Hyper-V 2012 R2, integration services issue on multiple VMs

Question

Hello,
I came to you because we encounter a technical issue on one of our Hyper-V (2012 R2).
Our backup (Veeam backup in last version) are still failing with error :
Guest processing skipped (check guest OS VSS state and integration components version)
After checking integration service states of those VMs on the Hyper-V, we get this result :
Get-VM | ft Name, IntegrationServicesVersion
Name                                                       
IntegrationServicesVersion
xxx-3REP-01                                                
6.3.9600.16384
xxx-ADMIN02
xxx-BAK02                                                  
6.3.9600.16384
xxx-MAIL-01
xxx-SCOM-01-1                                              
6.3.9600.16384
xxx-SQL02                                                  
6.3.9600.16384
xxx-VC-01                                                  
6.3.9600.16384
xxx-VD01
xxx-VMM02
xxx-VMM03
xxx-WEB01
Get-VMIntegrationService xxx-vmm02 | Select Name,OperationalStatus
Name                                                       
OperationalStatus
Time Synchronization                                       
{Ok}
Heartbeat                                                         
  {Ok, Ok}
Key-Value Pair Exchange                                  {LostCommunication}
Shutdown                                                          
{LostCommunication}
VSS                                                       
              {LostCommunication}
Guest Service Interface                                     {LostCommunication}
I already try to disable, then enable the operationalStatus :
Disable-VMIntegrationService -VMName MyVM -Name VSS,Shutdown,"Key-Value Pair Exchange"
Enable-VMIntegrationService -VMName MyVM -Name VSS,Shutdown,"Key-Value Pair Exchange"
The status is OK, but If I retry my backup I have the same error.
So, is there a way to reinstall integration service component without rebooting ?
Many thanks for your help.

Answer 1

On the Windows VMs that are not 2012 R2, insert the Integration media ISO, install it, and reboot.
When all is done, run this:
# Input:
$HVHost = "YourHostHere"
# Processing:
$VMInfo = @()
Get-VM -ComputerName $HVHost | where { $_.State -eq "Running" } | % {
$Info = New-Object -TypeName psobject
$Info | Add-Member "VMName" $_.Name
$Info | Add-Member "IntegrationServicesVersion" $_.IntegrationServicesVersion
$OS = Invoke-Command -ComputerName $_.Name { (Get-CimInstance Win32_OperatingSystem).version } -ErrorAction SilentlyContinue
$Info | Add-Member "OSVersion" $OS
$VMInfo += $Info
# Output:
$VMInfo | Out-GridView
$VMInfo | FT -AutoSize
$VMInfo | Export-Csv .\VMInfo.csv -NoTypeInformation
