If you run Hyper-V managed by SCVMM 2008R2, and you run a Linux VM running the new Linux Integration Services, you will not be able to shut down the VM from the user interface of SCVMM200R2.
However, you can shut it down with PowerShell with the following cmdlet;
Get-VMMServer -computername localhost
$VM = Get-VM | where { $_.Name -eq "VMNAME" }
Shutdown-VM -VM $VM
