1
00:00:01,340 --> 00:00:02,090
As I mentioned,

2
00:00:02,090 --> 00:00:07,340
this part of exam AZ‑800 is all about knowing various and sundry features,

3
00:00:07,340 --> 00:00:10,000
or VM management topics in Hyper‑V.

4
00:00:10,000 --> 00:00:14,270
We'll start by considering Hyper‑V integration services.

5
00:00:14,270 --> 00:00:18,640
Now these are Windows services that run on your Hyper‑V host that allow

6
00:00:18,640 --> 00:00:23,230
bidirectional communication between your VMs and the host itself.

7
00:00:23,230 --> 00:00:27,920
I think that Hyper‑V integration services is very analogous to the Azure

8
00:00:27,920 --> 00:00:31,500
Virtual Machine Agent that we have in our Azure subscriptions,

9
00:00:31,500 --> 00:00:34,100
particularly the Hyper‑V heartbeat service.

10
00:00:34,100 --> 00:00:39,190
Heartbeat messages happen between the guest VMs and the host

11
00:00:39,190 --> 00:00:42,340
server to let the server know that the virtual machine is

12
00:00:42,340 --> 00:00:44,410
still available and reachable.

13
00:00:44,410 --> 00:00:48,540
Let's now take a bit more detailed look at each integration service.

14
00:00:48,540 --> 00:00:50,480
We've got the Guest Shutdown Service,

15
00:00:50,480 --> 00:00:55,140
and that simply allows the Hyper‑V host to shut down the VMs on it.

16
00:00:55,140 --> 00:00:58,350
Time Synchronization ensures that your VMs time and

17
00:00:58,350 --> 00:01:00,470
time zone matches that of the host.

18
00:01:00,470 --> 00:01:04,300
Data Exchange supports bidirectional, well, data exchange.

19
00:01:04,300 --> 00:01:08,930
Volume Shadow Copy Requestor is particularly important for our discussion

20
00:01:08,930 --> 00:01:12,080
later in this module on virtual machine checkpoints.

21
00:01:12,080 --> 00:01:16,240
Volume Shadow Copy Service in Windows, which you probably already know,

22
00:01:16,240 --> 00:01:19,530
allows you to back up open files, and specifically,

23
00:01:19,530 --> 00:01:22,730
the Volume Shadow Copy Requestor integration service

24
00:01:22,730 --> 00:01:26,120
allows you to back up a running virtual machine using

25
00:01:26,120 --> 00:01:28,590
first or third‑party backup software.

26
00:01:28,590 --> 00:01:31,040
Then we have the Guest Service Interface.

27
00:01:31,040 --> 00:01:32,850
This allows, again, resizing.

28
00:01:32,850 --> 00:01:35,270
It's just a more comfortable experience,

29
00:01:35,270 --> 00:01:37,770
session resizing in the VMConnect application.

30
00:01:37,770 --> 00:01:41,470
And then we discussed PowerShell Direct in the previous module.

31
00:01:41,470 --> 00:01:52,000
This is a capability that enables us to send PowerShell from the Hyper‑V host into VMs on that host without using PowerShell remoting.
