Solutions for Preflight Check Items of Hyper-V VMs

The following tables describe the solutions to help you resolve errors and warnings from your Preflight Check results for Hyper-V VMs:

Hyper-V Credentials

Status

Message

Solution

Error

Failed to access the ADMIN$ share of the Hyper-V server or does not have the proper credentials.

  • Verify if the Hyper-V server is running
  • Verify if the network of Hyper-V server is connectable.
  • Verify if the ADMIN$ share of Hyper-V Server is enabled.
  • Provide administrator rights of Hyper-V when importing VM from it.

Integration Services

Status

Message

Solution

Warning

Not installed, running, operational.

Install/Upgrade/Enable the integration services.

Notes:

  • For Windows VM, if the integration services are installed, verify if the following two required services are running in the VM: Hyper-V Data Exchange Service and Hyper-V Volume Shadow Copy Requestor. Also verify, if there are errors of Hyper-V services in the event log of VM.
  • For Linux VM, verify the latest integration services are installed, and Key-Value Pair and Live virtual machine backup features are available on the specific Linux VM. For more information on Linux-integrated services on Hyper-V VM, see the Microsoft KB article.

Warning

The integration service inside the virtual machine is not compatible with the integration service in the Hyper-V server.

Create an agent-based backup plan in Arcserve UDP or use Arcserve UDP Agent to back up the VM.

Warning

Out of date.

Upgrade the integration services.

Power State

Status

Message

Solution

Warning

Powered off.

Power on the virtual machine.

Warning

Suspended.

Power on the virtual machine.

Disk

Status

Message

Solution

Warning

The physical hard disk that is attached to the virtual machine will not be backed up.

Create an agent-based backup plan in Arcserve UDP or use Arcserve UDP Agent to back up the virtual machine.

Warning

Unable to back up the disk on the remote share.

Create an agent-based backup plan in Arcserve UDP or use Arcserve UDP Agent to back up the virtual machine.

Warning

Failed to get the virtual machine by instance UUID.

Verify if the virtual machine exists on the Hyper-V server.

Data Consistency

Status

Message

Solution

Warning

An application-consistent snapshot is not supported. The virtual machine has a dynamic disk.

Create an agent-based backup plan in Arcserve UDP or use Arcserve UDP Agent to back up the virtual machine.

Warning

An application-consistent snapshot is not supported. The virtual machine has different file systems other than NTFS/Refs.

If you want to back up the virtual machine but skip the File Systems other than NTFS/Refs, create an agent based backup plan in Arcserve UDP or use Arcserve UDP Agent to back up the virtual machine.

Warning

An application-consistent snapshot is not supported. The Scoped Snapshot feature is enabled in the virtual machine.

Disable the Scoped Snapshot inside VM by adding a DWORD registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SystemRestore\ScopeSnapshots with the value 0.

Warning

An application-consistent snapshot is not supported. The integration service is not operational (Failed state).

Refer to the Integration Services column.

Warning

Failed to get the virtual machine by instance UUID.

Verify if the virtual machine exists on the Hyper-V server.

Warning

The virtual machine is not running.

Refer to the Power State column.

Warning

Failed to access the virtual machine.

Provide credentials with administrative privileges.
