[Xen-users] xen, openSUSE can not provide USB support my Windows XP guest HVM domain

[István HERCZEG <advoper@xxxxxxxxx>]

Dear All,


In short: xen (openSUSE) can not provide usb support to my HVM domain

I have a PC with Intel Core i5 650 CPU which provide all Intel VT extensions.
Intel® Core

My config: 
openSUSE 11.2
Linux linux-n0km 2.6.31.14-0.2-xen #1 SMP 2010-10-07 19:06:53 +0200 x86_64 x86_64 x86_64 GNU/Linux

xen
linux-n0km:~ # rpm -qa | grep xen
xen-3.4.1_19718_04-2.1.x86_64
xen-libs-3.4.1_19718_04-2.1.x86_64
kernel-xen-2.6.31.14-0.2.1.x86_64
xen-tools-3.4.1_19718_04-2.1.x86_64

I created a guest domain:
name="windowsxp-2"
uuid="3734fc01-e3e3-5cfa-a1dd-b3cc83af6786"
memory=1234
maxmem=1234
vcpus=2
>

localtime=1

builder="hvm"
extid=0
device_model="/usr/lib/xen/bin/qemu-dm"
kernel="/usr/lib/xen/boot/hvmloader"
boot="c"
disk=[ 'file:/var/lib/xen/images/windowsxp-2/disk0,hda,w', 'phy:/dev/sda1,hdb,w', 'phy:/dev/sr0,hdc:cdrom,r', ]
vif=[ 'bridge=br0,model=rtl8139', ]


stdvga=0
vnc=1
vncunused=1
apic=1
acpi=1
pae=1

usb=1
usbdevice= 'host:04a9:265f'
serial="pty"

according lsusb:
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 8087:0020  
Bus 001 Device 004: ID 04a9:265f Canon, Inc. MF5770
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 002: ID 8087:0020 

Using QEMU console command usb_add unsuccessful (see article bellow)

After starting my guest Windows XP, I can not find any USB devices in guest.

The best article that I found:
[Xen-users] Solved, but rather a crutch (Was: Passing USB device - Xen Source

The article contains some good idea like mounting /proc/bus/usb

After all, I can not use the usb under xen HVM domain.

Any help appreciated to resolve that deadlock situation.
advOPer
