Either function will do, it's the same, Shutdown from Hyper-V Manager will instruct the VM to shutdown, as id you were logged into the VM.<br />
<br />
So save yourself a few minutes, use Hyper-V Manager, Shutdown Guest.

Hello,<br />
&nbsp; &nbsp; &nbsp;So I have a situation where a power supply is going bad that powers my network switch that is the iSCSI connection to my 2008 R2 Hyper-V virtual machines. &nbsp;I need to move this switch over to a new power supply and was hoping I could use the &quot;Pause&quot; function in hyper-v manager for all of the VMs that are running on that server and then simply connect the switch and power it back up on a new power supply. &nbsp;Is this possible without harming the VMs? &nbsp;Will the VMs resume properly after being paused and basically having the connection to the virtual disks broken for a few minutes? &nbsp;<br />
<br />
Thanks

Hello,
     So I have a situation where a power supply is going bad that powers my network switch that is the iSCSI connection to my 2008 R2 Hyper-V virtual machines.  I need to move this switch over to a new power supply and was hoping I could use the "Pause" function in hyper-v manager for all of the VMs that are running on that server and then simply connect the switch and power it back up on a new power supply.  Is this possible without harming the VMs?  Will the VMs resume properly after being paused and basically having the connection to the virtual disks broken for a few minutes?  

Thanks

Can I pause a 2008 R2 Hyper-V VM and replace the network switch where the virtual disks and settings reside without damaging/corrupting the VM?

Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.

Virtualization

Windows Server 2008 and Windows Server 2008 R2, based on the Microsoft Vista codebase, is the last 32-bit server operating system released by Microsoft.
