i'm running OS 11.1's

xen-3.3.1_18494_03-1.8

on

2.6.27.20-5-xen x86_64

from .../Kernel:/SL111_BRANCH/openSUSE_11.1/.

pci passthrough of ethernet from Dom0 to guests works fine.

i recently added a USB 10/100 Ethernet adapter to my mix.

@ Dom0,

lsusb | grep -i Belkin
Bus 001 Device 004: ID 050d:0121 Belkin Components F5D5050 100Mbps
Ethernet
dmesg | egrep -i belkin
pegasus 2-4:1.0: eth1, Belkin F5D5050 USB Ethernet, 00:05:1b:42:16:f3

it's fully functional.

digging to see how to passthrough the single USB dev to a guest, i
came across a presentation from the recent Xen/Oracle summit:

"Paravirtualized USB Support for Xen: Status Update"
www.xen.org/files/xensummit_oracle09/PVUSB.pdf

which seems to indicate that support for single-device passthru
exists, works, and has decent (~80% of native) performance.

iirc, it's currently targeted @ upstream xen sources, and can't be
simply/blindly applied to OS's xen sources.

anyone know if there _is_ any current effort/progress on per-device
USB PV support in OS/SLES?
