Installing the PV Driver


After an ECS is created and it has an OS installed, you can install the PV driver on the ECS to improve its I/O processing performance and enable hardware monitoring and other advanced functions.

Run the following command to check whether the PV driver is the latest in the version configuration file:

C:\Program Files (x86)\Xen PV Drivers\bin\version



  • The ECS has an OS installed and an EIP bound.
  • The ECS system disk has greater than 32 MB of available capacity.
  • You have obtained the administrator account if the ECS runs Windows Server 2008.
  • You have downloaded the PV driver software package. For how to obtain the software package, see Obtaining Required Software Packages.

Installing the PV Driver

  1. Log in to the ECS using VNC.

    For how to log in to the ECS, see the Elastic Cloud Server User Guide.

  2. On the ECS, choose Start > Control Panel.
  3. Click Uninstall a program.
  4. Uninstall GPL PV drivers for Windows x.x.x.xx as prompted.
  5. Download the PV driver matching the ECS OS listed in Obtaining Required Software Packages.
  6. Decompress the PV driver software package.
  7. Right-click GPL PV Drivers for Windows x.x.x.xx, select Run as administrator, and complete the installation as prompted.
  8. Restart the ECS to make the PV driver take effect.

    For ECSs running Windows Server 2008, you must restart them twice.


    After the PV driver is installed, the NIC configuration of the ECS will be lost. If you have configured NICs before the PV installation, you need to configure them again.
