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