Revision as of 02:28, 30 October 2012
Description
Set your guest up with a USB3 controller and passthrough a USB3 device to your guest.
Setup
A functioning F18 VM, a host with USB3 ports and a physical USB3 device.
How to test
- Make sure the VM is stopped. Edit the VM configuration like:
virsh edit f18
- Remove all devices like <controller type='usb... and add the following:
<controller type='usb' model='nec-xhci'/>
- Save and exit. Start the guest, connect with virt-manager and log in to the guest.
- In the virt-manager hardware view, Add Hardware->USB Host Device, select your USB3 device to attach to the guest.
FIXME how to verify it's seen as USB3.0?
FIXME what are expected speed increases?
lsusb, then lsusb --verbose -s 001:002
cd /run/media/$user/dev ; dd if=/dev/zero of=./test.out count=2M (1G of data)
Expected Results
No obvious errors occur. USB device is detected as USB3 in the VM, functions correctly, speed increases?
