in the upper left corner, create new virtual machine.
So local installation is what we need to install
from an ISO image.
And the ISO image, I'm getting access to it
through the browser.
Browse local is what I need.
And then filesystem root where we can find the
rhel9 ISO. As you can see, it has detected
the operating system correctly
so we can forward and specify the next step.
Now, in the next step, choose memory and CPU settings
one and a half gig of memory that is OK, and CPUs, well,
we can use a two-CPU course.
This is the virtual hardware that you are defining
for your virtual machine.
Then, we have 20 gigabytes for the root.
I think that's a little bit much. Let's make 10
because you can see it's indicating we only
have 23 gigabytes available.
And then it specifies name, name sent, rest stream.
That's OK and everything else is OK. Now, let's click finish
and that will start with virtual machine installation.
