Lab 10 part 1. Making modifications to an existing virtual machine This lesson discusses making modifications to an existing virtual machine. Participants receive step by step instructions in a lab-based class. Participants learn how to:
-
Increase the size of the virtual disk file
-
Adjust the memory allocation
-
Rename a VM
-
Add a raw LUN to a VM
-
Expand a disk provisioned with thin provisioning
It is possible to do all of these functions with the machine powered up so there is no downtime.
Video Transcription
00:04
hello and welcome to lab number 10
00:07
in this lab will be making some modifications to existing virtual machine.
00:13
First thing we'll do is increase the size of the virtual disk file. Then we'll adjust its memory allocation.
00:19
Then we will rename Of'em.
00:23
We will add a raw London
00:26
two of'em,
00:28
and then we will expand disk that was provisioned with thin provisioning.
00:34
Okay, so for our first task,
00:36
we're going to increase the size of the virtual disc.
00:43
So I will go ahead to my
00:46
wind Shevin clone
00:49
that we created in the last lab.
00:52
And I can do actual its power, this guy up.
00:57
We can do this while the machine is powered up.
01:07
Mmm.
01:08
You can also do this activity where the machine is down, but it's more instructive to show it when it's powered up.
01:15
Uh,
01:17
to basically reconfirm that
01:19
a lot of these changes are possible while the machine is up and running,
01:23
so that when you need to make changes like this in your environment
01:26
in the future,
01:27
you'll realize that in some cases you do not have to endure any downtime.
01:34
Yeah,
01:37
Okay, so the machine is powering up.
01:40
We're almost booted
01:46
and This is a window seven V. M. So the process is slightly different If you're,
01:51
um,
01:52
trying to extend a volume on something
01:53
older like a server 2003 year 2008
01:57
you can actually use a utility
02:00
created by Del
02:01
called E X T part,
02:04
which stands for extend partition.
02:08
But with Windows seven and some other more modern server operating systems, like a server 2012
02:15
and so on, you can
02:16
extend the, uh, C drive without using any external tools.
02:23
The tool from Dell is free. It's very easy to find.
02:27
So if you have
02:28
22,003 or 2008
02:30
just do a quick search for
02:32
Del E x t part
02:35
and you should be able to locate that utility.
02:43
Okay, I'm gonna go ahead and log in here.
02:52
All right, So let's have a look. First ad
02:54
our current hard drive size,
03:00
getting a message about my paging file being kind of small, that's fine.
03:05
And we can see that I am almost out of space, so I really do need to increase the size of this drive. 33. Meg is barely any storage
03:15
to have in reserve,
03:16
huh?
03:20
So Our first task
03:21
is to expand the virtual hard disk.
03:23
We can do this
03:25
by going to the VM menu, selecting at its settings.
03:30
You can also do it by right clicking the VM and going to edit settings
03:34
works same way.
03:37
So we'll edit our settings
03:39
and I'll be selecting my hard disk and you can see that the provision size my hard disk is 10 gigabytes.
03:46
I'm using, like 99% of that right now, So I'm gonna go ahead and increase this
03:53
by two gigabytes.
03:53
12 Gig should give me enough storage to continue to use this VM and install updates in the future and so on.
04:03
So ah, very simple operation here. Just change that number
04:08
and click OK,
04:10
now if I examine that hard disk
04:14
from within the operating system itself,
04:19
So I'm going to the disco manager just going to start menu typing, creating format hardest partitions.
04:28
So let's bring this up.
04:35
Now we can see that my partition still tend. Gig. It's not showing,
04:41
and he changes.
04:43
Okay, so
04:45
I see my disk hair,
04:46
but it's still showing only 10 gigabytes, So what I have to do is refresh
04:51
the disk management view,
04:53
and now we can see that the analogue Kate ID two gigabyte portion shows up.
05:00
Sometimes that happens with just the manager.
05:02
Now I need to do is
05:04
right. Click on that volume
05:06
and say, Extend volume
05:13
helps me increase the size of simple and span volumes so I can add space for more time or additional discs.
05:20
In this case, I've got a ah, my default. Just get selected, which is his two gigabyte portion.
05:28
Could also specify the amount by typing in a number or using the buttons,
05:32
so I'll go ahead and click next and finish.
05:35
And now I've got 11.9 gigabyte partition
05:42
refresher this screen as well.
05:46
Now I've got 1.99 gigabytes free.
05:50
Yeah,
05:51
so pretty easy to do
05:54
again. If you're using an older OS, you do need to use
05:58
a different third party utilities such as Dell's extend partition,
06:02
and you can see that I've got that, actually, on the desktop here E x t part.
06:09
Okay, so our next task
06:12
is to increase the amount of memory that this machine is using.
06:19
So if I go to at its settings
06:24
and I select RAM, you'll notice that It's great out. I can't adjust the memory size while the virtual machine is actually up and running.
06:31
So I'm gonna go ahead and cancel that,
06:33
and I will shut the machine down.
06:42
Okay? It's installing some updates.
06:44
Ah, let's go ahead and
06:46
select a different machine. Since that one might be busy for a minute.
06:53
Shell shut this guy down right from this menu.
07:08
Okay,
07:09
Now the machine is
07:11
just about shutdown.
07:15
Okay, There we have it.
07:18
Now go to added settings,
07:23
and I'm gonna increase the disc's size on this machine as well.
07:28
Since I wanted to match the one that I cloned earlier.
07:31
I've got a lot of updates to install, and I want to make sure I have plenty of space for that.
07:36
So I've increased the disc's size. Same way I just did on the other system.
07:42
Then I want to select my memory,
07:44
and I want to give more memory to the machine.
