Abstract

The invention discloses a method and a device for configuring a sound card for a KVM virtual machine in OpenStack, and the method comprises the following steps: 1), adding a method for configuring sound card equipment in a process of configuring KVM virtual machine equipment according to the business process of starting the virtual machine of the OpenStack; 2) adding a sound card equipment method,and adding a modem attribute to the sound card equipment, so that a user can set a sound card mode; 3) according to the method for configuring the sound card equipment, obtaining the operating systemattribute of the mirror image, and setting a corresponding sound card mode; and 4) after the configuration from the step (1) to the step (3) is completed, generating an xml file for configuring the KVM virtual machine by a subsequent process of the OpenStack, outputting the xml file to the libvirt by the OpenStack, and generating the KVM virtual machine by the libvirt according to the configuration file. According to the method provided by the invention, when a user uses a spice protocol or a windows remote desktop protocol, the sound in the desktop of the cloud can be transmitted to the client, and the sound collected by the microphone on the client can also be transmitted to the desktop of the cloud to be processed.

Description

technical field [0001] The invention relates to cloud computing technology, in particular to a method and device for configuring a sound card for a KVM virtual machine in OpenStack. Background technique [0002] OpenStack is currently the most widely used open source cloud computing framework, and it is still under continuous development and improvement. Cloud desktop is an application method of cloud computing. It is easy to maintain and has higher data security. It is a popular application method. At present, in OpenStack, the support for cloud desktop application scenarios is not perfect. The virtual desktop in the cloud cannot transmit the played media sound to the client, and the client cannot transmit the sound collected by the microphone to the cloud virtual desktop. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method and a device for configuring a sound card for a KVM virtual machine in OpenStack in...
