To fix this problem, remove the existing version from the operating system on the virtual machine. Ensure that you have installed the latest version of Hyper-V and then install integration services again. Check virtual machine state If you were trying to take a VSS snapshot, try manually saving the virtual machine and then retry the VSS snapshot operation. If you were trying to restore a VSS snapshot, try turning off the virtual machine manually and then retry the restore operation. If you tried an abort of the writer operation or if the backup application has crashed, set the virtual machine to the running state manually and then try the backup operation again after the state transition is completed. Check Guest for failed VSS Snapshot Please check the event log in the guest to analyze why the VSS snapshot failed and then retry the operation. Retry VSS snapshot operation Retry the VSS Snapshot operation. Retry the restore operation Retry restoring the virtual machine from backup. Check file location Change the restore location and then try the operation again. Check VDEV version Ensure that the version of the virtual device driver (VDEV) installed in the virtual machine matches that of the virtualization server (somteimes called a host). If not, reinstall the integration components in the virtual machine. Verify : The integration services are all shown in a running state in the service control manager of the virtual machine. All the guest Hyper-V drivers are in a healthy state. Additionally, any operations that involve the integration services complete successfully. |
