How Can I Recover a Windows ECS with an Abnormal Virtualization Driver?

Updated on 2024-04-15 GMT+08:00

Background

An error occurs in the virtualization driver on a Windows ECS because of improper running of Tools. To ensure proper ECS running, handle this issue by following the instructions provided in this section.

Issue Description

The virtualization driver of an ECS became abnormal and this affected the data security, availability, and performance of the ECS.

The impact of this issue is as follows:

  1. The file system may be damaged.

    When you stop or restart such an ECS on the management console, the ECS will be forcibly stopped or restarted due to the lack of the virtualization driver Tools.

  2. Services on the ECS may become unavailable

    The affected ECS cannot be hot migrated between physical servers. If the host accommodating such an ECS becomes faulty or the hardware of the host is maintained, the ECS cannot be migrated to another host, affecting service high availability.

  3. The network and storage performance of the ECS deteriorates.

    The virtualization driver can improve the ECS network and storage performance. When the virtualization driver becomes abnormal, the network and storage performance will deteriorate.

Scenarios

  • Scenario 1

    Tools is not installed on the Windows ECS.

  • Scenario 2

    Tools has been uninstalled from the ECS.

Procedure

To install Tools on the Windows ECS, do as follows:

  1. Obtain the Tools installation package pvdriver-windows.zip.

    Contact the administrator to obtain the installation package.

  2. Decompress the software package and double-click setup.exe to start the installation.

  4. Click Install to start the installation.
    Figure 2 Installation progress
  5. Click Finish to complete the installation.
