If you have special characters in your VM names, you may need to modify your XML files to fix reporting page.
Some characters (like &) may be special in XML, so you may need to change them to fix reporting page.
This is a simple script to search for “&” character in all XML files and replace them via “&”.
Thanks to Bill Stewart for Replace-FileString cmdlet. I made it a function to use in my case:

# Replace-FileString.ps1
# Written by Bill Stewart (bstewart@iname.com)
#
# Replaces strings in files using a regular expression. Supports
# multi-line searching and replacing.
#requires -version 2
<#
.SYNOPSIS
Replaces strings in files using a regular expression.
.DESCRIPTION
Replaces strings in files using a regular expression. Supports
multi-line searching and replacing.
.PARAMETER Pattern
Specifies the regular expression pattern.
.PARAMETER Replacement
Specifies the regular expression replacement pattern.
.PARAMETER Path
Specifies the path to one or more files. Wildcards are permitted. Each
file is read entirely into memory to support multi-line searching and
replacing, so performance may be slow for large files.
.PARAMETER LiteralPath
Specifies the path to one or more files. The value of the this
parameter is used exactly as it is typed. No characters are interpreted
as wildcards. Each file is read entirely into memory to support
multi-line searching and replacing, so performance may be slow for
large files.
.PARAMETER CaseSensitive
Specifies case-sensitive matching. The default is to ignore case.
.PARAMETER Multiline
Changes the meaning of ^ and $ so they match at the beginning and end,
respectively, of any line, and not just the beginning and end of the
entire file. The default is that ^ and $, respectively, match the
beginning and end of the entire file.
.PARAMETER UnixText
Causes $ to match only linefeed (\n) characters. By default, $ matches
carriage return+linefeed (\r\n). (Windows-based text files usually use
\r\n as line terminators, while Unix-based text files usually use only
\n.)
.PARAMETER Overwrite
Overwrites a file by creating a temporary file containing all
replacements and then replacing the original file with the temporary
file. The default is to output but not overwrite.
.PARAMETER Force
Allows overwriting of read-only files. Note that this parameter cannot
override security restrictions.
.PARAMETER Encoding
Specifies the encoding for the file when -Overwrite is used. Possible
values are: ASCII, BigEndianUnicode, Unicode, UTF32, UTF7, or UTF8. The
default value is ASCII.
.INPUTS
System.IO.FileInfo.
.OUTPUTS
System.String without the -Overwrite parameter, or nothing with the
-Overwrite parameter.
.LINK
about_Regular_Expressions
.EXAMPLE
C:\>Replace-FileString.ps1 '(Ferb) and (Phineas)' '$2 and $1' Story.txt
This command replaces the string 'Ferb and Phineas' with the string
'Phineas and Ferb' in the file Story.txt and outputs the file. Note
that the pattern and replacement strings are enclosed in single quotes
to prevent variable expansion.
.EXAMPLE
C:\>Replace-FileString.ps1 'Perry' 'Agent P' Ferb.txt -Overwrite
This command replaces the string 'Perry' with the string 'Agent P' in
the file Ferb.txt and overwrites the file.

Following script could be used to find similar virtual machines in same Cluster or Hyper-V Host.
This is very useful to split virtual machines if they have same workloads.
For example if you have two virtual machines with same workload like:
IISServer01
IISServer02
This script will find them and list them with a useful output. You should use it on SCVMM 2012 R2 Console:

} You can define Cluster and Hyper-V Host in function to minimize scope.
For Hyper-V Host Specific Search:
Get-SimilarVM -VMHostName "VMHOST01" |
Get-SimilarVM -VMHostName "VMHOST01" For Cluster Specific Search:
Get-SimilarVM -ClusterName "VMHOSTCluster01" |
Get-SimilarVM -ClusterName "VMHOSTCluster01" Searching in all clusters:
You can customize output to see what you need.

You can use following script to get VMs with Passthrough Disks on SCVMM 2012 R2.
$VMs = Get-VM | Where HasPassthroughDisk |
$VMs = Get-VM | Where HasPassthroughDisk Then you can get virtual machine hardware information:
$VMs | ft Name,Status,CpuCount,Memory,TotalSize |
$VMs | ft Name,Status,CpuCount,Memory,TotalSize You will see pretty good output :)
