# Usage:
# Get-VMDetails -VMHost $VMHost -Template $Template -HardwareProfile $HardwareProfile -HDDPart $HDDPart -Network $Network -ExcludedHDD $ExcludedHDD -ExcludedNetwork $ExcludedNetwork

# Params:
# $Template = Virtual Machine Template for Deploy
# $HardwareProfile = Hardware Profile for Template
# $VMHost = One of your Hyper-V Servers' Name in VMHosts (like hyperv02 or Auto)
# $HDDPart = Hard Disk Partition (like C:, D:, E: or Auto)

# Example: Get-VMDetails -VMHost hyperv02 -Template W2K8R2STDT1 -HardwareProfile TEMP2GB -HDDPart Auto -Network Auto -ExcludedHDD "C:" -ExcludedNetwork "Backup Network"

# Gets Template and Hardware Details
