tag 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.

Alternatives

None

Data model impact

tag 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>

The values of address are constant.

All values of above properties are constant. The USB-redirection device use port 2 of echi controller. BTW: The BP about echi controller can refer to https://review.openstack.org/#/c/88334/