07:48
So right now I have two gigabytes. I'll change that to three gigabytes.
07:55
That way, this machine will have more resource is, and I'll be able to do more with it, so click okay
08:03
and I can boot the machine.
08:11
See how the other one is doing
08:13
all right, that was still installing updates.
08:22
Anyways, while this machine is booting, we could move on to our next task.
08:28
In the case of
08:31
this particular machine called Win Seven Clone, that's pretty descriptive name.
08:35
But I can also rename this,
08:39
so I'm gonna call it Whips
08:43
Rename,
08:45
and I will call it Win seven Clone number two.
08:52
So this renaming
08:54
is really on Lee for inventory purposes,
08:58
and we can prove that
09:01
by going to the actual data store for this virtual machine.
09:05
And you'll see that when you look at the data store
09:09
that the name of the folder and all the configuration files
09:13
has not modified. Once
09:16
the machine has changed,
09:20
so go to my host
09:22
actually could do us a couple differently. Let's let's click the VM.
09:28
We'll go to the summary tab.
09:30
Now I know for sure which storage my machine is living on because it tells me I'll right click the storage, browse the data store
09:46
and this data stores should hold all of the virtual machines, and I so files
09:54
It's taken a moment for to update.
10:05
Okay, there we go.
10:05
So this machine was called wince Win seven clone
10:11
and we can see that it's that it's still here. The folder is still here.
10:15
It hasn't been renamed to Win seven Clone, too,
10:20
and you can see all of the different components that virtual disk file
10:24
the configuration followed. B M X file.
10:26
All these have their original naming.
10:33
So keep this in mind that when you re name of of'em, it's on Lee the inventory view that contains the new name.
10:39
If you want everything to change,
10:43
you either have to change these file
10:45
file names manually,
10:46
which
10:46
could be a little bit tricky if you make a mistake. Not a virtual machine may not boot.
10:54
Um, other options would be to clone the machine,
10:58
and in the process of cloning, you can give it a new name, and then all the files will be renamed correctly.
11:05
Okay, so our next task
11:07
we're gonna go ahead and close the dairy store down,
11:09
and I want to
11:11
at a raw London
11:15
to one of my virtual machines.
11:18
So we'll go ahead and pick the wind seven machine
11:24
and I can right click and go to you at its settings
11:30
and all of my hardware devices. are contained here. We can see I've got three. Gig of Ram.
11:35
I've got a 12 gigabyte hard disk.
11:39
Although I think if I remember right, this one is not had the operating system extended yet, So I have to do that eventually.
11:46
But for right now, what I want to do is add a device
11:50
so quick, the ad button.
11:52
I'm going to be adding a hard disk
12:01
click next.
12:03
And I can use a, uh, create a new virtual disk here,
12:07
or use one that already exists.
12:11
Or in my case, we're going to use a raw device mapping. This means that
12:16
that I've created a lung on my storage area network,
12:20
and I'm going to allow the virtual machine to use it directly.
12:26
Click next.
12:28
So the last Lund that I've got available
12:31
is this one here.
12:31
Channel zero, Target three Lund 4 to 3 gigabyte volume
12:37
so I can go ahead and select it.
12:39
Typically, you want a store,
12:43
the,
12:45
um,
12:46
the files with the virtual machine, as we have here.
12:52
Or you could you could specify a ah different data store if you wished.
12:56
I'm just gonna pick the one that the virtual machines already stored in which is my local desk.
13:03
Go ahead and click next.
13:07
This is another important question you have to deal with.
13:11
Ah, if you do the
13:13
physical compatibility mode now, the OS is accessing the hardware as if it was locally attached. Disc
13:20
that unfortunately means that you cannot use snapshots.
13:26
So if we want to use other functionality for re sizing and volumes and for snapshots, then we need to pick virtual compatibility mode.
13:37
So go ahead and select that
13:41
the, uh,
13:43
the device node that comes up virtual device node. We could leave this at the default setting.
13:50
And if you remember,
13:52
WeII spoken earlier labs about the actual mode.
13:56
If you put your book disk into independent mode
14:01
in persistent independent mode, that means that
14:03
all the changes are written to the disc the way you would normally expect.
14:07
Or we can select non persistent,
14:09
where changes are not maintained after a reboot.
14:13
We're just gonna de select that to use the
14:16
the deep default mode here. We're not going to use the independent mode.
14:20
We get our summer screen
14:22
showing us our target lung and virtual device. No, that's going to be mapped to this V M
14:28
and we click finish.
14:31
Now we can see that the new hard disk is being added. We've got a map raw London
14:37
being attached to this device.
14:41
So go ahead and click. Okay,
14:48
Now, if I
14:48
keep this virtual machine selected in the inventory
14:52
and go to my storage views,
15:00
I can see that
15:01
if I want to see all my virtual machine files,
15:05
it's telling me
15:07
within this directory on my
15:09
data store,
15:11
all the files that comprise this PM
15:16
tells you what the file type is, how large it is.
15:22
I can click the update link
15:26
so that it can update anything that's changed, and we can see that I've got a bunch of new files here,
15:33
and what we're looking for is
15:37
the V M D. K file
15:41
for the machine that was for the rather for the disk that was just created.
15:46
We can see. There it is. It's a three gigabyte file.
15:48
I've got a new virtual
15:50
machine rub
15:52
virtual disk file
15:54
showing me that extra storage that's now available
15:58
to their system.
16:00
So everything that's win seven underscore one
16:03
is that second disk. The original disk
16:07
is just windows seven. We consort this by name and make that a little bit easier
16:12
to see the changes.
16:14
So the underscore one
16:15
items are are those new items from adding adding the disc?
