USB in DomU

USB Geräte in DomU einbinden

Zuerst die USB Geräte in der Dom0 herausfinden:

xen0:~# lspci | grep -i usb
00:1d.0 USB Controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI Controller #1 (rev 01)
00:1d.1 USB Controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI Controller #2 (rev 01)
00:1d.2 USB Controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI Controller #3 (rev 01)
00:1d.7 USB Controller: Intel Corporation 82801DB/DBM (ICH4/ICH4-M) USB2 EHCI Controller (rev 01)
xen0:~#

PCI Devices mittels LateBinding in DomU einbinden:

• USB Gerät identifizieren
• Betroffene Module entladen (usb*)
• Device ins PCI Backend exportieren

xen0:~# cat /proc/bus/usb/devices | grep P: | grep -v "Vendor=0000"
P:  Vendor=04a9 ProdID=1093 Rev= 1.10
xen0:~#
xen0:~# lsmod

Einträge in DomU Konfiguration:

pci     = [ '00:1d.1','00:1d.2','00:1d.0','00:1d.7' ]
