A Guest OS driver must be installed on each Windows ECS to ensure that ECSs can run properly. For Xen-based ECSs, the Guest OS driver is a PV driver. For KVM-based ECSs, the Guest OS driver is called UVP VMTools. Before creating a private image using an image file on the cloud platform, you need to install the Guest OS driver provided by the platform. If an ECS has no Guest OS driver installed, its performance will deteriorate, and some functions will be unavailable.
You can download the Guest OS driver installation package and upload the package to the ECS using the Remote Desktop Protocol (RDP). You can also download the Guest OS driver installation package from the ECS.
This section describes how to upload the Guest OS driver package and install the Guest OS driver on a Windows ECS.
