The alert is triggered when the Hyper-V Integration service in the guest machine is either not installed or not up-to-date. The article provides solutions to resolve this issue and enable successful Appware backup.
Cause:
The alert arises during Appware enabled Hyper-V backups when the Integration service of the guest machine is missing or outdated.
Solution:
To address the issue of processing guest VMs with outdated Hyper-V Integration service, follow the solutions provided below based on the version of the Hyper-V Host OS.
Case 1: Hyper-V Host OS Below or Equivalent to 2012 R2
1. Open Hyper-V Manager.
2. Click on the target guest machine.
3. Observe Integration Services status on the right-hand side.
4. If not up-to-date, select "Guest VM Interface" -> "Actions" -> "Insert Integration Services Setup Disk."
5. Connect the guest machine and run the Integration Service Setup Disk.
6. Reboot the guest machine.
7. Confirm Integration Services state is up-to-date.
8. Schedule an Appware backup for the guest machine.
Case 2: Hyper-V Host OS Above 2012 R2
1. Run the PowerShell command on the Hyper-V host:
$VMMS = gwmi -namespace root\virtualization\v2 Msvm_VirtualSystemManagementService
$RequestedSummaryInformationArray = 1,123
$VMMS.GetSummaryInformation($null,$RequestedSummaryInformationArray).SummaryInformation
2. Check the 'IntegrationServicesVersionState' value against the guest machine name:
  1. Integration Service state is up-to-date.
  2. Integration service needs an update or is not up-to-date.
3. If not up-to-date, update the guest VM via Windows Update.
4. Reboot the guest machine.
5. Confirm Integration Services state is up-to-date.
6. Schedule an Appware backup for the guest machine.
