Xspice usb redirection linux driver

Проброс USB устройств через SPICE

Собственно проблема в следующем. Есть виртуальная машина работающая через IOMMU+KVM+QEMU на FX-8350+Sabertooth R2. Хост генту: kernel-3.10-pf. Гость: Windows 7 64bit. Настроил spice для прокидывания устройств ввода, всё норм работает. Теперь захотелось в целях научнопознавательных и иследовательских завести USB Redirection.

Собрал значится всё что относится к QEMU и SPICE с USE=«usbredir». Выполнил настройку согласно этой хаутушке. Выставил права на /dev/bus/usb.

В итоге имеем следующее. В самой вирт. машине контроллеры появились. При коннекте с помощью spicy к вирт.машине можно галочками отметить пробрасываемые устройства. Устройство перестаёт работать на хосте, но в госте оно не появляется. Поэтому вопрос: как победить сию проблему?

QEMU запускается след. образом

Емнип, на живую оно пробросить не может, надо гостя ребутнуть.

Пробовал — не помогало. В инете было читано, что проброс осуществялется так: «If you plug in a device while the vm does not have keyboard focus, it will not get redirected, so you can use usb devices normally as long as you don’t have the vm focussed when you plug them in.»

У вас получилось?

У меня ситуация 1:1 с вашей. Тоже Gentoo, тоже Spice+QEMU. в spicy устройство забирается и комп его больше не видит, но в гостевой машине не появляется.

Скажите, вам удалось решить проблему?

Нет, забросил пока ту виртуалку, не до неё счас. Если где-то наткнётесь наткнётесь на решение, буду признателен, если поделитесь. =)

Всё оказалось просто

Christophe Fergeau 2014-03-10 23:48:21 UTC usb redirection was broken with spice-gtk 0.21

А именно она стабильна сейчас в Gentoo. Обновляемся до 0.25 и вуаля.

USB redirection using Spice #297

Comments

dJani97 commented Aug 15, 2020

I am trying to pass through an iPhone device to the VM. The steps I have tried:

1) I set up Spice in basic.sh :

2) I launch the Spice client

using the remote-viewer command, and successfully connect to spice://localhost:3001 .
I can see my Mac now using Spice 🙂

3) I try redirecting a USB device

I go to File -> USB device selection, and select a device. But when I’m trying to redirect any actual USB device (let it be my iPhone, or a simple USB mouse or keyboard) I get the following error on the remote-viewer console:

I am not insisting on using Spice, I just want to get my iPhone connected with the VM, and this seemed like a nice way to achieve this.

Can anybody help with this?

The text was updated successfully, but these errors were encountered:

Is the VM using the USB Controller version 3.0?

reinismu commented Aug 17, 2020

I haven’t seen anyone you have managed to passthrough iPhone without passing whole USB controller. If you manage to achieve it with spice, let us know 🙂

Is it possible to pass through my USB controller if I only have a single one? I’m trying to achieve this from a laptop.
It’s not a problem that it won’t be available to the host OS during this time.

reinismu commented Aug 17, 2020

It is possible, but you will lose your keyboard/mouse. You could write script that does it all and you get control of Mac. From Mac ssh into host and have script ready to switch controller back. Tho it would be a pain.
I just realized my work laptop has 2 USB controllers. So happy (razer blade 13)

To me, hwinfo —short gives the following:

Does it mean that I also have two controllers? It’s a pretty large machine (Dell Inspiron 7720), I wouldn’t be surprised.

Edit: I also checked the result of lsusb , not sure if it’s relevant:

usbredir

usbredir is the name of a network protocol for sending USB device traffic over a network connection. It is also the name of the software package offering a parsing library, a usbredirhost library and several utilities implementing this protocol.

The protocol is documented here, this document also explains what is meant with a usbhost and a usbguest.

usbredir was created for use with Spice, which is why it is hosted on spice-space.org, but the protocol and the usbredirhost are completely independent of spice, they could for example also be used to create a vnc extension for redirecting USB devices over a vnc connection to a qemu virtual machine.

The usbguest side is currently only implemented for qemu, and shipped as part of qemu (enabling this in qemu requires the libusbredirparser library to be available when building qemu).

usbredir supports USB device filtering configurable by a filter string

Host Configuration

For redirection to work, the virtual machine must have a supported USB controller. Qemu supports both USB2 and USB3, but at the time of writing, USB3 has had less testing. For USB2 support, the guest must have a EHCI controller and companion UHCI controller (companion UHCI is needed in order to support also USB1.x devices). For USB3 support, an XHCI controller is required. It also needs to have Spice channels for USB redirection. The number of such channels determine the number of USB devices that it’s possible to redirect at the same time.

More information about USB controllers in qemu could be found here.

Using virt-manager

Virtual machines created with virt-manager should have a USB controller by default. In the virtual machine details, select «Controller USB» in the left pane. If you only need to support USB2 devices, make sure its model is set to «USB2». For USB 3.0 support, select «USB3» for the model type.

You can then click on «Add Hardware» and add «USB Redirection» items as the number of USB devices you want to be able to redirect simultaneously.

Using libvirt

The following libvirt XML will configure a guest with USB2 support and the ability to redirect 3 devices simultaneously:

For USB3 support, the configuration can be simplified to:

Using QEMU

The following qemu options will configure a guest with USB2 support and the ability to redirect 3 devices simultaneously

For USB3 support, the configuration can be simplified to:

Client Configuration

The client needs to have support for USB redirection. In remote-viewer, you can select which USB devices to redirect under the «File->USB device selection» menu once the Spice connection is established. There are also various command line redirection options which are described below and when running remote-viewer with —help-spice.

To get USB redirection working on Windows clients, you need to install UsbDk

Filter String Format

A filter is used to set blocking or autoconnect rules for USB devices. It consists of one or more rules, where each rule has the form of:

Use -1 for class/vendor/product/version to accept any value.

And the rules themselves are concatenated like this:

rule1|rule2|rule3

A client’s default auto-connect filter string is 0x03,-1,-1,-1,0|-1,-1,-1,-1,1

This filters out HID (class 0x03) USB devices from auto connect and auto connects anything else. Note the explicit allow rule at the end, this is necessary since by default all devices without a matching filter rule will not auto-connect.

Client Filtering

Set a string specifying a filter to determine which USB devices, when plugged in, are allowed/blocked to auto-redirect USB traffic to the guest (client’s window has to be in focus).

Set a string specifying a filter to determine which USB devices, that are already plugged in, to redirect on connect once Spice connection is established.

Host Filtering

Set a string specifying a filter to determine which USB devices are allowed/blocked to redirect USB traffic to the guest.

Using QEMU

Note that in a QEMU command, the filter string should use a ‘:’ character as a separator within the rule.

Using libvirt
