Virtual machine creation method and device and storage medium

The embodiment of the invention provides a virtual machine creating method and device and a storage medium, and the method comprises the steps that after a virtual machine creating request message is received, a system volume creating request message is sent to a cinder component, and the system volume creating request message is used for triggering the cinder component to create a system volume; a host creation request message is sent to a schema component, wherein the host creation request message is used for triggering the schema component to select a target computing node; and the target computing node is called to create a virtual machine based on the system volume. According to the embodiment of the invention, the step of creating the system volume without a direct association relationship with the computing node is executed before the step of determining the computing node, and a serial request computing, network and storage resource mode is changed into a parallel request storage resource and computin
