In addition to confguring the virtual hardware for a new virtual machine, you might also
need to confgure some of its management settings As with virtual hardware, you can do this
either by opening the virtual machine’s settings in Hyper-V Manager as shown in Figure 7-12
or by using Windows PowerShell
The management settings you can confgure for a virtual machine are as follows:
■ Name If you want to, you can change the name of the virtual machine as displayed in
Hyper-V Manager and used with Windows PowerShell cmdlets Changing the name of
the virtual machine does not change the names of the virtual machine’s confguration
fles and virtual hard disk fles, however.
■ Integration Services By default, all Integration Services are offered to the virtual
machine However, if you need to, you can disable some or all of these services—for
example if the guest operating system doesn’t support some of them
■ Snapshot fles location By default, snapshot fles are stored in subfolders of the
default location where virtual machine confguration fles are stored. If you frequently
perform snapshots and are running out of storage space on the host storage device,
you might want to change the snapshot fles location to a different storage device.
■ Smart Paging This new feature of Windows Server 2012 Hyper-V allows a virtual
machine that is being restarted to temporarily use disk resources on the host as a
source for any additional memory needed to successfully restart the virtual machine
Then, once the virtual machine has been restarted and its memory requirements have
lessened, Smart Paging releases the previously used disk resources because of the
performance hit that such use can create Smart Paging is used only when a virtual
machine is restarted and there is no free physical memory on the host and no memory
can be reclaimed from other running virtual machines Smart Paging is not used if you
simply try and start a virtual machine that’s in a stopped state, or if a virtual machine is
failing over in a cluster
■ Automatic start action This setting allows you to specify what the virtual machine
should do when the host machine boots up The options you can choose from are to
automatically start the virtual machine if it was running when the VMM service on the
host stopped (the default), to always start the virtual machine automatically, or to do
nothing You can also specify a startup delay in seconds to reduce resource content
between different virtual machines starting up on the host
■ Automatic stop action This setting allows you to specify what the virtual machine
should do when the host machine shuts down The options you can choose from are to
save the virtual machine state (the default), turn off the virtual machine, or shut down
the guest operating system
You can also use Set-VM cmdlet of Windows PowerShell to confgure the preceding virtual
machine management settings For example, to change the name of virtual machine SRV-A
n HOST4 to SQL Workload, you would use this command:
et-VM -Name SRV-A -NewVMName "SQL Workload" -ComputerName HOST4
