As I mentioned,
this part of exam AZ‑800 is all about knowing various and sundry features,
or VM management topics in Hyper‑V.
We'll start by considering Hyper‑V integration services.
Now these are Windows services that run on your Hyper‑V host that allow
bidirectional communication between your VMs and the host itself.
I think that Hyper‑V integration services is very analogous to the Azure
Virtual Machine Agent that we have in our Azure subscriptions,
particularly the Hyper‑V heartbeat service.
Heartbeat messages happen between the guest VMs and the host
server to let the server know that the virtual machine is
still available and reachable.
Let's now take a bit more detailed look at each integration service.
We've got the Guest Shutdown Service,
and that simply allows the Hyper‑V host to shut down the VMs on it.
Time Synchronization ensures that your VMs time and
time zone matches that of the host.
Data Exchange supports bidirectional, well, data exchange.
Volume Shadow Copy Requestor is particularly important for our discussion
later in this module on virtual machine checkpoints.
Volume Shadow Copy Service in Windows, which you probably already know,
allows you to back up open files, and specifically,
the Volume Shadow Copy Requestor integration service
allows you to back up a running virtual machine using
first or third‑party backup software.
Then we have the Guest Service Interface.
This allows, again, resizing.
It's just a more comfortable experience,
session resizing in the VMConnect application.
And then we discussed PowerShell Direct in the previous module.
This is a capability that enables us to send PowerShell from the Hyper‑V host into VMs on that host without using PowerShell remoting.
