PV USB Use Case for Xen 4.x

PV USB Use Case for Xen 4.x

[Tom Parker]

[-- Attachment #1.1: Type: text/plain, Size: 1325 bytes --]

Good Afternoon.  My colleague Stefan (sstan) was asked on the IRC
channel to provide our use case for PV USB in our environment.  This is
possible with the current xm stack but not available with the xl stack.

Currently we use PVUSB to attach a USB Smartcard reader through our dom0
(SLES 11 SP1) running on an HP Blade Server with the Token mounted on an
internal USB Port to our domU CA server (SLES 11)

The config file syntax is broken so we have to manually attach (I have
it scripted) whenever our hosts reboot (which is almost never.)

On the dom0 server I have to do the following steps:

*/usr/sbin/xm usb-list-assignable-devices* (get the bus-id of the USB
device)
*/usr/sbin/xm usb-hc-create $Domain 2 2* (Create a USB 2.0 Root Hub with
2 ports in $Domain)
*/usr/sbin/xm usb-attach $Domain $DevId $PortNumber $BusId* (Attach the
USB bus-id found in step 1 to the hub created in step 2)

On the domU the lsusb looks like this after the above (before it returns
nothing)
*
mgaca:~ # lsusb
Bus 001 Device 002: ID 04e6:5116 SCM Microsystems, Inc. SCR331-LC1
SmartCard Reader
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub*

Once I have done this I can use the usb devce in the domU as if it was
directly connected.

Thanks for your time.

Thanks for doing this.

At first glance this doesn't seem like something which we could do for
4.2.0 at this stage, although we should do it for 4.3 and potentially
consider it for 4.2.1.

Is it something which you guys might be interested in providing patches
for? It is at heart a moderately simple C coding exercise, I'm more than
happy to provide guidance etc. Much of the generic framework already
exists and there are examples in the form of other device types.

Can you give an example of what the syntax *should* be?

What (if anything) is the output of these commands?

Do you need to do anything to make a device "assignable"? (I get no
output from the list command for example)

Can you post the output of "xenstore-ls -fp" while the device is
connected?

Do you happen to know if this uses the PVUSB drivers or some other
mechanism? "lsmod" in both dom0 and domU should provide a clue if the
drivers are loaded.

Does this work for both PV and HVM guests or do you only use one or the
other?

Thank you for describing the functionality.

We should also update / keep up-to-date this wiki page:
http://wiki.xen.org/wiki/Xen_USB_Passthrough

already earlier I added the missing USB features to :
http://wiki.xen.org/wiki/XL_vs_Xend_Feature_Comparison

Worth a note: in xm/xend there are two different kind of USB passthru methods available:

1) Xen qemu-dm usb 1.1 passthru for HVM guests.
2) Xen PVUSB usb 2.0 passthru for both PV and PVHVM guests.

Hi Ian

Sorry to be slow to respond.  I missed this e-mail when you sent it.  I
will try to get the information you are looking for.

At this time we can't provide patches.  We are a sysadmin group and have
no programmers with experience in this.  It would take me a long time to
get back into C programming :)  Sorry.

There used to be some data in the wiki or in an initial presentation on
PVUSB but as it has never worked for me.  I don't remember how it worked.

Nothing.  They return silently if there is no error.

You just have to have a device that is not attached anywhere else.   For
example:

mgaxen1:~ # xm usb-list-assignable-devices
6-1          : ID 03f0:1027 HP Virtual Keyboard

That means that for the xm usb-attach (/usr/sbin/xm usb-attach $Domain
$DevId $PortNumber $BusId) part I would use the 6-1 as the $BusId

This is the part of the output that refers to the the vusb:
/vm/99a002ad-7c36-4a40-b9f5-545770f2d1b2/device/vusb = ""   (n0)
/vm/99a002ad-7c36-4a40-b9f5-545770f2d1b2/device/vusb/0 = ""   (n0)
/vm/99a002ad-7c36-4a40-b9f5-545770f2d1b2/device/vusb/0/frontend =
"/local/domain/3/device/vusb/0"   (n0)
/vm/99a002ad-7c36-4a40-b9f5-545770f2d1b2/device/vusb/0/frontend-id =
"3"   (n0)
/vm/99a002ad-7c36-4a40-b9f5-545770f2d1b2/device/vusb/0/backend-id =
"0"   (n0)
/vm/99a002ad-7c36-4a40-b9f5-545770f2d1b2/device/vusb/0/backend =
"/local/domain/0/backend/vusb/3/0"   (n0)

The rest of the output I have attached as a file.

Looks like it: 

dom0
mgaxen1:~ # lsmod | grep usb
usbbk                  23503  0
xenbus_be               3952  4 usbbk,netbk,blkbk,blktap
usbhid                 50900  0
hid                    83977  1 usbhid
usbcore               221920  5 usbbk,usbhid,uhci_hcd,ehci_hcd

domU
mgaca:~ # lsmod | grep usb
usbcore               220777  3 xen_hcd

PVUSB works for both PV and HVM guests.
And James Harper's GPLPV Windows drivers contain PVUSB frontend driver for Windows.
