[opensuse-virtual] paravirtualized USB support (per-device passthrough) in OS 11.1
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? -- To unsubscribe, e-mail: opensuse-virtual+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-virtual+help@opensuse.org

That's correct.

There are no efforts currently being made to address this with a custom solution within OS/SLES. The community's solution will most likely be picked up in the first openSUSE release following the inclusion of this feature into an official xen release (xen 3.4, for example). If this feature makes XEN 3.4, it will likely be included in openSUSE 11.2.
