Embodiment Construction

[0027] Below, in conjunction with accompanying drawing and specific embodiment, the present invention is described further:

[0028] A method for configuring virtual machine DNS based on XEN, such as figure 1 shown, including the following steps:

[0029] Step 101, the management module reads configuration parameters from the storage module through the driver module, and the configuration parameters include DNS parameters and MAC addresses;

[0030] The management module is an Agent module, and the Agent is a module in XenServer Tools and a service installed in the XEN virtualization layer; the virtual machine can be managed through it.

[0031] The driver module is a PV Driver, and the PV Driver is used to improve the I / O processing performance of the virtual machine disk and the network, and provide an interface for the Agent module to communicate with the XEN virtualization layer.

[0032] The storage module is a storage module of the XEN virtualization layer: Xenstore mo...

Abstract

The invention discloses a method and system for configuring a virtual machine DNS based on XEN. The method comprises the following steps: S1, a management module reads configuration parameters from a storage module through a driving module, wherein the configuration parameters comprise DNS parameters and an MAC address; and S2, the management module obtains a corresponding network card according to the MAC address, and sets the DNS parameters set in the network card. The method and system disclosed by the invention has the advantages that an interface of a virtual machine IP is set in XenServerTools, the DNS settings of the windows virtual machine are increased, and a function of configuring the DNS in the XEN virtual layer is achieved.

Description

technical field [0001] The invention relates to a method and system for configuring virtual machine DNS based on XEN. Background technique [0002] In the Xen virtualization layer, XenServer Tools is installed inside the virtual machine after the virtual machine is created to optimize and manage the virtual machine. XenServer Tools includes: a driver module and a management module. The driver module is a paravirtualization driver, namely Para-Virtualization Driver, PV Driver for short; the management module is an Agent module. The PV Driver is used to improve the I / O processing performance of the virtual machine disk and network and provide an interface for the Agent module to communicate with Xen; the Agent module provides an interface to set the virtual machine and provide the function of monitoring the running status of the virtual machine. [0003] The Agent module in XenServer Tools only provides interfaces for setting the IP, Netmask and Gateway of the virtual machine...
