| |
| − | Add support for USB 2.0 controller
| |
| − | ====================================================
| |
| − | | |
| − | Users have requirements of using USB device, the detailed information can refer
| |
| − | to BP in https://blueprints.launchpad.net/nova/+spec/usb-passthrough.
| |
| − | | |
| − | If not specify appropriate USB controller for USB device, USB device will
| |
| − | use the default piix3-usb-uhci, which results in some problems.
| |
| − | | |
| − | 1. The low speed of USB device.
| |
| − | | |
| − | 2. If use spice client to redirect USB device to VM, the mismatched speed may
| |
| − | prevent the connection.
| |
| − | | |
| − | | |
| − | USB 2.0 has other good point that it will result in dramatically lower CPU usage
| |
| − | when the USB tablet is present for VNC/SPICE.
| |
| − | | |
| − | As described above, I think that support USB 2.0 controller is valuable in
| |
| − | Openstack.
| |
| − | | |
| − | | |
| − | Problem description
| |
| − | ===================
| |
| − | tag
| |
| − | Use cases:
| |
| − | | |
| − | 1. User creates a VM, the system creates a default ehci USB controller, attach
| |
| − | USB tablet to the ehci controller.
| |
| − | | |
| − | | |
| − | Proposed change
| |
| − | ===============
| |
| − | tag
| |
| − | 1. Add function of create ehci controller in libvirt driver when create
| |
| − | VM.
| |
| − | | |
| − | 2. Add function of specify USB controller for USB tablet in libvirt driver
| |
| − | when create VM.

| |

| |
| − | 1. Use object 'LibvirtConfigGuestController' for USB controller in libvirt driver,
| |
| − | create ehci xml in 'get_guest_config' function.
| |
| − | | |
| − | The xml may like:
| |
| − | | |
| − | <controller type='usb' index='1' model='ehci'/>
| |
| − | | |
| − | All values of above properties are constant.
| |
| − | | |
| − | 2. Add 'address' element to USB tablet object 'LibvirtConfigGuestInput',
| |
| − | specify ehci controller in 'get_guest_config' function.
| |
| − | | |
| − | The xml may like:
| |
| − | | |
| − | <input type='tablet' bus='usb'>
| |
| − | | |
| − | <address type='usb' bus='1' port='1'/>
| |
| − | | |
| − | </input>
| |

| |
| − | Support function of USB-redirection
| |
| − | ===================================
| |
| − | | |
| − | We provide VDI(Virtual Desktop)solution for customers, our customers have strong
| |
| − | requirements for using USB devices.
| |
| − | | |
| − | The typical use cases and our solutions are described as below:
| |
| − | Customers want to use local USB printers or USB scanners with
| |
| − | TC(Thin-Client), because remote desktop protocol like ICA have already supported
| |
| − | USB-redirection, so customers only need to attach USB device to TC, the protocol
| |
| − | can map USB device to VM.
| |
| − | | |
| − | | |
| − | Problem description
| |
| − | ===================
| |
| − | tag
| |
| − | | |
| − | Use cases 1:
| |
| − | | |
| − | A end user wants to print some documents in cloud environments, him perform the
| |
| − | following steps:
| |
| − | | |
| − | 1. Create a VM with virtual USB-redirection devices.
| |
| − | | |
| − | 2. Use TC with spice client to connect to VM, insert USB printer to TC, select
| |
| − | printer to redirect to VM in GUI of spice client.
| |
| − | | |
| − | 3. User can see printer in VM and use printer to print documents.
| |
| − | | |
| − | Use cases 2:
| |
| − | | |
| − | A end user wants to take a video chat with friends in cloud environments, him
| |
| − | perform the following steps:
| |
| − | | |
| − | 1. Create a VM with virtual USB-redirection devices.
| |
| − | | |
| − | 2. Use TC with spice client to connect to VM, insert USB camera to TC, select
| |
| − | camera to redirect to VM in GUI of spice client.
| |
| − | | |
| − | 3. User can see camera in VM and take video chat with friends.
| |
| − | | |
| − | Use cases 3:
| |
| − | | |
| − | A end user wants a on-line shopping, which needs a USB-key for more secure payment.
| |
| − | | |
| − | 1. Create a VM with virtual USB-redirection devices.
| |
| − | | |
| − | 2. Use TC with spice client to connect to VM, insert USB-key to TC, select
| |
| − | USB-key to redirect to VM in GUI of spice client.
| |
| − | | |
| − | 3. User can see USB-key in VM, the security check and payment plugin in
| |
| − | Browser like IE can use USB-key for authentication.
| |
| − | | |
| − | | |
| − | Proposed change
| |
| − | ===============
| |
| − | tag
| |
| − | | |
| − | 1. Add function of create USB-redirection device in libvirt driver.
| |
| − | | |
| − | 2. Support specify USB-redirection device in image properties and create VM
| |
| − | with this kind of image. If libvirt driver find this kind of property it then
| |
| − | construct related xml.
