Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples, in attached drawing:
Fig. 1 is the method flow diagram of the embodiment of the present invention.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to embodiments, to the present invention
It is further elaborated.It should be appreciated that described herein, specific examples are only used to explain the present invention, is not used to limit
The fixed present invention.
As shown in Figure 1, a kind of is the method for KVM virtual machine configuration USB device in OpenStack,
By the analysis to source code, it is known that in the operation flow of OpenStack ,/nova/virt/libvirt/
The attribute that the required all virtual units and these equipment of config.py document definition have；/nova/virt/
Libvirt/driver.py document definition, it should those categories should be used using which kind of equipment and equipment to virtual machine
Property.OpenStack is equipment needed for configuring virtual machine by xml document.In order to give virtual machine configuration USB device, it is also necessary to
Increase device PCI in virtual machine.For USB device, needing to be arranged its model is " nec-xhci ", can be supported
USB3.0 equipment.Finally complete xml document is exported, virtual machine is generated according to configuration file to libvirt, libvirt.For
The windows virtual machine is enabled to drive USB3.0 equipment, it is also necessary to which the drive of USB3.0 is installed in Windows operating system
Dynamic program.It checks the virtual machine generated, has USB3.0 and device PCI in discovering device list；It is inserted on a client
The equipment of USB3.0 or USB2.0, cloud desktop client can identify the equipment, and operate to the equipment.
Specific step is as follows for this method:
1) increase add_usb_driver method in/nova/virt/libvirt/driver.py file, in this method
The model of middle configuration USB device, startport, index parameter.
2) increase LibvirtConfigGuestUSB class in/nova/virt/libvirt/config.py file,
The attribute that USB device is defined in such includes: type=usb, index, model, startport.
3) add_usb_driver method is called in _ get_guest_config method, and model=" nec- is set
Xhci ", startport=None, index=0.
4) increase add_pci_driver method in/nova/virt/libvirt/driver.py file, in this method
Type, index, model parameter of middle PCI allocation equipment.
5) increase confGuestPCI class in/nova/virt/libvirt/config.py file, defined in such
Type, index, model attribute.
6) add_pci_driver method is called in _ get_guest_config method, and type=pci, index are set
=0, model=' pci-root '.
7) follow-up process of OpenStack will generate the xml document of configuration KVM virtual machine, and OpenStack is by the xml
File, which is exported, generates KVM virtual machine according to configuration file to libvirt, libvirt.
8) driver of USB3.0 is installed in an operating system, the hardware for enabling operating system to drive USB3.0 is set
It is standby.
According to above method, it is the dress of KVM virtual machine configuration USB device in OpenStack that we, which are easy to get a kind of,
It sets, comprising:
