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

Updated at: Dec 16, 2019 GMT+08:00

Background

An error occurs in the virtualization driver on a Windows ECS because Tools is not properly running. To ensure proper ECS running, handle this issue by following the instructions provided in this section.

Issue Description

The virtualization driver of some ECSs became abnormal, which affected the data security, availability, and system performance of these ECSs.

The impact of this issue is as follows:

  1. The file system of these ECSs might be damaged.

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

  2. Services on the ECSs become unavailable.

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

  3. The network and storage performance of the ECSs is deteriorated.

    The virtualization driver improves the network and storage performance of ECSs. Therefore, when the virtualization driver becomes abnormal, the network and storage performance is deteriorated.

Scenarios

  • Scenario 1

    A Windows ECS has no Tools installed.

  • Scenario 2

    The virtualization driver of an ECS has been uninstalled.

Procedure

Perform the following operations to install Tools on the Windows ECS:

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

    To download the installation package, log in at https://ecs-instance-driver.obs.myhwclouds.com/pvdriver-windows.zip.

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